The SAE in conjunction with the FAA, Transport Canada, airlines, aircraft manufacturers, and producers of deicing fluids develop and publish specific procedures for aircraft ground deicing. 0000152037 00000 n The sample may have a cloudy or hazy appearance or a solid slug of water. Can I taxi to the end of the ramp without permission, or do I call before releasing the brakes? Why should an aircraft technician become familiar with standard light signals? A couple of ASRS reports illustrate Taxiways generally also have better signage and markings than runways, which can add to the confusion at an already. ASRS reports also indicate that problems Continue searching. 0000041365 00000 n ASRS reports reveal that some precautions aircraft taxiing hazards and remedy - howtostarta.net et@ dfcd1@ 0 All comments made here are public and may be republished by Flying. As a general rule, only rated pilots and qualified airframe and powerplant (A&P) technicians are authorized to start, run up, and taxi aircraft. Proper effective scanning for other aircraft, surface vehicles, or other objects should be continuously exercised in all cases, At those airports where the U.S. Government operates the control tower and ATC has authorized noncompliance with the requirement for two-way radio communications while operating within the Class B, Class C, or Class D surface area, or at those airports where the U.S. Government does not operate the control tower and radio communications cannot be established, pilots must obtain a clearance by visual light signal prior to taxiing on a runway and prior to takeoff and landing, Leaning the mixture could be helpful to save fuel, avoid fouled spark plugs, and reduce emissions when using 100LL during long taxi's or long waits for takeoff, If leaning, always remember to move the mixture back to rich before takeoff, Taxi speed is not explicitly regulated; however, common sense must apply so as not to operate in a "careless or reckless manner" (, While on a ramp, you should not taxi any faster than one can walk, While on a taxiway, you should not taxi faster than one can jog, When entering a turn, be mindful of the stress you are placing on the landing gear as you turn, Care must be exercised when taxiing at night, in low visibility, or toward the sun to remain situational awareness as to where you are and what is around you, This means half the speed and twice the caution, Runways are generally flat surfaces however small changes in elevation will impact the speed at which the aircraft moves, You will require more power uphill and less downhill, Every turn you make will impact the amount of power required to some degree, It is unlikely however, that you'll need to adjust than around 100 RPM to overcome to effects of slope, Avoid taxiing over any noticable dips on the surface that could put undue stress on the landing gear, or damage wheel pants, if applicable, If taxiing in cold weather conditions such as snow, ice, or slush, avoid taxiing over contaminated surfaces, if possible, If slush or ice is suspected to have contaminated the landing gear, consider touch-and-go's to clear ice from frozen gear, Taxi slower when objects on the surface have the potential to be kicked up onto the aircraft, Taxi speed is especially important in cold weather operations the aircraft may not only lose traction, but could kick up slush or water onto wings and control surfaces, increasing weight and possibly inhibiting range of motion, Crosswinds can effect an aircraft, even when moving at slower speeds on the ground during taxi, Moderate to strong headwinds and/or a strong propeller slipstream makes the use of the elevator sometimes necessary to control pitch, Downwind taxiing will usually require less power and may require none, but do not ride the brakes, The upwind wing will tend to be lifted by the wind unless the aileron control is held in that direction, Weathervaning may occur as the wind effects a large portion of the aircrafts side [, This is more apparent in a tail wheel aircraft given the wheel is farther behind the center of gravity and comparatively farther from the main gear, The aileron and elevator should be positioned in such a way as to prevent undesirable effects on the aircraft, Remember the memory aid to: dive away and fly into the wind, The elevator must be neutral (for tricycle gear airplanes) or up (for tailwheel airplanes), Remember also that turns will require change the direction the wind is coming from relative to the aircraft, requiring a change in control positions, It will require a large amount of power to initially move the aircraft, As the aircraft starts to move, power must be retarded, possibly as far back as idle, to prevent continued acceleration, Steer with rudders, keeping your feet over, but not on, the breaks, Riding the brakes will reduce their lifespan and could render them less effective, Many high performance aircraft can produce enough thrust that riding the brakes may be necessary to keep the aircraft from speeding up; brake judiciously, Jet aircraft can be dangerous when exhaust is swept across an area, Reduce the power to idle in a turn, but remember an aircraft stopped in a turn takes a lot of power to get moving again, Pilots and aircraft operators should be constantly aware that during certain low visibility conditions the movement of aircraft and vehicles on airports may not be visible to the tower controller, This may prevent visual confirmation of an aircraft's adherence to taxi instructions, If pilots become disoriented, it is vitally important to notify the controller immediately, Pilots should proceed with extreme caution when taxiing toward the sun, When vision difficulties are encountered pilots should immediately inform the controller, Advisory Circular 120-57, Low Visibility Operations Surface Movement Guidance and Control System, commonly known as LVOSMGCS (pronounced "LVO SMIGS") describes an adequate example of a low visibility taxi plan for any airport which has takeoff or landing operations in less than 1,200 feet runway visual range (RVR) visibility conditions. Continued use may reduce efficiency due to lead deposits on the turbine blades. }OWaMJMqh2AqFQZ-`/g25\_ R{jxHL{. Controlled movement of an airplane using its own power while on the ground. What are some of the possible outcomes of using a lower grade avgas than the specified grade? 0000061214 00000 n Even something as routine as taxiing Traction, braking, and directional control are reduced. These include: inappropriate use of a restricted taxiway - some taxiways are restricted by wingspan. Wildlife hazards during approach and landing should be treated like any other flight safety hazardif any doubt exists concerning safety, delay your landing until conditions are right. 0000061284 00000 n report revealed: Here are a few suggestions that can Other aircraft, vehicles, people and obstacles. to hold short of a particular runway or taxiway. to the taxiway and consist of two continuous and two dashed lines, each spaced xref All will be 12 inches in depth. In addition to the aforementioned items for vehicle operators, the tug operator must: know the size of the aircraft in tow inclusive of the wingspan, be conversant with the normal taxi routes from one airfield location to another, understand the stopping distances required for a tug with an aircraft in tow, comply with all clearances, especially runway crossing clearances, use wing and tail walkers when manoeuvring in congested areas. Adherence to these procedures has led to an accident free record for large aircraft commercial operations since the early 1990s. Pull the propeller through by hand for three or four complete revolutions. Can checklists be rewritten 0000138093 00000 n Captain may not hear or comprehend "hold short" clearances. At busy locations, however, pilots may be instructed by the ground controller to "contact clearance delivery" on a frequency designated for this purpose, No surveillance or control over the movement of traffic is exercised by this position of operation, Taxiing checklists are sometimes specified by the AFM/POH, and the pilot must accomplish any items that are required, If there are no specific checklist items, taxiing still provides an opportunity to verify the operation and cross-check of the flight instruments, Additionally, the heading indicator should not precess more than 3 in 15 minutes, These checks can be accomplished on conventional mechanical instrumented aircraft or glass cockpits, Do not perform any items while taxiing that prevent you from safely operating the aircraft, Complete all checklists required before taxi, Consider setting the heading bug/course indicator to display where the winds are coming from, Contact Clearance Delivery, as appropriate.

Sort, search, and view reports from completed Transportation Safety Board investigations. Become throughly trained. Use by a larger aircraft could compromise obstacle clearance, failure to follow taxi lane guidance - deviation from the lane guidance whilst manoeuvring in proximity to light stands, gates or stationary equipment can result in collision, jet blast -inappropriate thrust settings or following too closely can result in aircraft damage due to. Here are the top 5 mistakes I see routinely at our home airport. If this slush is not cleared prior to take-off, it may freeze in flight. obtain and read back any ground movement controller clearance prior to entering an area where clearance is required. Small general aviation aircraft should never use thickened fluids - especially Type II & IV but also Type III in most cases - because their rotation speeds are not high enough to completely shear the fluid off the wing. Hazards Associated With Flying at Night Presented by Name Transport Canada, System Safety. These accumulations may refreeze after take-off and impede control or gear movements later. 0000101142 00000 n These "failure to comply" occurrences most usually involve vehicles: In all cases, these actions have the potential to put the vehicle in conflict with an aircraft which, in turn, could: Most of the remaining occurrences are related to one of the following: Most taxiway accidents and incidents are preventable. This AC and its appendices provide guidance to airport operators about developing training programs for safe ground vehicle operations, personnel taxiing or towing an aircraft, and pedestrian control on the movement and safety areas of an airport. Riding the brakes while taxiing can lead to excessive wear on the pads and rotors and can generate excessive heat. If the engine doesn't start and the fire continues to burn, discontinue the start attempt and extinguish the fire with a suitable fire extinguisher. 0000261155 00000 n Always conduct a pre-takeoff check for frozen contaminants just prior to take-off. 0000011457 00000 n Foreign objects such as rocks, gravel, rags, or loose hardware. 0000012300 00000 n 0000010966 00000 n Type II fluids have a higher viscosity than Type I fluids due to the addition of thickening agents. Having precise control while taxiing will help as you manage directional control during the takeoff. This wake velocity can increase two or three times as the throttles are advanced and the airplane begins to taxi. Where can the standard aircraft taxi hand signals be found? 0000249683 00000 n What does the number 100 signify in 100LL aviation gasoline? their policies and procedures to look for and eliminate practices that could 0000248258 00000 n AC 150/5210-20A - Ground Vehicle Operations to include Taxiing or Sometimes Multiple infractions should be considered grounds for suspension of airside driving privileges. Then, a ground taxiing route optimization model which minimizes total taxiing time is proposed. Taxi and take-off in icing conditions present several unique hazards. Towards a more sustainable ground traffic management. Note: The definition includes collisions with an aircraft, person, ground vehicle, obstacle, building, structure, etc., but excludes ground collisions resulting from events categorized under Runway Excursion (RE . done safely requires planning, coordination, and attention. 0000138900 00000 n This will allow you to focus on your route and communication. 0000249761 00000 n Be certain you are using the correct fuel, properly ground the aircraft and refueling unit, and protect the aircraft surfaces from hose and nozzle damage. 0000005695 00000 n aircraft, vehicle, pedestrian, or other object while taxiing is about three Being in the exact center of the taxiway might not matter for the wingtips of your Cessna 150 that youre training in, but remember youre preparing for something bigger and faster, right? Describe the important precautions that should be observed when fueling an aircraft. Be sure the propeller or inlet area is clear and check for loose stones, gravel, etc. contribute to taxi distractions. 0000040502 00000 n The bowline (although other anti-slip knots may be used). six inches apart. Page updated: September 27, 2016. Runway Safety Application Keeps Taxiing Aircraft Out of Harm's Way These agents enable Type II fluids to remain on the aircraft surface during standing, taxi, and other low speed operations and to rapidly flow off due to wind shearing forces during take-off roll. If the signalman can see the pilots eyes, the pilot can see the signals. decrease the threat of runway transgressions? They should: provide the appropriate clearance for the requested action, ensure that the clearance readback is accurate, to the extent possible, monitor the movement visually, via transponder or by use of. Type IV fluids offer the best protection against refreezing. Training at a pilot-controlled airport and then flying to a towered field (or vice versa) can lead to communication confusion. Not so obvious is how handling may be affected by deicing fluids. No aircraft should attempt to take off with frost, snow, or ice adhering to wings, propellers, control surfaces, engine inlets, or other critical surfaces. 0000049616 00000 n https://studentpltnews-images.s3.us-east-2.amazonaws.com/wp-content/uploads/2018/05/05174018/702SP.jpg, https://flighttrainingcentral.com/wp-content/uploads/2022/01/FTC-logo-horizontal-fianl.png, Soft Field Takeoff HD Flight Maneuver Spotlight, Slow Flight HD Flight Maneuver Spotlight, Flight Start Helps Student Pilots Choose Their Path, Learn to Fly Month at Sportys begins Monday, May 1, Turns Around a Point Flight Maneuver Spotlight. This article examines collisions and near collisions whilst aircraft are on the airport manoeuvring areas inclusive of taxiways and ramp areas. Controller: It's important to understand that PDF Taxiing for Takeoff - ASRS First Officer write down the taxi clearance and holding instructions. problems are quite serious. And as Ground Collision ( GCOL) - a collision that occurs while an aircraft is taxiing to or from a runway in use. In response, we have issued some transportation-related measures and guidance. Deicing guidelines can be found in the FSAT, under "FAA Approved Deicing Program", and from the fluid manufacturer. [This led] to the assumption by the Captain that deicing had been completed." FAA's updated "advisory circular" includes newly defined items such as airport operations areas and non-movement areas, and offers guidance for towered airports regarding non-pilot workers and equipment in the runway safety area.

Flying may receive financial compensation for products purchased through this site. 0000253140 00000 n Windy Flight Operations - AOPA - Aircraft Owners and Pilots Association Well-developed ground deicing/anti-icing methodologies and procedures have been established for the airlines. A great flight instructor of mine once told me, You can either have power in or use the brakes, but you cant do both because that just doesnt make any sense. He was right. Also, ensure that the prop or jet blast doesn't blow into hangars or other airplanes, and have a fire guard nearby. 0000151754 00000 n b. never tow the aircraft while any of its engines are operating. Seeking the most efficient flight - Episode 4 : sustainable taxiing on 0000250038 00000 n 0000153503 00000 n Whilst all events do not result in collision with an aircraft, the majority of taxiway occurrences involve vehicle operators deviating from a surface movement controller clearance. What Does a Pilot Require To Remain Current in an Aircraft Requiring a Type Rating? 0000249961 00000 n is still off-frequency talking to the pushback crew on the interphone. 0000002158 00000 n Always taxi with your nosewheel on the centerline of the taxiway. d&&H`]0&+A$C,:fL`LLC You might sound weird, but it beats getting a verbal lashing from the tower. IF: You detect ice on your aircraft during the preflight inspection. Taxiway Collisions | SKYbrary Aviation Safety basic as it may seem, a few ASRS reports indicate that some pilots have difficulty 0000042021 00000 n 0000249260 00000 n The A/S32A-37 aircraft towing tractor is an inline, 6-cylinder, diesel-powered, liquid-cooled, 4-wheel drive vehicle used to move heavy aircraft. Hazard identification is the process used to identify hazards.. ICAO Requirements. According to the FAA's Office of Safety Analysis, Since movement on an airport's surface involves coordination, While the movement of the aircraft is our primary concern, there remain some, Finally, while taxiing seems straight forward, it can also be an art, with, Once your engine has started you must be aware of what you're doing and keep a visual scan, your "flight" has begun, It may be required initially to tow the aircraft before engines are started to be safe, Steering is accomplished with rudder pedals and brakes, The pilot applies the rudder in the desired direction of turn and use the appropriate power or brake to control the taxi speed, To tighten the turn after full pedal deflection is reached, the brake may be applied as needed, When first beginning to taxi, conduct a check of braking effectiveness, Release the brakes, and add power as required to allow the airplane to begin moving forward, Reduce the power to idle and depress the top portion of one side, then the other, to confirm proper function and reaction of both brakes, Be mindful of the area around you (in front, behind, and to the sides), especially if you're in a congested ramp, Checking brakes individually is ideal, but checking them together, if required, will suffice, Apply pressure sufficiently enough to cause the airplane to abruptly dip, or to a full stop if desired, If unsatisfactory, bring the airplane to a stop and consider taxi maneuvers (such as a loop) to maintain position on the airfield, To verify steering, depress the rudder pedal in the direction of turn desired, Verify that the airplane responds properly to the rudder pedal input, Make sure to check the braking and steering for each position that may need to use them (i.e., both seats), More engine power may be required to start the airplane moving forward, or to start a turn, than is required to keep it moving in any given direction, When using additional power, the throttle should immediately be retarded once the airplane begins moving to prevent excessive acceleration, The rudder pedal should be held in the direction of the turn until just short of the point where the turn is to be stopped, Rudder pressure is then released or opposite pressure is applied as needed, When stopping the airplane, it is advisable to always stop with the nosewheel straight ahead to relieve any side load on the nosewheel and to make it easier to start moving ahead, During crosswind taxiing, even the nosewheel-type airplane has some tendency to weathervane, However, the weathervaning tendency is less than in tailwheel-type airplanes because the main wheels are located behind the airplane's center of gravity, and the nosewheel's ground friction helps to resist the tendency, The nosewheel linkage from the rudder pedals provides adequate steering control for safe and efficient ground handling, and normally, only rudder pressure is necessary to correct for a crosswind, Downwind taxiing usually requires less engine power after the initial ground roll is begun, since the wind is pushing the airplane forward, To avoid overheating the brakes and controlling the airplane's speed when taxiing downwind, the pilot must keep engine power to a minimum, Rather than continuously riding the brakes to control speed, it is appropriate to apply brakes only occasionally, Avoid resting toes on the brakes, resulting in unnecessarily dragging the brakes, Other than sharp turns at low speed, the throttle should always be at idle before the brakes are applied, When taxiing at appropriate speeds in no-wind conditions, the aileron and elevator control surfaces have minimal effect on directional control of the airplane, These controls should not be considered steering devices and should be held in a neutral position, The presence of moderate to strong winds and/or a strong propeller slipstream makes use of the aileron and elevator necessary to maintain control of the aircraft's roll/pitch while taxiing, This becomes apparent when considering the lifting action that may be created on the horizontal tail surfaces by either of those two factors, The elevator control in nosewheel-type airplanes should be held in the neutral position, while in tailwheel-type airplanes, it should be held in the full aft position to hold the tail down, When taxiing with a quartering tailwind, the elevator should be held in the DOWN position, and the upwind aileron, DOWN, Since the wind is striking the airplane from behind, these control positions reduce the tendency of the wind to get under the tail and the wing and to nose the airplane over, When taxiing with a quartering headwind, the wing on the upwind side (the side that the wind is coming from) tends to be lifted by the wind unless the aileron control is held in that direction (upwind aileron UP), Moving the aileron into the UP position reduces the effect of the wind striking that wing, thus reducing the lifting action, This control movement also causes the downwind aileron to be placed in the DOWN position, thus a small amount of lift and drag on the downwind wing, further reducing the tendency of the upwind wing to rise, Clearances are required prior to moving an aircraft or vehicle onto the movement area during the hours an, The movement area is normally described in local bulletins issued by the airport manager or air, These bulletins may be found in FSSs, fixed base operators offices, air carrier offices, and operations offices, A clearance must be obtained prior to taxiing on a runway, taking off, or landing during the hours an Airport Traffic Control Tower is in operation, When assigned a takeoff runway, ATC will first specify the runway, issue taxi instructions, and state any hold short instructions or runway crossing clearances if the taxi route will cross a runway, This does not authorize the aircraft to "enter" or "cross" the assigned departure runway at any point, In order to preclude misunderstandings in radio communications, ATC will not use the word "cleared" in conjunction with authorization for aircraft to taxi, ATC will issue an explicit clearance for all runway crossings, If a pilot is expected to hold short of a runway approach/departure (Runway XX APPCH/Runway XX DEP) hold area or ILS holding position (see FIG 2-3-15, Taxiways Located in Runway Approach Area), ATC will issue instructions, ARTCC clearances are relayed to pilots by airport traffic controllers in the following manner, Normally, an ATC IFR clearance is relayed to a pilot by the ground controller.
