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 same procedure should be practiced from after receipt of the clearance for landing until the landing and taxi activities are complete. Can weight and balance information Turning props, rotors, prop or jet blast and inlet areas. Driving infractions should be investigated and additional training provided where appropriate. Read recommendations for advancing aviation safety resulting from Transportation Safety Board investigations. PDF Taxiing for Takeoff - ASRS taxi. 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. can help flight crews make that taxi operation safer: Any pilot knows the danger of a midair 0000011606 00000 n This could affect the handling qualities of your aircraft.

If an engine induction fire occurs while starting a reciprocating engine, what procedure should be followed to extinguish the fire? Spray the aircraft with Type I fluid that is diluted and heated to nominally 60C (140F) at the nozzle. Large transport vs. small aircraft operations. Five hundred and eighty-three souls perished in MITRE is enhancing aviation's safety toolkit with an application designed to prevent pilots from taxiing onto a runway without permission, a scenario that poses an enormous collision risk. Hq4XDAs`$RxqP4S*i3iL7V M@06H2h3g0r1>gf;7F+32d3. As pilots upgrade into larger aircraft, taxiing may be accomplished by the use of a tiller, vs. rudder pedals; Still looking for something . Paraphrasing FAR 121.542: "No certificate holder Avoiding other aircraft and hazards during taxi Element 6 demands that you divide your attention. What is air-taxi? startxref This article examines collisions and near collisions whilst aircraft are on the airport manoeuvring areas inclusive of taxiways and ramp areas. 0000249761 00000 n Recently approved changes to several Annexes of the Chicago Convention introduce harmonised requirements for the implementation and operation of safety management systems (SMS) by aircraft operators and aviation service providers. Taxiway Collisions | SKYbrary Aviation Safety involve accidents, but the potential for a catastrophe accompanies each and Is it permissible to use avgas in a turbine engine? When taxi instructions are received from the controller, pilots should always read back: Any instruction to hold short of a specific runway or line up and wait, Controllers are required to request a read-back of runway hold short assignment when it is not received from the pilot/vehicle, The control tower also issues bulletins describing areas where they cannot provide service due to non-visibility or other reasons, This is usually done through ATIS/AWOS remarks, Begin taxi, monitoring ground frequency until into the run-up area, Exit the runway without delay, at the first available taxiway, or as instructed, All parts of the aircraft must be across the hold short line to be considered off the runway, When issuing taxi instructions to any point other than an assigned takeoff runway, ATC will specify the point to taxi to, issue taxi instructions, and state any hold short instructions or runway crossing clearances if the taxi route will cross a runway, ATC is required to obtain a read-back from the pilot of all runway hold short instructions, An essential requirement in conducting safe taxi operations is where the pilot maintains situational awareness, Depending on the airport, parking, ramp, and taxiways may or may not be controlled, The pilot should make themselves familiar with the parking, ramp, and taxi environment, Especially at unfamiliar airports, review, and have available the, If routing is expected to be complex, consider listening to ground control, if able, on, The pilot must be vigilant of the entire area around the airplane to ensure that the airplane clears all obstructions, If, at any time, there is doubt about a safe clearance from an object, the pilot should stop the airplane and check the clearance, It may be necessary to have the airplane towed or physically moved by a ground crew, When taxiing, the pilot's eyes should be looking outside the airplane scanning from side to side while looking both near and far to assess routing and potential conflicts, especially at intersections, It is helpful to use internal callouts to accomplish this task: ", The primary requirements for safe taxiing are positive control, the ability to recognize any potential hazards in time to avoid them, and the ability to stop or turn where and when desired, without undue reliance on the brakes, The pilot should accurately place the aircraft centered on the taxiway at all times, Some taxiways have above ground taxi lights and signage that could impact the airplane or propellers if the pilot does not exercise accurate control, When taxiing, the pilot must slow down before attempting a turn, Sharp high-speed turns place undesirable side loads on the landing gear and may result in tire damage or an uncontrollable swerve or a ground loop, Swerves are most likely to occur when turning from a downwind heading toward an upwind heading, In moderate to high-wind conditions, the airplane may weathervane increasing the swerving tendency, Good operating practice dictates that pilots acknowledge all runway crossing, hold short, or takeoff clearances unless there is some misunderstanding, at which time the pilot should query the controller until the clearance is understood, NOTE: Air traffic controllers are required to obtain from the pilot a read-back of all runway hold short instructions, Also, without clearance to cross a runway, you should never cross a red sign-think of it as a stop sign, Pilots operating a single pilot aircraft should monitor only assigned ATC communications after being cleared onto the active runway for departure. contribute to taxi distractions. One noted problem is The air traffic controller has given you a route to follow to your assigned runway . 2068 0 obj <> endobj poses its own set of potential safety-related problems. aircraft taxiing hazards and remedy - coachinganimators.com Watch for obscured surface markings; snow and slush can obscure pavement markings and create a runway incursion hazard or cause you to taxi off the taxiway and onto a soft embankment. pilots to call station operations to report "on the ground" after Hazard Identification | SKYbrary Aviation Safety Jet exhaust or propeller blast. 0000261155 00000 n Type IV fluids offer the best protection against refreezing. This is a critical safety issue and a legal requirement. a runway transgression occurred because the Captain did not hear the clearance All taxiing operations are performed in accordance with applicable local regulations. 0000152491 00000 n decrease the threat of runway transgressions? And as Taxi-in Runway Incursions | SKYbrary Aviation Safety Checklists and nonessential communication should be withheld until the aircraft is stopped and the brakes set, If the pilot is unfamiliar with the airport or for any reason confusion exists as to the correct taxi routing, a request may be made for progressive taxi instructions which include step-by-step routing directions, Progressive instructions may also be issued if the controller deems it necessary due to traffic or field conditions (for example, construction or closed taxiways), The need for progressive taxi can be mitigated by proper preflight planning and having airport diagrams handy, The use of takeoffs-and-landings/taxi lights is an effective means of illuminating surface hazards during taxi movements at night and alerting all concerned of an aircraft's presence/position in flight, Lights may be turned off under certain conditions whereby safety is still the primary focus, Examples would be when taxiing toward or yielding too other aircraft or in a ramp setting with adequate ambient lighting, A low visibility taxi plan will exist giving the pilot additional instructions when the RVR is less than 1,200' and again in operations less than 600' RVR, Do not switch frequencies while taxiing, in case ground needs to contact you, Auto-switch tower when approaching the hold short to monitor traffic, If you have just cleared a runway and are looking to taxi, call with intentions as appropriate, Exit without delay at the first available taxiway or as instructed, Personnel must always be aware of the dangers associated with moving surfaces, Rotor wash created by the blades of a rotary-winged aircraft or thrust from the exhaust section of a fixed-winged aircraft may cause severe personnel injury, The proper safety equipment must always be worn when working on flight decks and flight lines, Aircraft with conventional landing gear (tailwheel/draggers) aircraft have special considerations that are unique to them, The center of gravity of a tailwheel aircraft is behind the cockpit which can cause instability during taxi, Make smooth inputs on the controls and be mindful that the center of gravity is not allowed to get to the side of the aircraft with enough momentum to carry it around, Once a ground loop has started there is no way to get out of it until it has run its course, In the interest of avoiding obstacles or staying on a paved surface however, differential breaking with the inside break will tighten the loop, While speed can be a contributing factor to ground loops, it is also necessary to maintain positive control, If the aircraft is taxiing too fast, and breaks are applied too firmly, the tail can raise causing the tailwheel to lose effectiveness while simultaneously causing the propeller to move closer to the ground, If the tail comes up high enough, the pilot may experience a propeller, or "prop" strike, Flight Personnel are utilized on many aircraft ramps to direct traffic in an orderly fashion in accordance with local procedures [, Flashing your landing/taxi lights at the marshaller will help signal when you are ready, especially at night, Likewise, don't blind them with the light, turn it off until clear of the marshaller, Night: Flashlight moved vertically up-and-down repeatedly, Night: Flashlight moved horizontally back-and-forth repeatedly, Day: One arm pointing up with the other pointing down, Night: Same signal as day, but with lights, Day: Point to engine OR indicate engine number with fingers while making horizontal circular motion above head with other, Day: Move arms outward with thumbs pointed outward, Day: The direction of turn is indicated by that arm pointing downward while the other gestures to come closer, Day: Flagman holds hands in air to catch the pilot's attention, Day: With palms facing down, arms are moved up and down at side, Day: Move arms inward with thumbs pointed inward, Day: A cutting motion with a flat palm is made across neck, Day: Hand cupped behind ear as if listening, Day: Hand waved back and forth in an erasing motion in front of face, with palm turned forward, Night: Trace of letter N, given by external light, Fingers held vertically indicate 1 through 5, Fingers held horizontally indicate 6 through 9, Forgetting to remove a tie-down or chocks prior to attempting movement, Improper aileron deflection, particularly after turning, Taxiing with a power setting that requires controlling taxi speed with the brakes, To determine that the applicant exhibits satisfactory knowledge, risk management, and skills associated with safe taxi operations, including runway incursion avoidance, References: FAA-H-8083-2, FAA-H-8083-3, FAA-H-8083-25; POH/AFM; AC 91-73; Chart Supplements; AIM, The NTSB determines the probable cause(s) of this accident to be: The student pilot's failure to maintain a visual look out while transitioning from the active runway to a taxiway resulting in an on-ground collision with a taxiway sign, The NTSB determines the probable cause(s) of this accident to be: The pilot's failure to maintain clearance from a parked airplane during taxi operations at night, Taxiing is part of every flight, and it should be part of planning, ATC clearances or instructions pertaining to taxiing are predicated on known traffic and known physical airport conditions, Since "the pilot-in-command of an aircraft is directly responsible for, and is the final authority as to, the operation of that aircraft" the pilot should obtain clarification of any clearance or instruction which is not understood, Therefore, it is important that pilots clearly understand the clearance or instruction, Although an ATC clearance is issued for taxiing purposes, when operating in accordance with the CFRs, it is the responsibility of the pilot to avoid collision with other aircraft, In addition to conducting taxi operations as a maneuver, pilots must also be familiar and comply with all, Pay attention when in a movement area and be cognizant of expectation bias, that is having a belief you are prepared for what lies ahead and not pay attention to what is different, such as an atypical location for a runway hold position marking, When it comes to hand and arm signals, variations may exist, If any questions come up while taxiing, stop, and try to get clarification before proceeding, When taxiing and determining wind direction, make sure you account for the resultant wind, Consider the use of heading bugs to remember where the wind is coming from and/or to remember the assigned takeoff direction, Consider the use of a heading indicator course indicator to supplement, While it is best practice to always apply taxi corrections, regardless of wind velocity, it is imperative these corrections be used any time you can feel even the slightest movement in the yoke, During ground operations, jet blast, prop wash, and rotor wash (types of thrust stream turbulence) can cause damage and upsets if encountered at close range, Pilots should consider the effects of jet blast, prop wash, and rotor wash on aircraft, vehicles, maintenance equipment, and open structures (i.e., hangars) during ground operations, Additional resources are available through tools such as the FAA's, Remember when parking, to park in such a way to avoid inevitable jet blast (especially from larger aircraft), use tiedowns, and install control locks or covers as appropriate, Don't be afraid to practice if you need it, Different aircraft require different skills and even experienced pilots in, As pilots upgrade into larger aircraft, taxiing may be accomplished by the use of a tiller, vs. rudder pedals. this author, most involved unauthorized runway transgressions. High noise levels that might cause hearing damage. The marking requirements for oil tank filler openings are specified by FAR 23.1157. For aircraft that aren't so equipped, a piece of masking tape in the window Type I fluids have a high glycol content and a low viscosity; however, they are always applied diluted and heated. Type I fluids may be applied to any aircraft when the anticipated time between deicing and take-off is minimal.
