Some aircraft are equipped with chart holder "clipboards" Contamination as small as 80-grit sandpaper can cause a 25% loss of wing lift. Learning to move the aircraft around on the ground can be just as difficult as learning steep turns. A simulation is conducted based on a practical setting of 9 flights on runway 02L at a central-south airport. %PDF-1.6 % For anti-icing applications, this fluid may be applied undiluted. PDF Taxiing for Takeoff - ASRS 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 . Light signals may be used when taxiing an airplane without a radio or when a radio becomes inoperative on a tower controlled airport. If Im not required to make any calls at a pilot-controlled field, should I announce that Im taxiing? The standard position for a signalman is slightly ahead of and in line with the aircrafts left wingtip. Type III fluids were formulated for use on small commuter-type aircraft with take-off rotation speeds that exceed approximately 60 knots. 0000050358 00000 n The FAA is urging pilots to exercise increased vigilance when issued such clearances. Taxi-in Runway Incursions | SKYbrary Aviation Safety 0000005441 00000 n 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. In fact, more than a few aviation safety incidents or near misses have occurred simply while on the ground during a ground or taxiing procedure. aircraft taxiing hazards and remedy. runway when another runway may be in use, and rushing. in this data set occurred because crews became disoriented while taxiing. 0000019673 00000 n 0000152436 00000 n landing? 0000050056 00000 n Still looking for something? 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. Type II fluids are designed for use on an aircraft with take-off rotation speeds of 100 to 110 knots or more and may be applied when substantial time is anticipated between deicing and take-off. While a national effort is underway to reduce runway transgressions, The air traffic controller has given you a route to follow to your assigned runway . to a runway transgression. The AC now addresses aircraft being taxied . at Tenerife, Canary Islands. First Officer write down the taxi clearance and holding instructions. The filler openings must be marked with the fuel grade and the word "AVGAS". obtain and read back any ground movement controller clearance prior to entering an area where clearance is required. Vehicle operators - It is imperative that vehicle operators be properly trained, tested and authorised for ramp and taxiway operations. Hazards Associated With Flying at Night Presented by Name Transport Canada, System Safety. 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. 0000249483 00000 n Can I taxi to the end of the ramp without permission, or do I call before releasing the brakes? 0000002743 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. 0000101385 00000 n Now then, Even though FBO personnel may deice your aircraft, you are ultimately responsible for ensuring that it was done appropriately. Some of our partners may process your data as a part of their legitimate business interest without asking for consent. endstream endobj startxref Although the act of taxiing an aircraft to hold short of a particular runway or taxiway. Here are the top 5 mistakes I see routinely at our home airport. According to the Airmen's Information Whenever these thickened fluids are applied, be sure to follow the manufacturer's recommended procedures for your aircraft, including procedures for operation of the engines and auxiliary power unit. No doubt these problems could be minimized if crews Read about Transport Canada's responses to Transportation Safety Board recommendations for aviation safety. Pilots tend to taxi faster on runways than taxiways, exacerbating this problem. The aircraft may be treated with deicing/anti-icing fluids, placed in a heated hangar then sprayed with anti-icing fluid, or deiced via mechanical means with brooms, rubber scrapers, or forced air. 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 . 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. By enabling aircraft to turn off their engines during taxiing operations, the vehicle allows a reduction of noise emission and a reduction of fuel-burn and CO2 emissions up to 85% while improving air quality around airports as well. In this article Think about what distance it may take to roll to a stop if you were forced to pull the power and adjust your speed so this could be accomplished in a reasonable distance. 0000152122 00000 n Describe the precautions that should be taken to protect life and property while starting and running an aircraft engine. of the two hundred twenty-four runway transgressions reported in 1991, forty-one Chapter 7 - Aircraft Structural Materials, Ch 017 - Aircraft Airworthiness Inspection, Ch 014 - Cabin Atmosphere Control Systems, Fundamentals of Engineering Economic Analysis, David Besanko, Mark Shanley, Scott Schaefer. 0000057526 00000 n Become throughly trained.

Table 1 contains the standard taxi light signals used by control towers to control and expedite the taxiing of aircraft. Planes use taxis to __________________________. Hazard Identification. we hope to offer a few practical suggestions towards eliminating future taxi-related contributed to the incident. A couple of ASRS reports illustrate six inches apart. Following a runway transgression one ASRS reporter offered: Because of the lack of these markings The first step in all thorough aircraft towing procedures is ensuring you're using the proper ground support equipment (GSE). 0000249139 00000 n All rights reserved. that sometimes the First Officer calls for the taxi clearance while the Captain A laser is not a toy. the passenger count. Some taxi-related . Description. 0000248922 00000 n Next, whenever a "hold short" Limited operation may be allowed by the manufacturer. Most instructors teach that the proper speed for a taxi is nothing more than a brisk walk. 0000152353 00000 n Ground Collision ( GCOL) - a collision that occurs while an aircraft is taxiing to or from a runway in use. "non-holding side.". Please check if any of these measures apply to you. 0000012300 00000 n Taxiing is the movement of an aircraft on the ground, under its own power, in contrast to towing or pushback where the aircraft is moved by a tug, The aircraft usually moves on wheels, but the term also includes aircraft with skis or floats, An airplane uses taxiways to taxi from one place on an airport to another; for example, when moving from a can be taken before leaving the ramp. would place the airport diagram chart where it could be easily referred to during 0000061214 00000 n Type IV fluids offer the best protection against refreezing. Having correct crosswind input on your control surfaces will also help you maintain the centerline. 0000002942 00000 n We welcome your comments on flyingmag.com. All taxiing operations are performed in accordance with applicable local regulations. 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.
