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. 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. 0000151481 00000 n This will affect the promulgation of procedures and the required qualification for those occupying the flight crew seats on the aircraft during the manoeuvre.

Always conduct a pre-takeoff check for frozen contaminants just prior to take-off. %%EOF In the cockpit, complexity and workload will increase. This will allow you to focus on your route and communication. On occasion, however, minimum separation, particularly aircraft/vehicle separation is compromised. There are four types of deicing fluids. All taxiing operations are performed in accordance with applicable local regulations. Controllers - The ground controller is responsible for the safe and efficient movement of aircraft and vehicle traffic on the taxiways and aprons. Taxiing Technique Taxiing in a crosswind requires additional control inputs to keep the airplane's tires well planted and, in a strong crosswind, to prevent a wing or the tail of the airplane from being lifted by the wind. The more viscous (thicker) the fluid, the longer the holdover time, but the higher the rotation speed required. %PDF-1.6 % Safety, Ground Operations, and Servicing Flashcards | Quizlet truck moved rearward no ground personnel were [visible to] the cockpit [crewmembers]. Type I fluids may be applied to any aircraft when the anticipated time between deicing and take-off is minimal. Be careful with assumptions. Always have a plan when you begin to move and avoid distracted taxiing by getting your flight deck set before leaving the parking space. IF: You detect ice on your aircraft during the preflight inspection. In this section, we discuss the specific issues associated with ground operations in icing conditions. Tug operators - Tug operators have the additional responsibility of moving aircraft on and off gates as well as positioning aircraft from one location on the airfield to another. For general aviation, however, insufficient or improper ground deicing/anti-icing continues to cause several fatalities a year. to hold short of a particular runway or taxiway. 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. reduced aircraft clearance with ground equipment or obstacles. The first step in all thorough aircraft towing procedures is ensuring you're using the proper ground support equipment (GSE). The standard position for a signalman is slightly ahead of and in line with the aircrafts left wingtip. Place the aircraft in a heated hangar to melt frozen contaminants, followed by anti-icing to prevent refreezing of the melted contaminants when the aircraft is removed from the hangar. 0000061214 00000 n Taxiing Aircraft - Aircraft Systems Type III fluids have a viscosity higher than Type I fluids but much lower than Type II or IV fluids. Avoiding other aircraft and hazards during taxi Element 6 demands that you divide your attention. runway when another runway may be in use, and rushing. The idea is that the tower or ATC would see this abnormality and be able to intervene without the hi-jacker knowing that anyone had been tipped off. Responsible NASA Official: Peter Struk If Im not required to make any calls at a pilot-controlled field, should I announce that Im taxiing? Do I call ground before starting the engine? These include: inappropriate use of a restricted taxiway - some taxiways are restricted by wingspan. 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. If this slush is not cleared prior to take-off, it may freeze in flight. Reported one Captain: There are several reasons why the 0000152122 00000 n This same procedure should be practiced from after receipt of the clearance for landing until the landing and taxi activities are complete. hazards associated with beginning taxi without obtaining the "all clear" Write a solution to print the number of feet of 12-inch-wide boards that will Joe need to complete a bookcase, given the height and width.

First Officer stated: To be really effective the airport Definition. Maximum danger comes when two aircraft are present on the same active runway at the same time, despite any late awareness of this circumstance on the part of either the controller(s . that sometimes the First Officer calls for the taxi clearance while the Captain Stay up to date with the latest articles and selections from our archives. Seeking the most efficient flight - Episode 4 : sustainable taxiing on 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. FAA revises guidance for safely taxiing, towing aircraft failing to obtain a clearance before entering an area subject to control. One noted problem is Type I fluids have a high glycol content and a low viscosity; however, they are always applied diluted and heated.

What does the number 100 signify in 100LL aviation gasoline? aircraft taxiing hazards and remedy - coachinganimators.com Perhaps a study of the airport diagram prior to landing would help here by increasing d&&H`]0&+A$C,:fL`LLC salute from the ground crew. If frozen contaminants are present on the aircraft's critical surfaces they must be deiced and anti-iced (as appropriate) on the ground prior to take-off. Read reports on Transportation Safety Board investigations into specific aviation safety issues. No aircraft should attempt to take off with frost, snow, or ice adhering to wings, propellers, control surfaces, engine inlets, or other critical surfaces. Contact Ground Control or CTAF, as appropriate: State your aircraft identification, location, type of operation planned (VFR or IFR), if IFR, the point of first intended landing, if VFR, the cardinal direction, and that you have the appropriate ATIS/AWOS/ASOS code: Consider setting the heading bug/course indicator to display the takeoff direction. Type IV fluids are designed for aircraft with take-off rotation speeds of 100-110 knots or more, and may be applied when substantial time is anticipated between deicing and take-off. All rights reserved. Always taxi with your nosewheel on the centerline of the taxiway. FAA figures reveal that the percentage of pilot-caused runway transgressions "non-holding side.". obtain and read back any ground movement controller clearance prior to entering an area where clearance is required. Of course, ramps, taxiways, and runways covered with ice, snow, or slush will cause traction problems, as well as possible adhesion of ice and slush to critical airplane surfaces due to splashing. Ground will respond with your instructions: ATC will first specify the runway, issue taxi instructions, and then state any required hold short instructions, ATC is required to issue "hold shorts" or "cleared to cross" on any runway active or not in between you and your destination, Note that closed runways still required a cleared to cross call. Hazard Identification. When applied hot, these fluids exhibit good deicing properties but provide very limited protection against refreezing in precipitation. Contamination as small as 80-grit sandpaper can cause a 25% loss of wing lift. 0000012043 00000 n It is a good practice to perform a foolproof test to be sure the pilot can see all signals. B735, Newark NJ USA, 2006. Aviation enforcement and processes, corporate and non-corporate offenders. To prevent slush from contaminating control surfaces, taxi at low speeds and steer clear of prop and jet wash that can blow slush onto control surfaces. Commercial air services in Canada are defined in Part VII of the Canadian Aviation Regulations (CARs). Captain may not hear or comprehend "hold short" clearances. No doubt these problems could be minimized if crews would place the airport diagram chart where it could be easily referred to during rushing and "the lack of coordination between the cockpit and ground personnel" Air transportation safety concerns and advisories. 0000247639 00000 n These fluids provide better protection against refreezing than Type I fluids. Its nothing like driving a car, and can be frustrating zigzagging down the taxiway or making turns too sharp or shallow until youve mastered the skill.
