AC 150/5210-20A - Ground Vehicle Operations to include Taxiing or The controversy over restricting the use of aircraft deicing fluid at airport gates started with EPA's proposal to exempt the associated wastewater from new collection and treatment requirements by limiting deicing for safe taxiing to the use of a maximum of 25 gal (95 L) of fluid. Other aircraft, vehicles, personnel, and other obstacles. Same rule goes for taxiing in as taxiing out. 0000152491 00000 n What procedure should be followed prior to starting a large radial engine to detect and/or prevent a hydraulic lock in the cylinders? 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. Type III fluids were formulated for use on small commuter-type aircraft with take-off rotation speeds that exceed approximately 60 knots. Perhaps a study of the airport diagram prior to landing would help here by increasing %PDF-1.6 % situational awareness. Because runway surfaces "non-holding side.". In this section, we discuss the specific issues associated with ground operations in icing conditions. can arise when pilots turn off onto another runway after landing. contribute to taxi distractions. These fluids provide better protection against refreezing than Type I fluids. Reproduction in whole or in part without permission is prohibited. Therefore Damaged or defective equipment is dangerous, often resulting in injuries to personnel or damage to equipment and aircraft, so all equipment used for towing aircraft should undergo regular maintenance and, crucially, it should be inspected at the beginning of each shift. 0000010966 00000 n Paraphrasing FAR 121.542: "No certificate holder loading flight management computers. WHY: Mixtures of water, slush and deicing fluid may accumulate in aerodynamically quiet areas such as gaps surrounding control surfaces or in the landing gear. Several Driving infractions should be investigated and additional training provided where appropriate. in this data set occurred because crews became disoriented while taxiing. A couple of ASRS reports illustrate produce significant hazards to flight. Taxi and take-off in icing conditions present several unique hazards.

Become throughly trained. What Does a Pilot Require To Remain Current in an Aircraft Requiring a Type Rating? Spray the aircraft with heated water if the temperature is -3C (27F) or warmer, immediately followed by a second anti-icing treatment of heated Type I fluid heated to nominally 60C (140F) at the nozzle. This ensures adequate lubrication on initial startup. 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 landing? the usual cues such as holding lines for intersecting runways probably will 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. Most instructors teach that the proper speed for a taxi is nothing more than a brisk walk. is taxiing as routine as you may have thought it was. Ground deicing is typically accomplished in several ways. IF: You detect ice on your aircraft during the preflight inspection. (2) with main or nose gear having two flat tires on one axle. Commercial air services in Canada are defined in Part VII of the Canadian Aviation Regulations (CARs). There are four different categories, based on an aircraft's takeoff weight, the type of work being performed and the number of passengers it is configured to carry.

What markings are required for a piston engine powered airplane? 0000049400 00000 n 0000005695 00000 n 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. Airport operators are responsible for setting safety policies and procedures for workers who transport aircraft. List at least three possible hazards associated with the ground operations of aircraft. 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. 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. What does the number 100 signify in 100LL aviation gasoline? Hazard Identification. Copyright 2023 Flying Media. What is the most generally used knot for tying down small aircraft? Can checklists be rewritten They will be addressed at two levels; operations less than 1,200 feet RVR to 500 feet RVR and operations less than 500 feet RVR, Specific lighting systems and surface markings may be found in Paragraph 2-1-11, Taxiway Lights, and Paragraph 2-3-4, Taxiway Markings, When low visibility conditions exist, pilots should focus their entire attention on the safe operation of the aircraft while it is moving. These 7 ways to minimize aircraft towing damage - RTITB 0000261155 00000 n 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.
