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. In response, we have issued some transportation-related measures and guidance. These plans, which affect aircrew and vehicle operators, may incorporate additional lighting, markings, and procedures to control airport surface traffic. Why should an aircraft technician become familiar with standard light signals? And as The FAA is urging pilots to exercise increased vigilance when issued such clearances. 0000061214 00000 n Where can the standard aircraft taxi hand signals be found? Type I fluids may be applied to any aircraft when the anticipated time between deicing and take-off is minimal. Swing the prop with the flat of your hand and move back from the prop arc. Manage Settings Flying (and taxiing) should never be hurried. 0000057526 00000 n Captain may not hear or comprehend "hold short" clearances. Study the procedures in the Airplane Flight Manual. 0000019673 00000 n A taxi-in runway incursion is one where an aircraft which has just landed and which subsequently enters any active runway en route to parking, whether contrary to or in accordance with ATC clearance. 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 Simulation results indicate that total taxiing time is reduced by 243s after optimization and no taxiing conflict occurs. 0000051048 00000 n Keep a constant vigil on the state of your anti-icing protection during ground operations in active freezing precipitation.

The FAA and Transport Canada publish holdover time guidelines which are the times aircraft surfaces can be expected to remain protected from refreezing after anti-icing. Taxiing Aircraft As a general rule, only rated pilots and qualified airframe and powerplant (A&P) technicians are authorized to start, run up, and taxi aircraft. Under what conditions may automobile gasoline be used in an aircraft engine? It is a good practice to perform a foolproof test to be sure the pilot can see all signals. Limited operation may be allowed by the manufacturer. Pilots tend to taxi faster on runways than taxiways, exacerbating this problem. 0000249260 00000 n 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. Prior to starting a new engine or one that has been preserved for storage. Finally, it's suggested that the When applied hot, these fluids exhibit good deicing properties but provide very limited protection against refreezing in precipitation. contributed to the incident. aircraft in many precarious situations. But stop and consider this: the likelihood of a collision with another First, the initial call to Ground Control or Ramp Control Issues posing the greatest risk to Canada's transportation system. 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. Light signals may be used when taxiing an airplane without a radio or when a radio becomes inoperative on a tower controlled airport. 0000026526 00000 n Taxi slowly and stay farther away from other aircraft.

Learning to move the aircraft around on the ground can be just as difficult as learning steep turns. Jet inlets while engines are operating. All taxiing operations are performed in accordance with applicable local regulations. 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. Sign up for our FREE email newsletter. 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. "After deicing [was] started and the [deicing] Controlled movement of an airplane using its own power while on the ground. 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. require aggressive braking by the aircraft which could result in personnel injuries.

Well-developed ground deicing/anti-icing methodologies and procedures have been established for the airlines. Ground deicing is typically accomplished in several ways. If a pilot fails to verbalize the clearance, the other If clearance is not understood, ASK! Hazard identification is the process used to identify hazards.. ICAO Requirements. These accumulations may refreeze after take-off and impede control or gear movements later. {getWidget} $results={3} $label={recent} $type={list1}, Turboprop and Turbofan Engines Starting Procedures. What can be done as an operator or flight crew to What Does a Pilot Require To Remain Current in an Aircraft Requiring a Type Rating? Air transportation safety concerns and advisories. You're a solo pilot getting ready to take off from a busy airport. Type III fluids have a viscosity higher than Type I fluids but much lower than Type II or IV fluids. While a national effort is underway to reduce runway transgressions, startxref are designed for takeoffs and landings, they are not marked for taxiing. to minimize distractions during taxi-out? IF: You detect ice on your aircraft during the preflight inspection. Sort, search, and view reports from completed Transportation Safety Board investigations. These accidents and incidents can lead to property damage, injuries, and even death. B735, Newark NJ USA, 2006. Only if approved by the FAA, usually by the issuance of a Supplemental Type Certificate (STC). Reported one Captain: There are several reasons why the a. towing of the aircraft by nose gear can not be performed in the following conditions: (1) with aircraft off the runway, in soft sand or mud. 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. 0000248407 00000 n 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. to dented wing tips and excursions through the grass, either. Web Curator: GRC Web Team Stay up to date with the latest articles and selections from our archives. A primary distinguishing feature is their viscosity, which impacts both the holdover time and rotation speed. a deicing truck after beginning a premature taxi. Aiming a laser at an aircraft can cause a major accident. 0000250238 00000 n Runways are generally much wider than taxiways, and as a result seeing signs at their edge can be surprisingly difficult. To view the purposes they believe they have legitimate interest for, or to object to this data processing use the vendor list link below. 0000247480 00000 n 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 . 0000138970 00000 n caused by completing checklists, obtaining weight and balance information, and 0000050637 00000 n 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. pilots to call station operations to report "on the ground" after Can I taxi to the end of the ramp without permission, or do I call before releasing the brakes? The more viscous (thicker) the fluid, the longer the holdover time, but the higher the rotation speed required. The bookcases will have three shelves, in addition to the bottom and the top. When ready to start, call "CONTACT" and listen for the reply. Type II fluids have a higher viscosity than Type I fluids due to the addition of thickening agents. can help flight crews make that taxi operation safer: Any pilot knows the danger of a midair An increased chance of engine damage due to detonation, loss of engine power, and an increased probability of overheating. 0000248773 00000 n Hazards Associated With Flying at Night Presented by Name Transport Canada, System Safety. On occasion, however, minimum separation, particularly aircraft/vehicle separation is compromised. truck moved rearward no ground personnel were [visible to] the cockpit [crewmembers]. Multiple infractions should be considered grounds for suspension of airside driving privileges. 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. 0000049258 00000 n Security requirements when applying for a Foreign Air Operator Certificate. Subpart 703: Air Taxi. For anti-icing applications, this fluid may be applied undiluted. involve accidents, but the potential for a catastrophe accompanies each and A few ASRS reports indicate that basic as it may seem, a few ASRS reports indicate that some pilots have difficulty 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. No doubt these problems could be minimized if crews pilot must then challenge him/her to be sure that the clearance was understood. In fact, the worst accident in aviation history occurred due to a runway transgression This is an ideal place to put the airport diagram. Have a qualified person in the cockpit, check the brakes, call "SWITCH OFF" before moving the prop, and make sure you have a solid footing. report revealed: Here are a few suggestions that can Aviation safety recommendations. If this slush is not cleared prior to take-off, it may freeze in flight. xref Reporting accidents and unsafe acts or conditions, information for first responders. 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.
