Description. Even though most of the hazards associated with flying at night have been known in the aviation industry for many years, these types of accidents continue to occur, which would indicate that pilots' knowledge or awareness of these hazards is still very low. An airport is a complex interface between the air and the ground environments, where access must be controlled and separation between aircraft or between aircraft and vehicular traffic must be maintained and optimised. Manual: "When approaching the holding Under what conditions may automobile gasoline be used in an aircraft engine? FAA figures reveal that the percentage of pilot-caused runway transgressions You might sound weird, but it beats getting a verbal lashing from the tower. The FAA is urging pilots to exercise increased vigilance when issued such clearances. Deicing for Safe Taxiing - Flight Safety Foundation in this data set occurred because crews became disoriented while taxiing. 0000249761 00000 n 0000050056 00000 n Aircraft performance, ground and flight visibility, and friction between aircraft tires and airport surfaces can be severely reduced. Planes use taxis to __________________________. The number one violation we see at our airport is aircraft taxiing too fast. pilots should be particularly alert when taxiing on runways. 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. Transport Canada is closely monitoring the COVID-19 situation. Type I fluids have a high glycol content and a low viscosity; however, they are always applied diluted and heated. Aircraft taxiing route planning based on airport hotspots Description. situational awareness. Now then, Even something as routine as taxiing Name at least three possible hazards that may be encountered during typical ground operations, such as during engine run-up or taxiing? This could affect the handling qualities of your aircraft. First, the initial call to Ground Control or Ramp Control At busy locations, however, pilots may be instructed by the ground controller to "contact clearance delivery" on a frequency designated for this purpose, No surveillance or control over the movement of traffic is exercised by this position of operation, Taxiing checklists are sometimes specified by the AFM/POH, and the pilot must accomplish any items that are required, If there are no specific checklist items, taxiing still provides an opportunity to verify the operation and cross-check of the flight instruments, Additionally, the heading indicator should not precess more than 3 in 15 minutes, These checks can be accomplished on conventional mechanical instrumented aircraft or glass cockpits, Do not perform any items while taxiing that prevent you from safely operating the aircraft, Complete all checklists required before taxi, Consider setting the heading bug/course indicator to display where the winds are coming from, Contact Clearance Delivery, as appropriate.

Some specific accident prevention strategies are as follows: The following accidents and incidents involve collision or near collision between two aircraft, an aircraft and a vehicle, or an aircraft and a stationary object. 0000049400 00000 n Even though FBO personnel may deice your aircraft, you are ultimately responsible for ensuring that it was done appropriately. For anti-icing applications, this fluid may be applied undiluted. 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. 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. aircraft, vehicle, pedestrian, or other object while taxiing is about three Not so obvious is how handling may be affected by deicing fluids. A laser is not a toy. Ignition occurs with an excessively rich mixture, leading to a rapid temperature rise that can exceed the exhaust gas temperature limit. when pilots were instructed to taxi on inactive runways. Read reports on Transportation Safety Board investigations into specific aviation safety issues. has increased since 1988.

Proper effective scanning for other aircraft, surface vehicles, or other objects should be continuously exercised in all cases, At those airports where the U.S. Government operates the control tower and ATC has authorized noncompliance with the requirement for two-way radio communications while operating within the Class B, Class C, or Class D surface area, or at those airports where the U.S. Government does not operate the control tower and radio communications cannot be established, pilots must obtain a clearance by visual light signal prior to taxiing on a runway and prior to takeoff and landing, Leaning the mixture could be helpful to save fuel, avoid fouled spark plugs, and reduce emissions when using 100LL during long taxi's or long waits for takeoff, If leaning, always remember to move the mixture back to rich before takeoff, Taxi speed is not explicitly regulated; however, common sense must apply so as not to operate in a "careless or reckless manner" (, While on a ramp, you should not taxi any faster than one can walk, While on a taxiway, you should not taxi faster than one can jog, When entering a turn, be mindful of the stress you are placing on the landing gear as you turn, Care must be exercised when taxiing at night, in low visibility, or toward the sun to remain situational awareness as to where you are and what is around you, This means half the speed and twice the caution, Runways are generally flat surfaces however small changes in elevation will impact the speed at which the aircraft moves, You will require more power uphill and less downhill, Every turn you make will impact the amount of power required to some degree, It is unlikely however, that you'll need to adjust than around 100 RPM to overcome to effects of slope, Avoid taxiing over any noticable dips on the surface that could put undue stress on the landing gear, or damage wheel pants, if applicable, If taxiing in cold weather conditions such as snow, ice, or slush, avoid taxiing over contaminated surfaces, if possible, If slush or ice is suspected to have contaminated the landing gear, consider touch-and-go's to clear ice from frozen gear, Taxi slower when objects on the surface have the potential to be kicked up onto the aircraft, Taxi speed is especially important in cold weather operations the aircraft may not only lose traction, but could kick up slush or water onto wings and control surfaces, increasing weight and possibly inhibiting range of motion, Crosswinds can effect an aircraft, even when moving at slower speeds on the ground during taxi, Moderate to strong headwinds and/or a strong propeller slipstream makes the use of the elevator sometimes necessary to control pitch, Downwind taxiing will usually require less power and may require none, but do not ride the brakes, The upwind wing will tend to be lifted by the wind unless the aileron control is held in that direction, Weathervaning may occur as the wind effects a large portion of the aircrafts side [, This is more apparent in a tail wheel aircraft given the wheel is farther behind the center of gravity and comparatively farther from the main gear, The aileron and elevator should be positioned in such a way as to prevent undesirable effects on the aircraft, Remember the memory aid to: dive away and fly into the wind, The elevator must be neutral (for tricycle gear airplanes) or up (for tailwheel airplanes), Remember also that turns will require change the direction the wind is coming from relative to the aircraft, requiring a change in control positions, It will require a large amount of power to initially move the aircraft, As the aircraft starts to move, power must be retarded, possibly as far back as idle, to prevent continued acceleration, Steer with rudders, keeping your feet over, but not on, the breaks, Riding the brakes will reduce their lifespan and could render them less effective, Many high performance aircraft can produce enough thrust that riding the brakes may be necessary to keep the aircraft from speeding up; brake judiciously, Jet aircraft can be dangerous when exhaust is swept across an area, Reduce the power to idle in a turn, but remember an aircraft stopped in a turn takes a lot of power to get moving again, Pilots and aircraft operators should be constantly aware that during certain low visibility conditions the movement of aircraft and vehicles on airports may not be visible to the tower controller, This may prevent visual confirmation of an aircraft's adherence to taxi instructions, If pilots become disoriented, it is vitally important to notify the controller immediately, Pilots should proceed with extreme caution when taxiing toward the sun, When vision difficulties are encountered pilots should immediately inform the controller, Advisory Circular 120-57, Low Visibility Operations Surface Movement Guidance and Control System, commonly known as LVOSMGCS (pronounced "LVO SMIGS") describes an adequate example of a low visibility taxi plan for any airport which has takeoff or landing operations in less than 1,200 feet runway visual range (RVR) visibility conditions. 0000101315 00000 n Towards a more sustainable ground traffic management.
