No persons were injured and minor aircraft damage occurred. 0000138900 00000 n obtain and read back any ground movement controller clearance prior to entering an area where clearance is required. Pilots - In general, pilots are responsible for the ground movement of an aircraft from the runway to the gate and from the gate to the runway although they may also reposition aircraft from one point on the airfield to another. 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. that he became distracted when a Flight Attendant entered the cockpit to give One noted problem is aircraft-aircraft collisions or near collisions - collisions can result from: failure to follow taxiway centreline guidance failure to stop prior to a stopbar taxiing at speeds unsuited to the conditions or level of congestion taxiway deviation whilst trying to manoeuvre to "squeeze" past another aircraft. Five hundred and eighty-three souls perished in 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. Table 1 contains the standard taxi light signals used by control towers to control and expedite the taxiing of aircraft. 0000247480 00000 n Continue searching. If you cannot get through, please contact us by email. In response, we have issued some transportation-related measures and guidance. basic as it may seem, a few ASRS reports indicate that some pilots have difficulty In the cockpit, complexity and workload will increase. Air transportation safety concerns and advisories. No aircraft should attempt to take off with frost, snow, or ice adhering to wings, propellers, control surfaces, engine inlets, or other critical surfaces. 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. As previously stated, to ensure efficient and safe airport ground operations, separation between aircraft or between aircraft and vehicular traffic must be maintained and optimised. d&&H`]0&+A$C,:fL`LLC If misjudged, this could result in a wingtip striking the tail of the stopped aircraft or it could compromise clearance between obstacles or other aircraft and the wingtip opposite the stopped aircraft, taxiway configuration - converging taxiways can potentially lead to reduced or compromised clearance, especially where they cross. Other aircraft, vehicles, personnel, and other obstacles. You're a solo pilot getting ready to take off from a busy airport. 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 . are both monitoring that frequency. This is an ideal place to put the airport diagram. 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. 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. Always conduct a pre-takeoff check for frozen contaminants just prior to take-off. Type III fluids have a viscosity higher than Type I fluids but much lower than Type II or IV fluids. Resistance to the prop turning indicates a possible hydraulic lock in at least one of the cylinders. And its nothing to be ashamed of because its common and taxiing is not natural. FAA's updated "advisory circular" includes newly defined items such as airport operations areas and non-movement areas, and offers guidance for towered airports regarding non-pilot workers and equipment in the runway safety area. Deicing for Safe Taxiing - Flight Safety Foundation 0000138093 00000 n Express the position vector r in Cartesian vector form; then determine its magnitude and coordinate direction angles.

Read about Transport Canada's responses to Transportation Safety Board recommendations for aviation safety. 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. 7 ways to minimize aircraft towing damage - RTITB Read recommendations for advancing aviation safety resulting from Transportation Safety Board investigations. In a number of cases pilots have taxied beyond their turnoff point because they saw what was on a distant sign too late. Can checklists be rewritten Let's review some of the things which contributed to the incident. Privacy Policy and Important Notices These accumulations may refreeze after take-off and impede control or gear movements later. that 1977 accident.

Controlled movement of an airplane using its own power while on the ground. times greater than the chance of striking another aircraft in flight. Oil seeps by the piston rings and accumulates in the combustion chamber of lower cylinders. Only use Type II, III, & IV fluids with the approval of the aircraft manufacturer. %%EOF Study the procedures in the Airplane Flight Manual. 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. IF: You detect ice on your aircraft during the preflight inspection. Windy Flight Operations - AOPA - Aircraft Owners and Pilots Association Page updated: September 27, 2016. Because runway surfaces 190 91 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. hS]HSq?cs:gY0C_cv?#$2#!9k!bAKX(I}F_TufD{{~= H x4E^b17 9M}q)Rs6Rau`{kUbH \# lDa2:z'{isIr^;cu"5>Ze[=(Hn(j K.t]OK These fluids provide better protection against refreezing than Type I fluids. An increased chance of engine damage due to detonation, loss of engine power, and an increased probability of overheating. 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. (a) It is difficult to extinguish a fire on a crude oil . Having precise control while taxiing will help as you manage directional control during the takeoff. Investigations and recommendations by the Transportation Safety Board, reporting accidents or unsafe conditions. "For an A320 with 3 take-off per day from Paris Roissy . Several pilots complained that cockpit 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.
