What is meant by the term "Hot Start" when starting a jet engine? we hope to offer a few practical suggestions towards eliminating future taxi-related Fire, during engine starting. 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. You might sound weird, but it beats getting a verbal lashing from the tower. B735, Newark NJ USA, 2006. For anti-icing applications, this fluid may be applied undiluted. Type III fluids were formulated for use on small commuter-type aircraft with take-off rotation speeds that exceed approximately 60 knots. Same rule goes for taxiing in as taxiing out. Aviation accidents and investigations - Transport Canada 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. others reported that the lack of conspicuous taxiway markings and signs contributed It refers to the lean mixture performance number (or octane rating) of the fuel. hazards associated with beginning taxi without obtaining the "all clear" We and our partners use data for Personalised ads and content, ad and content measurement, audience insights and product development.

Aiming a laser at an aircraft can cause a major accident. 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. Whether you're using aircraft recovery dollies or towbarless tugs, it's important to use the right GSE (with the right towing capacity) for the job. Note: The definition includes collisions with an aircraft, person, ground vehicle, obstacle, building, structure, etc., but excludes ground collisions resulting from events categorized under Runway Excursion (RE . 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. 0000194210 00000 n No doubt these problems could be minimized if crews 1 / 32 Controlled movement of an airplane using its own power while on the ground. Its normally the pilot who requested a quick turn from the FBO after jamming on the brakes to make the mid-field turn off. Air transportation safety concerns and advisories. pilots to call station operations to report "on the ground" after hbbd```b``" R} 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. 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. Given that the student was going solo, it made for a fun radio conversation. In fact, more than a few aviation safety incidents or near misses have occurred simply while on the ground during a ground or taxiing procedure. Oil seeps by the piston rings and accumulates in the combustion chamber of lower cylinders. to the taxiway and consist of two continuous and two dashed lines, each spaced Operators should: ensure daily inspection for their vehicle is complete and that beacon/hazard lights are operating when the vehicle is airside, operate their vehicle safely and in accordance with all company and airport rules, obey all "rules of the road" inclusive of speed limits, stop signs and right-of-way guidance. The articleOn-Gate Collisionsprovides insight into aircraft collisions occurring whilst on, entering or leaving an assigned gate. For anti-icing applications, this fluid is applied undiluted. Think about what distance it may take to roll to a stop if you were forced to pull the power and adjust your speed so this could be accomplished in a reasonable distance. Continue cranking the engine to start it and suck the fire into the engine. the Airmen's Information Manual states that when clearing a runway after landing, Limited operation may be allowed by the manufacturer. A technical crew was repositioning the aircraft in visual meteorological conditions during the occurrence. Stay up to date with the latest articles and selections from our archives. Also, ensure that the prop or jet blast doesn't blow into hangars or other airplanes, and have a fire guard nearby. Keep a constant vigil on the state of your anti-icing protection during ground operations in active freezing precipitation. %PDF-1.4 % 0000138900 00000 n runway when another runway may be in use, and rushing. Several The deicing fluids and some of their characteristics are identified in the chart and the "Related Information" links on this page. While a national effort is underway to reduce runway transgressions, Student pilots normally dont violate this one as they tend to be slow and methodical. If clearance is not understood, ASK! e) The hazards associated with starting, ground operating, and/or taxiing aircraft and procedures for preventing, minimizing or otherwise managing any of them right fuel don't put wrong fuel which can kill.airplane grounded and to the truck. are designed for takeoffs and landings, they are not marked for taxiing. Still looking for something? Reported one Captain: There are several reasons why the Recall that holding lines lie perpendicular These fluids provide better protection against refreezing than Type I fluids. Air carriers, canadian airport, passenger screening, security measures. xref This could affect the handling qualities of your aircraft. for taxi clearance should not be initiated until the Captain and First Officer Flying (and taxiing) should never be hurried. Hazard identification is the process used to identify hazards.. ICAO Requirements. Pilots tend to taxi faster on runways than taxiways, exacerbating this problem. No doubt these problems could be minimized if crews would place the airport diagram chart where it could be easily referred to during Complete the medical terms based on their meanings and the word parts given. 0000012043 00000 n 0000247519 00000 n taxi in taxi out aircraft - aircraft taxiing hazards and remedy Joe would like to build several bookcases that are different heights and widths. of the two hundred twenty-four runway transgressions reported in 1991, forty-one Here are the top 5 mistakes I see routinely at our home airport. endstream endobj startxref What markings are used for reciprocating engine-powered airplanes? 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.
