A change in the fleet configuration would lead to a change in the wake turbulence categories of the aircraft that would directly impact operating parameters such as runway movement and delays. Below is a list of IATA Aircraft Type Codes with ICAO tie-ups used in Airline Computer Reservation Systems, Timetables, Airport Information Systems and Schedule Data Publications. New items on the ICAO flight plan include a Wake Turbulence category, and Type of Flight. Same Runway Separation (SRS) 5 2-12. How to fly the aircraft? All aircraft generate vortices at the wing tips as a consequence of producing lift. The heavier the aircraft and the slower it is flying, the stronger the vortex. Page Content. Hitting wake is not fun and can lead to catastrophic consequences. The greatest danger is the roll induced on the penetrating aircraft to the degree that it exceeds the counter control capability of the aircraft concerned. For instance, the wake of larger aircraft can impose rolling moments that exceed the roll control authority of smaller encountering aircraft. You will even get to say it after your callsign on initial contact with ATC. Doc 8643 or based on weight and the following options: “L” for Light (< 7,000 kg), “M” for Medium (7,000 to 136,000 kg), “H” for Heavy (> 136,000 kg), and “J” for Jumbo (exceptionally heavy aircraft such as the Airbus A380-800). All aircraft generate vortices at the wing tips as a consequence of producing lift. However stand by for a change! D contains most large longhaul planes. (Refer to 14 CFR Part 97.) This list is from the Part Time Pilot Online Ground School and is the exact list of knowledge areas listed in the FAA Private Pilot Airmen Certificate Standards (ACS). The heavier the plane, the heavier its wakes, so it’s IAS 170 kt. 2. For the purposes of wake turbulence separation minima, aircraft are categorized as Category A through Category F. Each aircraft is assigned a category based on wingspan and maximum takeoff weight (MTOW). Inheritance.

They used to just be based off MTOWs: Super (the A380 held this spot) Heavy (anything with a MTOW more than or equal to 136 tons) Medium (7 tons to 136 tons) The jetwash is turbulence form by the aircraft engine. The combination of radial velocity distribution and FFT spectrum characterization are used to identify the core position of wake vortex. [C] The pilot-in-command of the aircraft. The importance of the drag devices (size of the landing gear, of the flaps, etc.). Among other factors, the size of the vortex is proportional to the span of the aircraft which generates it. List some Heavy Wake Turbulence category aircraft: B747 A340 B767 AN24 B52 - Boeing Stratofortress IAS 300 kt. At present, the only such type is the 12 14. After their first practice test they fill out this checklist. Wake turbulence is a disturbance in the atmosphere that forms behind an aircraft as it passes through the air.

[D] The state which issued the licence held by the pilot of the aircraft. According to a SAFO issued last October, the FAA will be transitioning to a new 6 category wake turbulence classification system in the near future. At low altitudes, vortices generally persist for as long as 80 seconds, but in very light or calm wind conditions, they can last for up to two and a half minutes. It is not only the duty of an ATC controller to guide the airliner about the wake turbulence but it is also a duty of the pilot to ensure that the aircraft is flying at a safe distance. AIRCRAFT CLASSES- For the purposes of Wake Turbulence Separation Minima, ATC classifies aircraft as Heavy, Large, and Small as follows: a. The FAA 7110.65U (most current FAA air traffic controllers handbook) classifies the H25B in the (L) wake turbulence category. This paper evaluates the wake vortex characteristics using pulsed coherent Doppler lidar (PCDL) under near-ground effect (NGE). Because of the possible effects of wake turbulence, controllers are required to apply no less than minimum required separation to all aircraft operating behind a Super or Heavy, and to Small aircraft operating behind a B757, when aircraft are IFR; VFR and receiving Class B, Class C, or TRSA airspace services; or VFR and being radar sequenced.

It includes various components, the most important of which are wingtip vortices and jetwash. 2-10. The turbulence persists several minutes and may remain present after the aircraft is out of sight. : 25 The purpose of the flight was to flight check three Delta pilots. Wake turbulence category of aircraft as speci˜ed in ICAO Did you know? Jetwash refers to the rapidly moving gases expelled from … Therefore, wake turbulence is more intense behind large, transport category aircraft than behind small aircraft. Doc 8643 or based on weight and the following options: “L” for Light (< 7,000 kg), “M” for Medium (7,000 to 136,000 kg), “H” for Heavy (> 136,000 kg), and “J” for Jumbo (exceptionally heavy aircraft such as the Airbus A380-800). What really needs to happen is educating ARTCC personnel to understand the lethal danger of heavy and super aircraft wake turbulence at altitude and their adverse and potential deadly effect on smaller category aircraft. The wake-turbulence category also is used to guide the separation of aircraft. • Wake Turbulence • Weather as a Contributing Factor in Aircraft Mishaps.

Wing vortices however, is extremely turbulent form at the wing tip of wing section due to pressure differential and can last in the air up to three minutes. J (Super) aircraft types specified as such in Doc 8643 (Aircraft type designators). Wake turbulence is a disturbance in the atmosphere that forms behind an aircraft as it passes through the air.
