[17] [18] The previous three wake turbulence categories were increased to six, by splitting Medium and Heavy into pairs, and adding a Super Heavy category for the Airbus A380. [19] Capacity gains of up to 8% were achieved. [17] RECAT-EU was initially deployed at Paris Charles de Gaulle and Paris Le Bourget airports in 2016. [20] [21]
A typical light aircraft: the Cessna 172 With a maximum gross takeoff weight of 12,500 lbs, the DHC-6 Twin Otter is an example of the upper limit of the light aircraft category. A Robinson R44 light helicopter. A light aircraft is an aircraft that has a maximum gross takeoff weight of 12,500 lb (5,670 kg) or less. [1]
The aircraft gross weight (also known as the all-up weight and abbreviated AUW) is the total aircraft weight at any moment during the flight or ground operation. [ 1 ] [ 2 ] [ 3 ] An aircraft's gross weight will decrease during a flight due to fuel and oil consumption.
Assisted takeoff is any system for helping aircraft into the air (as opposed to strictly under its own power). The reason it might be needed is due to the aircraft's weight exceeding the normal maximum takeoff weight, insufficient power, or the available runway length may be insufficient, or a hot and high airfield, or a combination of all four ...
Helicopters also produce wake turbulence. Helicopter wakes may be significantly stronger than those of a fixed-wing aircraft of the same weight. The strongest wake will occur when the helicopter is operating at slower speeds (20 to 50 knots). Light helicopters with two-blade rotor systems produce a wake as strong as heavier helicopters with ...
The maximum takeoff weight (MTOW) or maximum gross takeoff weight (MGTOW) or maximum takeoff mass (MTOM) of an aircraft, also known as the maximum structural takeoff weight or maximum structural takeoff mass, [1] is the maximum weight at which the pilot is allowed to attempt to take off, due to structural or other limits.
By October 2018, the in-service and stored helicopter fleet of 38,570 with civil or government operators was led Robinson Helicopter with 24.7% followed by Airbus Helicopters with 24.4%, then Bell with 20.5 and Leonardo with 8.4%, Russian Helicopters with 7.7%, Sikorsky Aircraft with 7.2%, MD Helicopters with 3.4% and other with 2.2%.
Aircraft flight mechanics are relevant to fixed wing (gliders, aeroplanes) and rotary wing (helicopters) aircraft.An aeroplane (airplane in US usage), is defined in ICAO Document 9110 as, "a power-driven heavier than air aircraft, deriving its lift chiefly from aerodynamic reactions on surface which remain fixed under given conditions of flight".
