The left wing slats retracted due to the loss of hydraulic pressure and aerodynamic forces, while the right wing slats remained extended. The damaged electrical system prevented the slat retract indicators and stick-shaker on the yoke from functioning, so the crew was not alerted to the slat retraction nor impending stall.
When the pilot moves the aileron control to the left, or turns the wheel counter-clockwise, the left aileron goes up and the right aileron goes down. A raised aileron reduces lift on that wing and a lowered one increases lift, so moving the aileron control in this way causes the left wing to drop and the right wing to rise.
The on-ground angle of attack of the wing has to be established during the design phase. The main and nose-gear leg lengths are chosen to give a negative angle of attack relative to the ground. This ensures the wing will have negative lift until the pilot rotates the aircraft to a positive angle of attack. During landing, the reverse happens ...
a trim tab on the rear of the elevators or rudder which act to change the aerodynamic load on the surface. Usually controlled by a cockpit wheel or crank. [5] [7] an adjustable stabiliser into which the stabiliser may be hinged at its spar and adjustably jacked a few degrees in incidence either up or down. Usually controlled by a cockpit crank.
NEMA 1-15P (two-pole, no ground) and NEMA 5-15P (two-pole with ground pin) plugs are used on common domestic electrical equipment, and NEMA 5-15R is the standard 15-ampere electric receptacle (outlet) found in the United States, and under relevant national standards, in Canada (CSA C22.2 No. 42 [1]), Mexico (NMX-J-163-ANCE) and Japan (JIS C 8303).
Airbus A380 nose landing gear (consisting of a single 2-wheel bogie) 4 wheels, 2 axles: An Airbus A330's main landing gear (consisting of two 4-wheel bogies) 6 wheels, 3 axles: A Boeing 777's main landing gear (consisting of two 6-wheel bogies) 14 wheels, 7 axles: The Antonov An-225's main landing gear (consisting of two 14-wheel bogies)
The landing gear represents 2.5 to 5% of the maximum takeoff weight (MTOW) and 1.5 to 1.75% of the aircraft cost, but 20% of the airframe direct maintenance cost. A suitably-designed wheel can support 30 t (66,000 lb), tolerate a ground speed of 300 km/h and roll a distance of 500,000 km (310,000 mi) ; it has a 20,000 hours time between overhaul and a 60,000 hours or 20 year life time.
The procedure of de/anti-icing, protection from fluids freezing up on aircraft, is done from special vehicles. These vehicles have booms, like a cherry picker, to allow easy access to the entire aircraft. A hose sprays a special mixture that melts current ice on the aircraft and also prevents some ice from building up while waiting on the ground.
