Since landing is the most dangerous stage of a flight, it is important to be pre-warned if an engine failure may be likely to occur or to deal with any problem at this point. The checklist of actions is given below in its most complete possible form. O-B-U-M-M-M-P-F-F-I-T-C-H-H O - Open carburettor heater; B - Brakes free; U - Undercarriage ...
A lack of standardization and training in both aircraft maintenance and flight operations was cited as a causal factor in a large percentage of mishaps. Several standardization programs were initiated in the late 1950s and early 1960s to counter this problem. The first was the Naval Aviation Maintenance Program (NAMP) in 1959.
The three critical flight dynamics parameters are the angles of rotation in three dimensions about the vehicle's center of gravity (cg), known as pitch, roll and yaw. These are collectively known as aircraft attitude , often principally relative to the atmospheric frame in normal flight, but also relative to terrain during takeoff or landing ...
The position of all three axes, with the right-hand rule for describing the angle of its rotations. An aircraft in flight is free to rotate in three dimensions: yaw, nose left or right about an axis running up and down; pitch, nose up or down about an axis running from wing to wing; and roll, rotation about an axis running from nose to tail.
The "power-pitch couple" in light aircraft is usually small, that is, the engine is positioned in line with the centre of gravity, so changes in power do not cause large changes in pitch. UPRT techniques are designed for jet aircraft, particularly with underslung engines where a large increase in thrust can cause the aircraft to pitch up (the ...
A pilot of a DC-10 consulting his checklist. In aviation, a preflight checklist is a list of tasks that should be performed by pilots and aircrew prior to takeoff. Its purpose is to improve flight safety by ensuring that no important tasks are forgotten. Failure to correctly conduct a preflight check using a checklist is a major contributing ...

CIGAR or CIGARS is a mnemonic that refers to a pre-takeoff checklist performed by general aviation pilots. The mnemonic stands for: [1] Controls; Instruments; Gas; Airplane secure; Run-up. Alternately: [2] Controls; Instruments; Gas; Attitude; Run-up; Yet another version was used by the U.S. Air Force: [3] CIGarettes For The Poor Russian ...
