Table II-5-1-2 Aircraft approach categories do not change during day-to-day operation. To change an aircraft's category, an aircraft must be re-certified with a different maximum landing mass. [1]: II-5-1-3 Pilots may not use a lower category than the one certified, but may choose to use a higher category for higher speed approaches. [2]
A single-engined Cessna 150L's airspeed indicator indicating its V-speeds in knots. In aviation, V-speeds are standard terms used to define airspeeds important or useful to the operation of all aircraft. [1] These speeds are derived from data obtained by aircraft designers and manufacturers during flight testing for aircraft type-certification.
An approach plate for the ILS or LOC approach to runway 14L at Cologne Bonn Airport, Germany. Approach plates (or, more formally, instrument approach procedure charts) are the printed or digital charts of instrument approach procedures that pilots use to fly instrument approaches during instrument flight rules (IFR) operations.
The higher the speed of the aircraft, the easier it is to counteract the yawing moment using the aircraft's controls. [8] The minimum control speed is the airspeed below which the force the rudder or ailerons can apply to the aircraft is not large enough to counteract the asymmetrical thrust at a maximum power setting.
An "approach plate" depicting an instrument approach procedure for an ILS approach to Tacoma Narrows Airport in the United StatesIn aviation, an instrument approach or instrument approach procedure (IAP) is a series of predetermined maneuvers for the orderly transfer of an aircraft operating under instrument flight rules from the beginning of the initial approach to a landing, or to a point ...
V A is the design maneuvering speed and is a calibrated airspeed.Maneuvering speed cannot be slower than and need not be greater than V c. [4]If is chosen by the manufacturer to be exactly the aircraft will stall in a nose-up pitching maneuver before the structure is subjected to its limiting aerodynamic load.
Turn at constant speed Approach and landing Takeoff. The speed, height and trim angle of attack are different for each flight condition, in addition, the aircraft will be configured differently, e.g. at low speed flaps may be deployed and the undercarriage may be down.
Aircraft performance refers to the ability of airplanes and helicopters to accomplish certain useful things. [1] It is an important consideration when designing and testing aircraft, to ensure the aircraft can be operated in an efficient and economic manner. [ 2 ]
