For Transport Category aircraft of over 12,5001b Max TOW (in the USA—over 5,700kg elsewhere), take-off and landing distances correspond to fully-factored require ments for much of the world. For the lighter types the performance data is unfactored gross performance which may or may not need adjust ment for Public Transport operations. Speeds V2 is the take-off safety speed at maximum TOW; VAT the target threshold speed at maximum landing weight; VMO, (VNO in the United States) is the maximum and the normal operating speed; while VNE is the "never exceed" speed. Speeds generally are given in knots and km per hour, indicated, although some values may be in either calibrated or equivalent airspeed. Cruise performance shows the speed, the alti tude and, where available, the fuel consumption for up to three sets of cruise conditions corre sponding in turn to a maximum speed cruise, a co9t-economical one, and a long-range condition. Those aircraft without pressurisation have been limited to a maximum cruise altitude of 10,000ft (3,048m). Payload range is under ISA still-air en-route conditions with NO reserve fuel provisions. Obviously this is not a practicable operating procedure, and the figures are only shown in this way to try and ensure true comparability. In service these maximum ranges would be reduced considerably, the precise extent of the reduction depending on the reserve fuel policy adopted by the airline or required by the regulatory authority. The figures quoted also relate to the assumed operating weight and to the standard fuel capacity. A ' FLIGHT International, 11 May 1985 55
