‘Sailplane’ means a heavier-than-air aircraft that is supported in flight by the dynamic reaction of the air against its fixed lifting surfaces, the free flight of which does not depend on an engine. ‘Series Propeller’ means a propeller essentially identical in design, materials, and methods of construction, with one which has been previously approved. ‘Standard Atmosphere’ See ‘Atmosphere, International Standard’. *‘Stopway’ means an area beyond the take-off runway, no less wide than the runway and centred upon the extended centreline of the runway, able to support the aeroplane during an abortive take-off, without causing structural damage to the aeroplane, and designated by the airport authorities for use in decelerating the aeroplane during an abortive take-off. ‘Supplemental oxygen’ means the additional oxygen required to protect each occupant against the adverse effects of excessive cabin altitude and to maintain acceptable physiological conditions. *‘Take-off safety speed’ means a referenced airspeed obtained after lift-off at which the required one-engine-inoperative climb performance can be achieved. Terms associated with probabilities (for engines):– NOTE: Because an Effect can only be assessed in relation to a complete aircraft and as, for airworthiness purposes, each category of Effect is related to a particular frequency of occurrence, the definitions and associated numerical values are given in aircraft terms (hours in flight). Frequency of occurrences:– a ‘Reasonably Probable’ means unlikely to occur often during the operation of each aircraft of the type but which may occur several times during the total operational life of each aircraft of the types in which the engine may be installed. NOTE: Where numerical values are used this may normally be interpreted as a probability in the range 10–3 to 10–5 per hour of flight. |
