b. ‘Remote’ means unlikely to occur to each aircraft during its total operational life but may occur several times when considering the total operational life of a number of aircraft of the type in which the engine is installed. NOTE: Where numerical values are used this may normally be interpreted as a probability in the range 10–5 to 10–7 per hour of flight. c. ‘Extremely Remote’ means unlikely to occur when considering the total operational life of a number of aircraft of the type in which the engine is installed, but nevertheless, has to be regarded a being possible. NOTE: Where numerical values are used this may normally be interpreted as a probability in the range 10–7 to 10–9 per hour of flight. ‘Total Equivalent Static Power’ (turbine engines) means:– Total equivalent static power kW (S.I. Units) = Static jet thrust (N) Propeller shaft power + 15 Total equivalent static power (horse-power) (Non-S.I. Units) = Static jet thrust (lbf) Propeller shaft HP + 2.6 *‘True airspeed’ means the airspeed of an aircraft relative to undisturbed air. True airspeed is equal 1.2 to equivalent airspeed multiplied by (ρο/ρ ). Turbine Engines:– Power/thrust definitions applicable to engines for aeroplanes and helicopters:– NOTES: (1) The performance data are provided be the engine constructor and give the power and/or thrust produced by an engine under specified conditions (e.g. intake efficiency, forward speed, atmospheric temperature) when operating within the limitations (e.g. rpm, exhaust gas temperature) which have been approved for use with the defined power/thrust condition. |
