This Item extends to propeller-driven aeroplanes, powered by piston or turbine engines, the method of Item No. 74018 for estimating the 'lost' range, 'lost' fuel and 'lost' time due to climb and descent. The use of these quantities permits estimates of still-air range, fuel and time based on cruise performance alone to be adjusted for the effects of climb and descent. The method is based on the concept of energy height which is itself introduced in Item No. EG 3/3. It is best suited to preliminary calculations at a stage when the available airframe, engine and propeller data are minimal and for cases where the distances flown in climb and descent are not a substantial part of the total flight distance.
