Range and Endurance Mass Brief Aim • To Learn the principles of range and endurance of an aircraft in flight, and the factors that effect these conditions Application • In long distance flying the maximum Range is important • When holding the maximum Endurance or time in the air is important Overview • Revision – Thrust and Power • Definitions • Principles – Range and Endurance • Considerations • Airmanship Revision • Thrust • Power IAS Thrust Power IAS Definitions • Range – Air distance travelled for a given fuel burn-off (distance) • Endurance – Time in flight for a given amount of fuel (time) • Maximum Range Speed – A certain speed that will allow the aircraft to fly the furthest distance. • Maximum Endurance Speed – A certain speed that will allow the aircraft to stay in the air for the longest time • Best Range Speed – A practical speed that will allow the aircraft to fly the furthest distance. • Best Endurance Speed – A practical speed that will allow the aircraft to stay in the air for the longest time Principles • Maximum Range – Range is a certain distance, usually measured in nautical miles – Range is dependent on drag – Maximum range occurs when total drag is at a minimum Principles • Maximum Endurance – Is a certain amount of time an aircraft can spend in the air. – Endurance is dependant on the power setting of the aircraft – Power setting determines the burn-off (usually in Litres per hour) – Minimum power means minimal fuel flow – Maximum Endurance occurs at minimum power Principles • Best Range – Is a power setting taken from the POH (5-19) • Best Endurance – Is a power setting taken from the POH (5-20) Considerations • Effect of Airspeed Considerations • Effect of Weight Considerations • Effect of Wind • Power Considerations • Effect of Altitude (5-19 and 5-20) Airmanship • Always set the power according to cruise tables in POH • Always lean the mixture in accordance to the company policy • Never exceed any of the aircraft’s maximum limitations (MTOW or VNE) Summary of Range and Endurance • “For best range you should fly high and fast” • “For best endurance you should fly low and slow”
