Best Endurance is achieved by flying at the A??
AOA which yields minimum fuel flow per hour.
Best Endurance occurs at a speed for Vimd and at an altitude where Vimd can be achieved using engine .. .. ..
design RPM
Wind has NO EFFECT on endurance because.. .. ..
fuel flow per hour is unaffected by wind!
As FOB is burnt, weight reduces, the drag curve moves down and left resulting in
LOWER maximum endurance speeds at LOWER Gross Weights!
The AOA for best endurance is
FIXED!
The speed for best endurance is dependant on w & a
Weight and Altitude!
(climbing)
Max AOC is achieved by flying at V?
Vimd
As weight reduces the curve moves down and left resulting in lower ….
Excess thrust speeds at lower gross weights!
AOA for max AOC is fixed but the speed depends on W & A
Weight and Altitude
Max ROC achieved using max
Power
Power available is developed by multiplying thrust by T….
TAS
Power available at Zero TAS is…
ZERO –> and increases as TAS increases.
Flaps increase lift and drag moving the curve up and….
LEFT
As flaps are lower Vimd
decreases!
Power available decrease with altitude. TAS or max ROC is higher with increased altitude but the IAS is….l
Lower!
