Angle Of Climb Flashcards
Climb Angle
Still air/relative to the air mass
Flight Path Angle
Effect of wind/groundspeed related
Vx
Best Angle Of Climb
Most excess thrust Vmd
Gradient formula
Vertical/Horizontal
VMP
L/D ratio lower than VMD
AOA more than 4 degrees
CL higher than VMD
Increase In Mass on angle of climb
Total drag curve moves up and right therefore Vx increases for heavier aeroplane
- shallower climb angle
- lower excess thrust
Aeroplane configuration on angle of climb
Dirty config moves total drag curve up and left (flaps/landing gear/spoilers)
- increased parasite drag reduce angle of climb
- reduce excess thrust
- reduces VX speed
Altitude (Jet AC) on angle of climb
Angle of climb reduces
Vx (IAS remained constant)
Vx (TAS increases)
Altitude (Prop AC) on angle of climb
IAS and TAS increase with altitude with reduced excess thrust
VMP faster with altitude
Engine Failure (Jet) - Angle Of Climb
Increase parasite drag - up and left
Smaller range of speeds to climb at
Vx slightly lower
(One engine out Vx speed) - green dot
Engine failure - Propeller
Drag curve moves up and left
Large reduction in thrust
VXSE is higher than all engine Vx
Second Segment
One engine out
Take off climb
Climb starting above the runway surface to the initial cruising altitude
Approach climb definition
Climb made after you have initiated a go around during the approach when in approach config (flaps in approach config/landing gear UP) one engine failed
Landing climb definition
Climb made after go initiating go around in landing config (flaps in landing position and landing gear down)
