Descending Flashcards
What is in equilibirum in a steady glide?
Weight, drag and lift
In a descent, how do drag and glide relate?
The greater the drag force, the steeper the glide
What forces increases the glide steepness?
Drag
A glide angle of descent is low when the L/D ratio is
High
A glide angle of descent is high when the L/D ratio is
Low
The most efficient aerodynamic flight in a descent is flown when what key factor is greatest?
Lift/Drag Ratio
What three factors affect glide angle?
Airspeed
Flap setting
Weight
If the glide airspeed is not flown, what happens to the aircraft’s glide?
It steepens (regardless of whether too fast or too slow)
What do flaps do to a L/D ratio?
Reduce the ratio
What do flaps do to a glide?
Steepen it
Why is L/D ratio lower with flaps extended?
Drag is increased more than the lift
As weight reduces, what happens to AoA and airspeed?
The airspeed will be lower for any gievn AoA
How does weight affect glide angle?
It doesn’t change the glide angle, but reduces the gliding speed
If an aircraft weighs less in a glide, how are glide factors affected?
Glide angle remains constant
Glide speed reduces
A headwind ____ glide distance?
Reduces
