Climbing & Descending Flashcards
(48 cards)
What are the four forces acting on an aircraft?
Lift, weight, thrust and drag
What is equilibrium?
When all the forces are in balance and there is no acceleration.
I.e. L=W and T=D
What are the forces in a steady climb?
T>D and L
What balances out the horizontal weight component in a climb?
Excess thrust
What are the three types of climb?
BAoC
BRoC
Cruise Climb
Why use BAoC?
Max vertical distance for min horizontal distance
Used for obstacle clearance
How is BAoC achieved?
Speed for max excess thrust
Why use BRoC?
Max vertical distance for the min amount of time
How is BRoC achieved?
Speed for max excess power
Why is a cruise climb used?
Better forward visibility and better engine cooling
What happens if you fly faster or slower than BAoC speed?
Decreases excess thrust, reducing the angle of climb
What happens if you fly faster or slower than BRoC speed?
Decrease excess power available, decreasing rate of climb
Does wind impact rate of climb?
No
What impact does a headwind have on angle of climb?
Increases angle of climb
What impact does a tailwind have on angle of climb?
Decreases angle of climb
What impact does an increase in weight have on angle of climb?
Reduces angle of climb
What impact does an increase in weight have on rate of climb?
Reduces rate of climb
What impact does a higher or lower airspeed than prescribed have on angle of climb?
Reduces angle of climb
What impact does a higher or lower airspeed than prescribed have on rate of climb?
Reduces rate of climb
What impact does reducing power have on angle of climb?
Reduces angle of climb
What impact does reducing power have on rate of climb?
Reduces rate of climb
What do flaps do?
Increase lift and drag, typically more drag than lift
How do flaps impact angle of climb?
Reduces angle of climb
How do flaps impact rate of climb?
Reduces rate of climb
