rate of climb, angle of climb

Asked by: 4008 views Aerodynamics

rate of climb-> excess power

angle of climb-> excess thrust

i don't know why power and thrust must be distinguished..

i understand the definition but don't know how it applied to real performance.

especially thrust..

how do we recognize thrust available and thrust required in airborne?

    “how do we recognize thrust available and thrust required in airborne?”

    You don’t. When you want to maximize your climb rate or climb angle, you follow the procedures outlined in your Airplane Flight Manual that tell you how to achieve this performance. Excess power and excess thrust provide the basis for understanding why the AFM procedures are the way they are, but you don’t need to know about them to operate the airplane.

    1) rate of climb-> excess power – rate of climb has to do with gaining altitude over TIME.

    2) angle of climb-> excess thrust – angle of climb has to do with distance.

    “how do we recognize thrust available and thrust required in airborne?”

    You need to know the airspeed that will give you best angle of climb. The you have to know what pitch to set to obtain that airspeed when you do an obstacle clearance takeoff.

    Knowing how to measure available vs. required sounds like a question for engineers on the ground.
