AIR PERFORMANCE 35 



PART I. : GLIDING FLIGHT. General Landing speed on glide, 

 first method Second method Gliding angle Gliding in a wind. 

 PART II.: FULL POWER FLIGHT. General Top speed Top 

 speed at an altitude Racing machines Rate of climb, first ap- 

 proximation Second approximation Third approximation 

 Comparison of the three approximations Times to altitudes, 

 general method Case when climb is a linear function of altitude 

 Ceiling. PART III. : THROTTLED FLIGHT. Slowest flying 

 speed Throttling curves Consumption and revolutions when 

 throttled Best cruising speed at given altitude Best cruising 

 altitude Long range cruising.

General Getting off a deck Getting off the ground Landing 

 on a deck Landing on the ground Propeller thrust at slow 

 speeds Total resistance Minimum flying speed when getting off.
