35. Thrust, Stability, & Center of Gravity Flashcards
Unlike an automobile, your airplane can only be loaded to a certain weight. If it is loaded beyond the maximum allowable weight it will experience:
- Higher stall speeds and longer takeoff distance
- Lower rate of climb
- Longer landing roll.
If an airplane is loaded with the CG forward of the allowable range:
The pilot needs to use more back pressure on the elevator to hold the nose up.
Lateral or roll stability is normally achieved by:
The upward pitch of the wings, called dihedral.
An airplane is designed for stability. Stability can be described:
An airplane is stable if it will return to its original flight attitude after it has been disturbed.
In straight-and-level flight, if thrust exceeds drag then:
Speed increases.
For directional stability, an airplane tends to weathervane back to a stable position due to:
More fuselage aft of its CG.
If the loaded center of gravity is aft of the allowable range, pitch stability:
Is reduced.
In steady unaccelerated flight:
Lift equals weight.
The total weight of an airplane is comprised of:
- Airplane
- Crew and passengers
- Fuel
- Baggage.
