Operational Limitations

Question 1

Service Ceiling

Answer 1

The altitude at which an aircraft can sustain a 50ft per minute climb an important parameter defining the upper level of an aircrafts operational altitude (over engine) -14,000 Pressure Altitude (Cessna 172)

Question 2

Absolute Cieling

Answer 2

The maximum altitude an aircraft can climb under a normally-rated load

Question 3

Controllability

Answer 3

The aircrafts ability to respond to control inputs

Question 4

Maneuverability

Answer 4

The ability for the aircraft to change its flight path and withstand the forces associated with that movement

Question 5

Stability

Answer 5

The tendency for the plane to return to equilibrium after a control input

Question 6

2 Types of Stability

Answer 6

Dynamic: Effect Over Time
+ : Responds to the Control Input and lessens units returning to Normal
Neutral: Responds to the Control Input and remains
- : Responds to the Control Input and gets WORSE

Static : Intital Effect
+: Immediately Responds to Control Input and Returns to equilibrium
Neutral: Immediately Responds to Control Input and Stays
- : Immediately Responds to Control Input and GETS WORSE

Question 7

Stability Around the Vertex’s

Axis = Plane Movement = Stability Type = Aircraft Support Structure

Answer 7

Vertical Axis = Yawing Action = Directional Stability = Vertical Stabilizer/ Keel Effect

Longitudinal Axis = Rolling Action = Lateral Stability = Dihedral Wings

Lateral Axis = Pitching Action = Longitudinal Stability = Horizontal Stability
