42When operating at a constant airspeed with constant thrust setting at high altitude (typically above FL250) in slow flight below L/D max airspeed, any disturbance causing a decrease in airspeed will result in a further decrease in airspeed unless thrust is increased.

43Maximum Altitude is the highest altitude at which an airplane can be operated. In today’s modern airplanes it is determined by basic characteristics unique to each airplane model. Maximum Altitude for an airplane is:

- CBuffet or Maneuver Limited Altitude – the altitude at which a specific maneuver margin exists prior to buffet onset.
- DThe highest of the above listed altitudes.
- EThe lowest of the above listed altitudes
44At high altitude, an aft loaded airplane will:
- ABe more responsive to control pressures since it is less stable than a forward loading.
- BBe less responsive to control pressures as there is a longer moment arm from the center of gravity to the tail assembly.
