Upset aircraft criteria include which of the following?

• A. +25 pitch, -10 pitch, 45 roll, or in appropriate airspeed
• B. +30 pitch, -15 pitch, 60 roll, or in high airspeed
• C. +20 pitch, -5 pitch, 30 roll, or in appropriate airspeed
• D. +10 pitch, -20 pitch, 50 roll, or in appropriate airspeed

Answer: (A)

Upset criteria define when a flight attitude is outside the normal envelope and requires prompt recovery. In standard upset training, the thresholds are a pitch of +25 degrees nose-up, a pitch of -10 degrees nose-down, and a bank of 45 degrees, with an additional condition that an out-of-range airspeed also signals an upset. The option that states +25 pitch, -10 pitch, 45 roll, or in appropriate airspeed matches these widely used thresholds, so it is the best choice. The other options use different numbers for pitch, bank, or omit the airspeed condition, which do not align with the usual upset criteria.
