Why does the FAA recommend no faster than VA or VO for steep turns?

In level-turn loading, the airplane stalls before exceeding its design load limit.

  1. In level-turn loading, it stalls before exceeding design load ✔
  2. It uses the least fuel at that speed
  3. It makes the overbanking tendency disappear

Why: Steep turns raise load factor. In the level-turn loading described by the FAA, an airplane at or below VA or VO stalls before exceeding its design load limit.

Huh, didn't know that: The AFH says a level turn at 75 degrees of bank exceeds the 3.8 G limit of a normal category airplane.

The dad joke
Maneuvering speed is the airplane's way of saying: I'll faint before I break.
