MANEUVER LIMITS
NORMAL CATEGORY
This airplane is certified in the normal category. The normal category is applicable to airplanes intended for non‐
aerobatic operations. These operations include any maneuver incidental to normal flying, such as stalls (except
whip stalls), lazy eights, chandelles, and steep turns in which the angle of bank is not more than 60 degrees.
AUTHORIZED MANEUVERS
1.
Any maneuver incidental to normal flying
2.
Stalls (except whip stalls)
3.
Lazy eights, chandelles, and steep turns, in which the angle of bank is not more than 60 degrees.
UNAUTHORIZED MANEUVERS
Any acrobatic operation including spins.
Design Maneuvering Speeds (V
A
)
Minimum Weight (2800 pounds):
105 KCAS (105 KIAS)
Maximum Weight (3800 pounds):
121 KCAS (120 KIAS)
The important thing to remember in flight maneuvers is that the airplane is clean in aerodynamic design and will
build up speed quickly with the nose down. Since proper speed control is essential for execution of a maneuver,
care should always be exercised to avoid excessive speed and its resultant heavy airframe loads. In the execution
of all maneuvers, avoid abrupt use of controls.
