LIMITATIONS
2.8 MANEUVER LIMITS
This airplane is designed for non-aerobatic operations.
These include any maneuvers incidental to normal flying, stalls (except whip stalls), lazy
eights, chandelles, and turns in which the angle of bank is not more than 60°.
WARNING
Aerobatic maneuvers, including spins, are not approved.
Non – aerobatic maneuvers are approved and they are listed below:
MANEUVER
RECOMMENDED ENTRY SPEED*
Chandelles
167 km/h – 90 (knots)
Lazy Eights
157 km/h – 85 (knots)
Steep Turns
148 km/h – 80 (knots)
WARNING
Abrupt use of the controls is prohibited above 165 km/h - 89 (knots)
CAUTION
Aerobatics that may impose high loads should not be attempted.
The important thing to bear in mind in flight maneuvers is that the airplane is clean in
aerodynamic design and will increase up speed quickly with the nose down. Proper speed
control is an essential requirement for execution of any maneuver, and care should always
be exercised to avoid excessive speed which in turn can impose excessive loads. In the
execution of all maneuvers, avoid abrupt use of the controls. Intentional spins with flaps
extended are prohibited.
