AIRPLANE FLIGHT MANUAL - MODEL 8KCAB Revision: H
Issued:
For operational procedures related to cold weather operation consult the
Lycoming Operators Manual. Due to the length of oil lines, special care should
be exercised during starting to assure that engine oil pressure is obtained within
30 seconds after start.
It is recommended that the engine compartment be preheated prior to start if the
ambient temperature is below 20
°
F.
2.1.8 Acrobatic Operation
Maneuvering speed (V
A
) is maximum speed (for an established operating weight)
at which full and / or abrupt use of the elevator control will not cause load factors
in excess of the +6 G’s in Normal Operations or –5 G’s in Inverted or Outside
Operations.
Full and / or abrupt movement of ailerons may be used at speeds up to V
A
provided that the load factor does not 4 G’s or –3.2 G’s. Use of ailerons
above V
A
or above +4 G’s or –3.2 G’s should be smooth and limited to
deflections which will cause a roll rate not exceed that roll rate achieved with full
aileron at V
A
.
Caution: Full abrupt use of the ailerons with simultaneous use of full abrupt
elevator at VA may produce loads in excess of design limits.
Propeller RPM is limited to 2600 RPM maximum during acrobatic maneuvers.
For solo acrobatic operations, determine that the rear seat folding back has
restrainer cables to prevent back from folding completely forward and interfering
with rear stick movement. Ascertain that all loose or hanging objects, including
unused seatbelts, are removed from the aircraft or are secured to prevent
movement in flight.
