NORMAL
PROCEDURES
GENERAL
This section describes the
procedures to be adopted for normal operations of the SB7L 360A aircraft.
The procedures are arranged in
the sequence considered to be the most desirable and therefore
steps should be performed in the order
listed unless good reasons for a deviation exist. The lists
below include checks for all optional
equipment, so checks that do not apply to this aircraft may
be skipped.

“Pulling
Through” The Engine
Before the first flight of the
day the engine must be “pulled through” by hand. This is the process
of turning the engine over by
turning the propeller by hand. The compression of each cylinder in
turn will be felt a resistance as the
propeller is turned. The engine should be rotated for a count
of at least 8 compressions.
Master
Switch............................................OFF
Ignitions.....................................................OFF
Throttle......................................................Closed
Propeller....................................................TURN
by hand & observe engine for odd
noises or heavy movements. Check for regular
compression.
CAUTION:
Prior to pulling through the
propeller by hand, the engine must be cold, both ignition circuits & the
Master Switch must be switched
OFF, the brakes applied & throttle closed.
WARNING
A
hot engine may fire with the ignition/s switched OFF.
DO
NOT pull through a hot engine.
CAUTION
Several causes of irregular
compression – such as poorly sealing valves – can lead to extensive
engine damage if not addressed. The
Seeker SB7L 360A Engine Instruction & Maintenance Manual
provides additional details.

Short
Field Landing
Approach.................................................
FLAT. Aim for wheels to touch as near to the
target point as possible. Approach under power.
Power
...................................................... APPROX 1500 RPM
Airspeed..................................................
55 KIAS
Touch-down.............................................
AT TARGET POINT. Wheel brakes are
the best way to slow the aircraft.
Touching down positively and slightly fast then braking
heavily (with caution) will give
shortest landing distances.
Power ...................................................... IDLE
Brakes......................................................
HEAVY. DO NOT LOCK WHEELS.
NOTE
Short
field landings are potentially high risk manoeuvres. Reducing approach speeds
and
approaching
under power reduce the aircraft’s safety margins, especially in a wind gust or
if the
engine
fails. Where possible, they should only be attempted in good conditions. If
students are
being
taught short field landings the weather conditions must be appropriate and a displaced
threshold
used.
NOTE
After
heavy braking such as that required for a short field landing brake
temperatures will rise
dramatically
and afterwards brake effectiveness may be significantly reduced.
