User manual

1.) When flying with internal fuel only (Forward and Rear Tank) both the Forward Tank
Fuel Pump and the Rear Tank Fuel Pump are to be switched on. The Rear Tank
Fuel Pump is to be switched off as soon as the Rear Tank is empty to avoid that the
pump is running dry. Switch Fuel Content Display to Forward Tank.
2.) When Flying with Drop Tank all three the Forward-, Rear-, and Drop Tank Fuel
Pump are to be switched on initially. When the Drop Tank is empty, turn off the
corresponding Fuel Pump and release the empty Tank (red Lever, lower forward
panel). Continue as described in 1.). There is no indicator for Drop Tank Content.
The Drop Tank is empty as soon as the Rear Tank Fuel Content begins to drop.
3.) (A-8 and A-9) Flying with Aux Tank, proceed in the sense as described under 2.)
4.) (A-8 and A-9) Flying with a full fuel load (Forward, Rear, Drop Tank and Aux Tank)
The Aux Tank should be used first so that a somewhat unappreciative CoG shift
due to the extra fuel can be compensated. Forward-, Rear- and Aux Fuel Pumps
on initially until Aux Tank is empty (fuel warning lower forward panel, right hand).
Turn Off Aux Tank Fuel Pump, turn on Drop Tank Fuel Pump. Proceed as
described under 2.) .
Gear Operation
The gear is driven by an electrical motor.
As the gear retracts, a pressurized air bottle is loaded which lowers the gear in the event
of an electrical failure.
The electrical gear switches are located in the left console fairly at the centre in a
combined instrument along with the flap switches (Figure 1).
The gear unlock mechanism (Figure 2) is located left hand in the lower forward panel,
labelled “Notzug Fahrwerk”.
Retract gear: remove safety cover from switch 2 (Figure 1) and press it.
Extend gear: press switch 1 (Figure 1) to activate the gear motor,
next pull the lever (Figure 2) to unlock the gear.
WARNING!
Always activate the gear motor before pulling the lever except in an
emergency. The gear can no longer be retracted otherwise.
