(b)
Trim-locking lever is at control stick
(c)
Pull locking lever to free trim knob at left cockpit side
(d)
With the trim knob:
(1)
Elevator stick force can be trimmed to zero
(2)
Desired speed can be trimmed
(3)
Release locking lever after trimming to fix trim setting
(4)
Indication of trim setting shown by position of trim knob relative to neutral

deficiency.
(see below)
4.5.8 Baggage Compartment
Baggage compartment should be used for soft and light materials which would not obstruct the
pilot after deceleration or injure the pilot in crash landings. Maximum baggage 5 kg (11 lbs).
Baggage compartment load counts for useful load and must therefore be included, when
checking loading conditions.
For permanent installation of batteries, barographs, ELT etc. see Maintenance Manual chapter 11.
4.5.9 Balancing of Pilot Weight
Balancing of pilots with insufficient weight
3 trim weights can be fitted to a threaded rod in front of rudder pedals and secured by knurled nut.
1 trim-weight of 2.45 kg <5.5 lbs> compensates 5 kg <11 lbs> of pilot weight
When
removing
the
tail fin battery
(Standard weight 2.5 to 2.7 kg <5.5 to 6 lbs>), Minimum
Cockpit Load decreases by
10
kg <22 lbs>, see page 6-1/2.
Balancing of heavy pilots, who want to fly with rearward C.G. positions
(a)
For 10 kg <22 lbs> of pilot weight above
Minimum Cockpit Load with empty tail fin
tank
1.5 litres <0.4 US gallons, 0.33 Imp. gallons> of water may be filled into the tail fin
tank.
(b)
When using wing water ballast, this balancing method may be restricted due to amount of
wing water used and tail fin tank version, see also pages 4-9.
(c)
When discharging water ballast, this trim condition can not be kept due to quicker discharge
of tail fin water ballast.
(d)
When installing a battery
(
3BR-199
, Standard weight 2.5 to 2.7 kg, <5.5 to 6 lbs>)
in the
tail fin, Minimum
Cockpit Load increases by 10 kg <22 lbs>,
see also entries
on page 6-1/2.
Warning: Item d) Re-installation is permissible only
- when the C.G. weighing included the tail battery in this position
- when it had been removed for trimming afterwards.
