3.8 COM and NAV Equipment
COM and NAV equipment is installed in the centre part of the instrument panel.
The loudspeaker is installed on the rear wall of the cockpit above the LH baggage compartment. The
gooseneck-microphone is fastened between the backrests at the centre console. When using the headsets it
can be deselected to reduce background noise.
Antennas are installed for:
UHF-COM in rudder,
VOR-NAV on cockpit floor (Kevlar shell, optional equipment, later installation is not possible)
Transponder antenna in the front part of the tail cone or at propeller-dome.
Only equipment, listed in section 9 of this Maintenance Manual and certified in association to the S10-VT,
may be installed without additional certification. Only for this equipment has proper function according to
certification requirements been proven by the manufacturer. For modifications, the installation instruction and
the original wire-harness of the a/c manufacturer must be used. This is also relevant for equipment approved
for operation in powered sailplanes or equipment without certification requirements due to possible influence
on power consumption, electromagnetic influence and structural characteristics of the instrument panel.
Outside Germany it must be confirmed that the equipment is certified by the local authority which certified the
a/c.
The weight limits for the equipment installed in the instrument panel (without structural reinforcement: engine
instrumentation plus 10 kg / 22 lbs) and the influence on CG must be observed. The Equipment List and the
Weight and Balance Report must be updated.
When equipment is modified, conformity with the type must be checked and confirmed by an inspector. If
equipment is installed that is not certified with the a/c, it must be proved to the authority, that the applicable
requirements are fulfilled (modification of a single a/c).
3.9 Oxygen System
One or maximum two oxygen system mountings (optional equipment) for one oxygen bottle each are
installed in the upper baggage compartment. The mountings are suitable for oxygen bottles from various
manufacturers, provided the diameter is within a minimum of 132 mm / 5.2 in., and the total length including
regulator is approx. 450 mm / 17.7 in. through a maximum of 520 mm / 20.5 in..
The certification of the powered glider does not include a certain oxygen system and fulfilment of the
requirements must be demonstrated to the authority by the supplier or the facility, which modified the a/c
(normally as a modification of a single a/c).
