tank
Hose from expansion tank to overflow bottle:
See Fig. 5.
- The hose from the expansion tank to the overflow bottle must be rated
for vacuum/suction for min. 125 °C (257 °F), e.g. it must be strong
enough to withstand high temperatures and vacuum/suction during the
cooling down period.
The aircraft manufacturer must give the possibility to the pilots to check
the coolant level in the expansion tank. Also it is necessary to inform the
pilots about the daily inspection of the coolant level in the aircraft manufac-
turers operators (pilots) manual or an adequate link to the ROTAX 912 i
Series Operators Manual.
It is recommended that adequate measures are taken for carrying out
these inspections, e.g. a flap or panel on the cowling or a warning instru-
ment in the cockpit for low coolant level.
