Maintenance Tool - Rotax 912 i Series Installation Manual

3) Ambient air, pressure, temperature sensor (AAPTS)
The AAPTS sensor is the all-in-one sensor for engine ambient tempera-
General
ture and engine ambient pressure. In cowled engine installations it has to
be mounted in the engine compartment in a ram air free area and close to
the air inlet. The sensor should measure the correct air inlet temperature
and the air pressure right before the air filter.

4) Maintenance tool

For engines of the ROTAX 912 i Series, the maintenance and diagnostic
General
software B.U.D.S. Aircraft is available. This provides not only the reading
of ECU logs, it also provides a variety of functionalities to support trou-
bleshooting of the engine. To start this software and connect the engine
with a computer a B.U.D.S. Aircraft kit is required. This is a USB adapter,
that provides different software functionalities depending on its version.
