As the instruments need a separate power supply and a different design for the
electrical oil pressure sensor, the resistance type instrument (type VDO), which
was supplied by BRP-Powertrain up to now, is not suitable anymore. Suitable
instruments are offered by various instrument manufacturers (e.g. ROAD or
Aviasport).
▲ WARNING: Certification to the latest requirements such as FAR of EASA
has to be conducted by the aircraft manufacturer.
