DART improves PA100’s RFMS

July 25, 2018  By Helicopters Staff

DART Aerospace has made an improvement to the Rotorcraft Flight Manual Supplement (RFMS) for its PA100 PUREair engine protection system for Airbus Helicopters H125/AS350 and H130/EC130.

In order to unlock some additional power, DART explains it began working with PALL Aerospace Corp. to support a new flight test program, where additional data was gathered. This allowed the two organizations to reduce RFMS restrictions on a PA100 equipped aircraft.

The previous RFMS applied an 85 kg penalty when calculating hover performance, explains DART, regardless of whether the aircraft could pass the OEM Engine Health Check with the PA100 installed.

Following this new battery of tests, DART explains this penalty was removed completely in cases where an aircraft could pass the OEM Health Check with the PA100 installed. As a result, for operators of the AS350B3e with Arriel 2D engines, the VEMD can be configured so that there is no performance penalty with the PA100 installed.

For operators of AS350B3 (and earlier) aircraft and EC130B4/T2 aircraft that do not pass the OEM Health Check with the PA100 installed, DART explains penalties have been reduced to 52 kg (HIGE) and 58 kg (HOGE).


DART says this improved performance is available to all new deliveries as well as existing customers already operating this system.
