After fitting FLIR and NVG-equipment in our BK117-fleet, the stuff had that to be approved.
Some more pages in the book - and its written down, NVG-operatins only with a crew of two Pilots.
Was done at Alanmann (

Could this be a new optional equipment with new RFM supplement?
All BK users i know operating in such configuration (NVG, FLIR) have a standard crew of one pilot and one FLIR operator. A second pilot is of course not prohibited but not required.

FLIGHT MANUAL BK 117 B-2 EUROCOPTER
