When we were starting up an IFR EMS Program using BK-117's in an area based on the shoreline of one of the Great Lakes.....I made myself very unpopular when I raised questions about the ramifications of various electrical and fuel pump failures.
Not only did such failures impact the flying of the aircraft, fuel endurance, but also the loss of vital Mission Equipment that would have an impact on Critical Care Patients in the back.
Much planning and foresight is required when outfitting and equipping an aircraft for new tasks.
If, as stated by more than one Poster, the Crews of Police aircraft found the Caution Lights to interfere with NVG use and thus that was a reason for moving switches.....might that have had a role in this accident.
