I can't for the life of me establish any emergency or requirement that would have me grabbing at the governer switch on the 212/412 in a nanosecond....all emergencies, actions, procedures that I can think of, has the frictions off, throttle back to flight idle, check, then double check that you have the correct switch, activating it, then advancing the throttle again.....so my view view its not a time issue!!
Our company did go through the exercise of placing a cover over a modified double actioned switch [Giving you a triple action for activation]..the cover being similar to the Cable Cutter or Intercom Failure Covers....
BHT [Medium Aircraft Tech Folk] in DFW had no problem with this idea, but still couldn't see [or admit] that they should also do it??
In the end it all got to hard, and nothing changed.
