Sultan noted the Accident Report did not discuss the Engine PCL's being on the Overhead Panel being a detriment as compared to the Collective mounted Throttles on Bell Helicopters.
This does highlight the benefits of collective mounted throttles like on Bells.
Many aircraft have "Levers", "Buttons", "Knobs" instead of the Bell Collective Throttles.
With the advent of electronic digital control systems we see new and different methods of controlling the Engine(s) as compared to legacy systems using electro-mechanical means.
I have flown several different aircraft with various approaches to Engine Control....and have seen advantages and disadvantages in all of them.
So what should be the determining factor in which design method is employed?
One look at a V-22 Thrust Lever and I shudder to think what engineering issues and human factor issues would have to be confronted to move the PCL's from the overhead Panel to the Thrust Lever.
As it is now....they are moved to the Fllght position not touched until Shutdown of an Engine or Engines.
