Lu,
Lets clear up some of your misunderstanding of what you read.
Early on in this thread....I corrected one of your posts by clearly stating the concept was "differential collective pitch....DCP". You come late with that excerpt from the manual or what ever you are reading from.
You mix two systems up here...the normal hydraulic controlled and operated flight controls and the electrically operated Speed Trim System.
Lu, if you switch the Speed Trims off.....they do not operate....the speed trim system is inoperative...the aircraft is Vne limited...greatly limited. But Lu, the hydraulic flight controls continue working normally.
Two independent systems Lu....nothing to do with each other at all.
Lu...where do you come up with the idea that anyone said the two rotor heads moved cyclically in movements of the cyclic stick in a fore and aft direction. Are you not the one that stated "the pilot cannot input forward cyclic"?
Also Lu, when the speed trims function...there is no coorelation to Thrust Lever position....any reduction, if any of Thrust Lever position,is not noticeable and since the speed trim actuators are moving as the aircraft is accelerating...the only Thrust Lever reduction would be as a triming effort by the pilot to achieve a desired airspeed/altitude combination. Thrust Lever Lu is the correct nomenclature for the "collective lever" .
I know the Chinook is a bit more complicated than a Robinson...and according to several posters you had some problems with that rotorhead....but Lu....read and quote from all of the pertinent sections of the manual if you are going to do so. Be thorough in your submissions.
