ummm yeah!!! realise that..
if you read the orginal thread the guy is asking why we dont! trim while airspeed is changing!
try to read between the lines a bit....
: "AS SPEED CHANGES WE NEED A CHANGE IN ATTITUDE >> WE NEED TO RE TRIM."
that is >>> re-trim (once you have set desired attitude as a result of airspeed change).... not trim why our attitude changes!
