Pub User , quite agree to what you say , since the eng hyd pumps operate as long as the eng is operating . And theres no way to turn them off with an eng operating , so wouldnt be much of a point having an indication .
Mig15 your explaination is very logical , dont think the main gear would compress 4 feet , thats a bit too much I say too .
Imbracablecrunk , the CFM 56 flat rating is ISA + 15 c = 30 c . I have fed assumed lesser than that ample number of times . Try it out when conditions permit , or may be assume an example just to check it out ..
Jet737ng , about the flap speed , you mean to say that if the actual flap 25 speed is within 4 knots of vref 30 , it wont display , is that correct ?
The only way to figure out flap 25 speed would be vref 40 + 10 , right ?
