October 23, 200223 yr Hi,having seen many 757 FMCs being programmed in real life, I have started to incorporate the following VNAV CLIMB restriction into my FMC setup - V2 + 80 knots / 3000 ft AGL. This takes you to the clean speed, but can't remember if it's MAX RATE or MAX ANGLE of climb it gives you. Then in VNAV passing 3000ft AGL, speed automatically increases to the 250 below 10000ft rule.Mark
October 24, 200223 yr I do. I spoke to a Continental 737 pilot friend about this once, and I think I recall him saying they usually put 210/3000 or something to that effect in the speed restriction box.I also do this on the VNAV DES page, otherwise you will end up flying at 250 all the way down below 10,000 (although by that time you are usually flying in some other mode than VNAV :-))Damon
October 24, 200223 yr I used to teach FMS operation at northwest and there is only one time that we put anything in to the speed restriction page. If we are doing close in community departure, where we do not want to clean up the flaps until above 3000 agl. Then we put v2+15/3000 in. Actually there is an ever easier way to do this, but PIC does not simulate it. In the 757, the takeoff page has a place on the left to put an acceleration altitude and then it will calculate the v2+ 15 by it self, so if it changes the pilot does not have to update the climb page. There is no reason to put 210/3000, because as soon as the flaps go from 15 to 5, the speed bug moves up to the flaps 5 speed limit, and it keeps doing this until the flaps are up and then the bug goes to 250, until 10k and then up to cruise speed.
