You didn't answer my question about what climbs at .75. Thats alot better than our little ERJ can do. So how if your profile is .75 and mine is .56 would that do anything for ATC. If anything I think it will piss ATC off as your gonna be coming up behine me pretty fast. I try to get close to redline (250 below 10) and around 310 after and that will give you between 2000 and 3000fpm depending on altitude. Then turn on the VS or Speed Mode and let it do its thing. Like I said I don't know what you are flying but in the ERJ it is easy to hand fly and most all the captains I fly with hand fly it up, some fly faster, some climb faster. And nothing is ever done that would be violating any FAR or limitation on the aircraft, just sometimes it would be impractical and stupid to do .56 all the way up to 35,000 ft. So take it how you want to but sometimes you have to be a pilot and make a decision on your own.

At my airline it's either 250/290/.60 or 250/290/.65 depending on the aircraft type.

If I'm overweight or running behind schedule I may ask ATC permission to climb at 600 fpm which will burn a few extra pounds and get you there a few minutes faster most of the time. Occasions where I do that are very rare. I'm sure in the citiation 600 fpm will put you through redline, but on a full RJ it will give you somewhere in the neighborhood of 300/.70M.

Most of the mainline jets seem to climb at barber pole (or close to it) from my experience in the j/s.
Per our climb profile: 240 below 10,000 then .56 above 10,000. And it states that these are just Manufacturers Profiles.
