Hi Jane,
See me earlier reply.
'Turn' - by the very nature of vectoring, is given at an appropriate time, and does not delay our progress (unless it's one of those French 60degree jobbies to allow Air France to carry on without changing course).
'Climb' - well, we're not going to say no! You will know that our engines are most efficient at altitude, so we always want to be as high as we can (weight plays a small part here, as may very strong winds).
'Descend' - equivalent to 'get there later and burn more fuel'. In the circumstances you describe, we'll either use Vertical Speed mode to achieve 500fpm until on the desired profile to just make the restriction,followed by idle power descent, or use VNAV in 'Capture' mode, which will give a 1000fpm descent until on the profile, then ide power descent, or use level change/open descent to give the least efficient idle power descent to the cleared level. Most pilots will not do this last one. 1500fpm is not stated anywhere as a standard rate of descent.
