Just a quick question, it has been mentioned on this thred about using speed to correct the profile (too high). Good idea above 10,000ft. Below 10,000ft options are suddenly running out, someone commented on using speed to correct the proflile in a low alt (below 10K) situation because if your high you have to much energy, ok so far. Now your back on profile but about 70kts too fast, havent you just changed to type of energy you have? you are still in a situation of too much energy, but now a few thousand feet lower. If you are fast what are your options? Speedbrake, more track miles to run. If you are high? flap, gear, speedbrake and more track miles to run are all options to help the situation.
Its best to be on speed and on profile, but as we all know ATC get in the way. In our company the managment have decided that it is best to be high on the profile but slow, with plenty of options at correction, than fast but at the correct alt with limited options at corrections and with the constant threat of "direct centre fix" coming over the airwaves.
What Im trying to say is if your fast, you cannot get gear and flap down, and to slow down your going to have to go high on the profile. Is it not best to do this early, say around the 10K mark, than just before you capture the glide slope?
B757, gear down, flap 30 = Six degree glide slope, this will get you out of most high on the profile situations at low altitude.
Dont mean to be patronising, sorry!!!!
