Citation Descent Profiles
I found a copy online of th Citation Bravo flight planning guide. In it, it lists 2 descent profiles. High and low speed.
For planning purposes, getting the max range, which one is used. Interestingly, the fuel flow on the descent works out pretty much the same as the long range cruise fuel flow per hr. is that due to them not using idle power for the decent as the large jets do, think its for door seal inflation? Do te newer CJ series use idle power for descents? |
3 miles per thousand is a good starting point for ANY jet!! dbee:ok:

Hello!

Door seals
what next:
I do not know about the Bravo but some eariler business jets at high altitude used to lack sufficient bleed air to stop the cabin altitude from climbing with throttles at flight idle. At low level, no problem. It is good procedure to keep aware of how your cabin altitude is behaving Tmb |
Hello, I use the normal 2,000 fpm, which at TOD will give you about 3.2 degrees descent angle. It is efficient fuel wise and comfortable for the passengers. 3,000 fpm is to steep.
You will not use idle power in the descent in a bravo because it is no a sleek airplane, you need power to keep your speed at near VMO in a normal descent, if not, the airplane slows down too much (straight subsonic wing). The two seals in the citation bravo doors will keep the airplane pressurized in any descent regime without any problems, the auto press controller works marvels, even at descents of 4,000-5,000 fpm. |
