Citation VII numbers

[THE Flying Ace]

This has been posted on the corporate side, but I know you netjets guys operate the VII.

Those of you who are operating the Citation VII, could you please give me some performance numbers on it.

Departing elevation 906, 3909 runway, and I assume flaps 20 would be the best config for the short runway. How much in fuel (hrs) for given situation?

1. 10, 20, 30 celsius
2. 500 and 1000 lbs payload
3. no required gradient


Thank you

The 7's went the way of the dodo bird at NJA, they are gone. Maybe some guys that remember them hanging around though.

Ah, didn't know that. I guess it has been 3 or 4 years since I was talking with a 7 crew out in NJ.

Thanks

If I remember correctly, I think the NJA VII BOW was around 15,100 lbs.
I don't have the books with me but based on a cheat sheet I have for your conditions, the runway required is approximately:

19,000lbs @ 10 degrees = 3,900'
18,500 @ 20 degrees = 3,970' (15 degrees would work at this weight)
18,000 @ 20 degrees = 3,790' (25 degrees also works at this weight)
17,500 @ 30 degrees = 3,895'

I think a rough estimate for 1st hour fuel burn was around 2,500 lbs for a fully loaded aircraft. Hope that helps.

Before you crunch numbers I would call the insurance company.. It is doubtful that they will cover the hull operating out of 3900 ft. I may be wrong but I would start there. That being said and without the books in front of me around 19,000 lbs is where the aircraft will become critical. With typical Bow's around 15,500 add in a few passengers and bags you will be doing lots of pacs off take offs with enough fuel for 1-1.5 hrs with reserve.

Have most of my time in the Citation III which had similiar numbers ( slightly less power 3650 per side but lighter as well ) And did some contract work on a VII out of a 4200 ft strip in MI.. Remember one trip in particular going to VRB with 6 pax and a dog., Departed around 12 degrees and climbed up to FL450.. Coordinated with ATC to stay up at altitude and then did an unrestriced descent to land with legal reserves. Winds were favorable, isa - 6, pulled back to .78, and started down only about 80 miles out.. Burning about 680 lbs per side at 450..

Hope this helps a little.. My advice buy a used excel there are quite a few on the market currently

I kind of thought that the 650 series would be tough, but I had a guy flying a 7 that said no problem operating from 3900ft and flying 2-3 hrs. Wasn't sure if he was right or just off a little on his numbers.
