Citation II performance question.

[CaptainProp]

I know close to nothing about Citations and I would appreciate if you guys with Citation experience could help me out...

Does operating a Citation IISP in and out of a 3000' runway, in temperatures up to 30-35 degrees, sound like something you would / could do regularly?

Thanks!

What payload? What elevation? Commercial or privat?

Edit: found my old FSI 550/551 Checklist:

Numbers for 15 ° Flaps / 20°C / SL: MTOW for the IISP is 12500lbs...
T/O LDR unfactored
13300lbs 3270ft 2430ft
12000lbs 2640ft 2230ft
11000lbs 2240ft 2130ft


Numbers for 15 ° Flaps / 30°C / SL:

13300lbs 4010ft 2530ft
12000lbs 3080ft 2270ft
11000lbs 2560ft 2160ft

Numbers for 40°C / SL

13300lbs 4750ft 2630ft
12000lbs 3740ft 2420ft
11000lbs 3020ft 2200ft

Numbers for 20°C / 1000ft:

13300lbs 3380ft 2540ft
12000lbs 2840ft 2270ft
11000lbs 2400ft 2170ft

Numbers for 30°C / 1000ft:

13300lbs 4290ft 2650ft
12000lbs 3350ft 2310ft
11000lbs 2740ft 2210ft

Numbers for 40°C / 1000ft

13300lbs 5330ft 2770ft
12000lbs 4080ft 2350ft
11000lbs 3280ft 2240ft

I don´t recall the MLW, I think it was something like 11800lbs?

For 1,67, the LDR should be 1796 ft or less. So no joy there. 1,25 - what we use in our coorperate FD would require 2400, thats no prob I´d say.

[CaptainProp]

Sorry. Not commercial, less than 500' airport elevation, pilot + 2 pax and little or no luggage.

[His dudeness]

I´m trying, but I really can´t recall the empty or bow of the sled I flew.
Has someone got numbers available?

[FlyingGasMain]

We fly Citation IIs on an AOC and 3000' sounds very unlikely if you are applying commercial safety factors. I think those FSI figures given above should give you a pretty good idea for unfactored operation

[CaptainProp]

Thanks for your replies so far!

I have received more info on the specific aircraft now.

Basic empty: 8200

MTOW 12.500 lbs (Ramp 12.700)

MLW 12.000 lbs

Looks like operating single pilot, 2 pax, no bags, allows just under 4000 lbs of fuel to be carried and the limitation (T/O unfactored) would be about 20˚C.

How far would one get with 4000 lbs of fuel with one of these things? If its 30˚C, how far would 3000 lbs of fuel take you?

A rough idea would be appreciated.

Thanks again!

Fuel planning figures are 1200lbs for the first hour, 900lbs each subsequent hour.

So - plan on 3000lbs giving you 600nm plus holding plus diversion, 4000lb will give you 900nm. Figures are approximate but you won't get "caught short" using these.

[His dudeness]

Just to make it clear, the T/O figures are FAR 25 figures, so its the longest of
ACC-GO, ACC-STOP or All Eng TOD by 1,15.
Landing figures (the figures on the right coloum) are without factor.

As for the landing, if the runway is grooved thaat would be a real good thing, ours (LDA 3323ft / C680) is grooved and that makes a biiiiig difference.
Has the airplane T/Rs? IIRC there are some CIISPs without them to save weight...

[BestAviation]

Just to make it clear, the T/O figures are FAR 25 figures, so its the longest of
ACC-GO, ACC-STOP or All Eng TOD by 1,15.

With the exception of a very few scenarios (hot/high) the higher number is the ACC-STOP distance in the Citation II. Don't think I'd use that information for anything practical though.
