Falcon 50 info

[knelson]

I am sure there has been plenty of info on this board before, but I only have so many days I can read, so. . . thanks in advance for the replies.

I have heard great things about Falcon 50 performance figures, but not too many hard numbers.

The airport in question is a 3300ft elev. 5000ft rwy that routinely gets to 95 degrees in mid-summer.

I am curious if you can get the 50 light enough to make it work (takeoff performance part 91) from said airport or if it is just out of question. Thanks again for the help

Absolutely you can get it out of there... I can't say how far you can go as I don't have straight 50 numbers, but a 50EX can go about 3 1/2 hours range out of those conditions. My guess is a straight 50 would do about 3 hours or so... If you load it full of people (8 pax) shorten that by about 45 mins each aircraft.

I used:

3,300 ft elevation
29.92" hg
95°F (35°C)
5,000 ft. runway length

Results (50EX):
32,410 lb. take-off weight (22,000 - 22,500 lbs is typical BOWs)
4.8% second segment climb gradient

Not sure what kind of climb gradient you are looking for but....

I think the question is more like - what business jets CANT get out of there with a few hours of fuel?

95 degrees is a bit warm but 5000ft at 3300 elevation is not TOO challenging to get out of under MOST conditions.

What business jets can't?

As far as mid-size business jets, I am not aware of a whole lot of aircraft that will. Citation 3, 6, 7, 10, lots of swept wing light jets, (Falcon 10, BE400, some 20 series Lears).

But anyway, for the money, the straight 50 looks like a smokin' deal. I have not seen a lot of maintenance numbers, but I am sure that extra engine does a trick to the bottom line. Can anyone provide basic info on hourly fuel burn on a straight 50?

Thanks for the replies guys, I do appreciate it.

"Basic" fuel burn in a straight 50? Figure 3000# the first hour, 2500# the second, and roughly 2000-2200 each hour after that. This is the gouge for a 260kt/.72m climb and typical cruise of .80m. Not real scientific but for a quick answer it works out 95% of the time. PM me if you need more info.

Here are numbers from my ultranav. 33500 MTOW, 5.1% climb gradient. Thats with the BFL at 5000 ft. Our BOW is 22600, so that leaves 10900 payload. Thats 4 hours of fuel plus reserves and you can go to 380 or 390 directly. We figure 2800 first hour, 2600 second, then 2000 for every hour above 370.No passengers of course.

I've heard its actually very rare to get a Falcon 50 to its max takeoff weight, even with full fuel and pax. Is this true? What kind of runway does it need at MTOW, assuming sea level and standard temp?

I take off at 40780 lbs from a 5796 ft runway at 800 ft elevation about once a month. We are always able to get a BFL that is less than 90% of that runway (which our operation requires). That is in a 50EX. I don't know anything about a straight 50's performance.

 

[Kingairrick]

Straight 50:
BFL 5180ft
GCG: 4.9 %

sea level, 0 wind, 0 slope, std temp, max gross to (40,780)

Pardon the ignorance, but where can I find the Ultra Nav program for a Falcon 50? Thanks again for all the responses.

There is your ultra nav link.

Got to tell ya,,, those are some very impressive performance numbers. Did our French brethren get it right,, or is it just them good old smaaart and skillful American pilots??

 

[knelson]

Small world, Ultra-Nav's shop is about a 10 minute drive from my house. Thanks to all who have responded. I am really impressed with those numbers! Hope to get in one some day.

Anybody have any general opperating costs on the straight 50?! Performance #'s look good and fuel burn is pretty striaght forward, but how about the schedualed/unschedualde maintenance. Is it a maintenance hog? How high is the vertical stab? (for hanger reasons)

 

[Kingairrick]

Vert. stab is 22'10" with no satcom dome. We fly ours 400-500 hours a year, very little time in the shop. We have in-house maint. dept to handle litle things...Don't have a clue about DOC's except for Conklin & dedecker...They say:
$1905......50
$1647.......50-40 (retrofit)
$1500.......50EX

As far as the prf. numbers. Unfortunately, the French just got it right. A monkey can fly it, and beat the book performance numbers every time...Of course, I'm still workin' on it.

 

[knelson]

50-40

What exactly is the 50-40 retrofit?

 

[knelson]

guess I could have done a little legwork!

a short google search answered my own question, for those interested, here's the link
