Well, Learjets range in gross weight from 12,500 lbs to over 23,000 lbs. Weather conditions play a large part, as well. You'll have to be a lot more specific if you want a reasonably accurate answer.

Ok, I looked at some Learjet data, and it appears the short answer is probably not...particularly in a legal, safe manner. I'll let someone more qualified give you a more thorough answer, though.

I'm talking about a Learjet 31A.

Nope, the 31A can't do it. Not legally, anyway.

For a Lear 31, I do believe you can legally get one into a 2500' strip (part 91 that is - charter requires more runway), but the conditions must be right and the pucker factor would still be very high. Getting out is another story. You would have to be extremely light with only enough gas to get you to a very close airport and no passengers, it would have to be at a low elevation, and it would have to be cold. I know a guy who landed a 25 on a 2800' strip. If he can get one of those in there, you can get a 31 into 2500'. Barely.

It's been a while since I've flown a 31 so I can't remember any exact numbers off the top of my head.

I don't think I'd want to try it, though.

Thanks for clearing that up, Learpilot. I based my previous post on performance data in AWST's purchase planning handbook, which must not have fallen under part 91.

In case the original poster doesn't know what the guys mean by "legally":

If you're asking, can a Lear lift its wheels off the pavement less than 2500 ft from the start of takeoff roll, in favorable conditions with both engines working, then the answer likely is yes. So the question is: are you willing to bet your life both engines will work?

I used to fly a Lear 25, and anything less than 5000' required attention, special procedures, and a sharp look at the performance tables.
Just because I stopped arguing, doesn't mean I think you are right. It just means I gave up!

Quoting 2H4:

That's what I'm here for.  Big grin

What you may be seeing in AWST probably are the part 91 numbers under typical conditions with a couple of passengers (of course I can't tell you that until I were to see it myself). It takes into account crossing the threshold at I think 25 feet (I forgot the exact number - someone help me out). But to plop one into a 2500' strip definitelly wouldn't fall under "normal conditions". If you're 25' over the threshold, you better go around and try again - lest you end up in the grass at the far end of the runway.  Wow!
