LJ45 Questions...

[B1900FO]

Hey Gentlemen!

I searched through previous posts and did not find the answers I am looking for, so that is why you see another Lear 45 post.

For typical operating weights, what is the rate of climb in the 30's and even 40's?

I know there is a book profile, but what do you guys generally use for a climb profile?

Obviously, all other factors considered, will she still do .80 at FL450?

What are fuel burns typically in the 40's?

Had a conversation with another guy the other day about mid-size jets and we talked heavily about the 45 so I just had these curiousities. I've heard about the mx issues, but other than that I'm very impressed with the overall performance of the airplane. Thanks in advance for your answers!!!

-1500-2000 fpm climb in the 30's
- Climb speed 250-270 kts then .7-.74 mach
-.80 At 450 yes, and .81 sometimes (Indicated and also True Mach with ADC)
- FL450 1200-1250 lbs total per hour, depending on -+ ISA
- FL 430 @ 1300 lbs total per hour
-FL 410 @ 1340-1400 lbs total per hour
- I have seen 500 TAS at FL280 several times with ISA +19 temps

It's not that great, don't get too excited. The ONLY thing good about the 40/45 is the acceleration at altitude when you level off. And, that's only in the BR engine. Other than that, the plane blows in my opinion.

Any of you guys want to sell your Lear 45 manuals??
