Flying the Lear 35A - By the Numbers?

Recommended Posts

Hey all, sorry to bother again with fuel burn numbers but I was wondering if the staff could maybe post the typical fuel burn numbers for this aircraft kind of like the sticky for the Conquest II. 

 

1st hour, 2nd, 3rd, + 45 min IFR reserve?

 

Would make flight planning a heck of a lot easier!

 

Please, and thank you!

Hey Luis,

 

One of the revisions in the next update will be to the fuel flow. At present, it isnt as accurate as it could be. 

 

Fuel consumption in the Lear, both in real life and in our sim, is extremely dependent on the altitude you're using for the trip. The trick with the Lear is to get it as high as you can, as fast as you can. Down low they burn an obnoxious amount of fuel. The turbofan powered 30 series airplanes are a tad more fuel friendly at lower altitudes in comparison to the earlier turbojet powered Lear's, but this is a relative statement. You want to flight plan for the highest practical usable altitude for the given trip. Assuming you get it up into the FL400-FL500 range, you can expect to burn anywhere from 1500-1800lbs in the first hour, and around 1000lbs per hour for every hour thereafter.

 

In terms of reserves, try not to land with anything less than 1500lbs on the airplane. If you're low and slow with the power pulled back, it will be more than an hour of fuel which should allow you to set up a second instrument approach or proceed to an alternate.

Thanks for those numbers, very helpful and a good reference!
