Mates,

If you want to keep a LR35 aloft for 05+30 you must dillgently flythe long range cruise profile and keep a sharp eye on RAT and ITT. Assuming a standard lapse rate, you can always climb 4,000 feet and only increase ITT by 20 degrees.

By the way, you can't do it if you come off the ground at 18,300 pounds, just the airplane 6,238 pounds of fuel and one or two pax.

A cargo company I flew for in the mid 1980's flew non-stop from KBUR-KTEB 4 nights a week and we regularly had 05+10 flight plans.

Also, 1,000 pounds planned landing fuel is fine.
