Not picking on you John, but I’ve got over 3000 hours of Learjet time, and the GE powered jets (25’s to be specific) are best flight planned at 22/20/18. Don’t pull them back to idle at 390 or 410 unless you knew you had landing weather above mins. You’re thinking of 35 numbers. 15/12/11/10/10.

N1965L was born a 23 but is now technically a 24. I’ve flown that jet. When people say 500 mile an hour twin Comanche, that’s the one they’re talking about.

I do think that we planned 20/15/12/0 for the 23s that we flew, and yeah, once you start down you're landing somewhere. I think the difference between your 25 numbers and mine are due to the weight of the 25 being higher than the 23.

Pull them back too far up high and you lose the cabin pressure At least in the several I flew.

If you wadded up a paper towel soaked in water and spread it out over the leak it would freeze and seal up. The boss eventually broke down and got a new door seal.

Here’s a shot of N1965L at Van Nuys back in the day. No captions need for the two gentlemen.
It should be noted that Frank’s mother was killed when his 23 (N9FS) CFIT’d into Mt. San Jacinto with his pilots trying to pick up their IFR clearance.

Don’t pull them back to idle at 390 or 410 unless you knew you had landing weather above mins. Those numbers are very similar to the P&W JT-12 powered Sabreliners. Similar flight profile, albeit with less climb performance than the Lears. Climb as high as possible, as quickly as possible, and descend as late as possible. Fuel flows on takeoff or go-arounds would cause your eyes to bug out... Those Jurassic jets were a blast to fly! Greg
