ultrarunner said:Wrong question Pin....
the question is:
"...what is the better company to work for...?"
I've got 3000 hours in a 35 and they won't fly 460 to 470. Perhaps 430 to 440.CapnVegetto said:The lear does 460 to 470, and the Encore tops out at 440.

Thanks.

I agree with you. FL250 is the optimum altitude in a 35 if you're looking for speed, but it's hardy the most efficient altitude. The only way you're going to be seeing more than 440 KTAS at 370 or higher is if you disregard the published engine limitations in the AFM.Capthuff said:the only time I see 460kts is in the low 30s, in the 40s you'll see 440 or so...

CapnVegetto said:What did you run it at? Straight out of the book 795 degrees ITT for max cruise is what we ran it at. 460 almost every time at 370.
Edit: Also had DEECs instead of EECs on ours, so the engines performed a little better than on the older ones. With the DEECs turned off the power output of the engine was noticably less. 795 ITT got you a LOT less N1 without DEECs than with.
That's the case with any jet aircraft. Best #s are going to be in the 30s. Citation X for example won't see a hint of .92 in the 40s, but if you have to get there and need the speed, drop in down into the 30s and hang on. Efficiency of the fan drops of considerably when in the 40s, but it does not have to work as hard, so the fuel #s go way down.Capthuff said:the only time I see 460kts is in the low 30s, in the 40s you'll see 440 or so...
You were light, it was very cold, you had an unrestricted climb, and when you arrived at TOC, the 31 was on it tail and not on speed. I think what CaptV is trying to say is proven here in your statement. You made it to 43 in 17 and that is some sort of record. In the Encore with the P&Ws, that is just another day at the office; not a big deal. The LR60 will do that all day long and it has a little stronger version of the same P&Ws the Encore has. Garretts are nice, but at the end of the day, they get romped by the Pratts. Falcon moved away from the Garretts on the 7X and F2th and put P&Ws on them. The 2000DX is at 410 in 17 minutes and that is a normal profile. The 7X is their flag ship, and the trusted Pratt to get the job done and they are getting better than expected performace out of the airplane, so much so that they are considering putting winglets on the 7X to eek even more performance out of it. Next time you see a LR60 or Encore taking off, stand out there and listen. It is much quieter than the Garretts; be sure to go to the 1st 1/4th of the runway, cause they dont need much to get airborne.Capthuff said:you made it to 230 in 5 minutes? so what - you're still in the trop. try getting to 430 in 17 minutes. thats my best time in the 31
You are selling the 31 cause the boss figured out it has no range. The 40/45 still have Garretts on them, so it might have a little bigger interior, but it will by no means out perform the Encore. It has more range than the Encore, but in terms or raw performance, the Encore has is beats. Bombardier took a plug out of the 45 and called it a 40 along with a few other changes, but that plug they took out of it was the only part of the 45 that worked properly. The month long 45 fleet grounding was also a welcomed surprise I am sure. Go fly something that has P&Ws on it, and you'll be singing a different tune.Capthuff said:But I do believe that overall the Citation is a better product than the 30 series Lear. But the 40/45 has them both beat by a mile. That is why we are selling the 31 and getting a 45.
a nice Christmas present for me.
some_dude said:More relevant is what mach you were running at. TAS will vary with temp.
And, when calculating TAS, did you remember to take into account the mach error on the non-Rosemount probe Lears?
As for the job question, like everyone else said, choice of airplane is very much secondary to quality of company and job.
It may be time for a thread on powerplant management, but not today...CapnVegetto said:What did you run it at? Straight out of the book 795 degrees ITT for max cruise is what we ran it at. 460 almost every time at 370.
