Hi all, 😀

Would someone kindly tell me what MCT and MCR stand for on the Lear throttle area? TIA !

I believe, (and I will be corrected) that they mean this.
MCT -Max continuous (climb) thrust.
MCR- Max cruise rate.

Nope, Rararman's right!

what seems odd though is that the APP setting is higher than the T/O setting on there, who in their right mind would approach at full throttle?

Unless APP means something else?
Radarman, whats it mean?

F_E_M,
This will mean more to you than me, I'm not to up on this as of yet.
*************************

In commercial transports the usual philosophy is to attempt a continuous descent so as to fly from from the FAF (Final App. Fix) to the MAP (Missed App. Point) in a stabilised config, i.e. speed, config, thrust setting, descent rate etc. all constant.

The old accepted method, still required to be followed in some instances due to obstructions, and traditionally taught in the early stages of one's instrument training in light aircraft, involves a series of stepdowns, and minimum altitudes/heights at set distances. This will probably involve descending to and levelling out at a minimum descent altitude/height (MDA/H), before reaching the MAP. and arguably increases the chances of seeing the runway in marginal conditions

This one for Fire_Emblem_Master.

I am looking at your picture and I cannot tell if you need to get more sun, or, you have gotten too much sun. Weird huh? 😕

Lemme tell ya, if that was me, i would hide. Actually, i think it's Till Lindeman, from Rammstien.

Since Nobody knew what what the "Approach" region on the throttle quadrant was, I thought I would bring back this 3 year old post for everyones general information. The farthest marking on the pedestal is not APP its APR. This has ABSOLOUTLEY NOTHING to do with the word approach. I am a student on the Learjet 60. Markings are the same. APR is a mode that is only used in the event of an engine failure, or full aerodynamic stall recovery. Basically, what the T/O region does, is bring up the power, and then tweak it a little so that you are generating the maximum allowed power for the current conditions. This is all done by EDC computer. Well, APR mode does as follows: lets say that you have just rotated, retracted the gear, and your left engine fails. When you push the Right throttle into the APR region, It overrides the EDC computer, and generated Sea Level power with the good engine all the way up to 8000 feet. This means that you get a tremendous boost of power to keep you going. It should only be used in emergency situations. Most stalls only require a small input of power in a jet to fly out of them.

That thread is 3 years old and half the people that made it left the forums! 😉

.....nevertheless, assuming what's posted is correct, it was interesting to me to read 🙂

I agree with you, sometimes guests dig up these ancient threads and intrest us in a topic that's important but never thought about it! 🍻
