This may be the exact same contract that I was instructing under when I was an instructor. However, my flight school has gotten greedy and since I left has been losing these contracts.
If Sierra has the contracts we used to have, it will be a great opportunity for instructors wishing to build time quick. My first day instructing the contracted students I was handed 4 Air China guys (on top of my 10! domestic students) and it was off and running...flew about 7 hours a day when the weather was nice....if it got crappy, we "visualized" on the white board for the entire 14 hr duty day. You will fly bunches.
The tough parts:
1) HORRIBLE ENGLISH!! It is tough to explain pitch angle and such for straight and level flight on the first lesson when you first must explain what a HORIZON is! And what you mean when you say sky, ground, angle, pitch, elevator, up, down, yes, no....etc.. Doing it while they are nervous, and talking through a crackling intercom over an engine at 2500rpm makes it even worse
2) The Chinese students will say "yes sir" to everything...whether they understand you or not. Making the question, "do you understand?" irrelavent. You have to make them show you.
3) Our students had never driven a car in China, so the normal hand-eye coordination most students have is not there. Does make it easy to teach taxiing. (no pre-programed muscle memory on how to turn a vehicle)
4) Finishing quickly was a matter of pride within their class. So sometimes they didn't want to learn the finer points. Tough to get them to listen sometimes.
5) Some of the toughest instructing you will ever do!!
But it is flying...a lot. So it is worth it. These students already have degrees in Engineering and Physics and stuff, so they are smart...and motivated. Just not the most prone to flying, the term "duck out of water" comes to mind.
Just the other day I recieved an email from a former student. He just finished his A320 training and is now observing for a year until he takes the right seat. Pretty cool to know that I planted the basics in him...now he is flying a 320.
You will be frustrated...but keep it fun and pray you get a student with decent english skills.
