For the line check airmen/women of the board:
What's the most useful advice you could pass on to someone who may be new to instructing/who was never a CFI? A friend thinks he's capable of such tasks and has been reading up quite a bit on FOI etc but still has some doubts, outside of the mentoring of normal line FOs he has no experience teaching in an airplane.
Hopefully on IOE you aren’t “teaching”. You’ll be sharing experience and letting them get a feel for the plane, however they “should” know what they’re supposed to be doing.
You’ll have to observe a few legs of IOE, and then “Give IOE to the check airman”. After that you get to wreck your own souls.
Start with a solid brief. Seriously walk them through walking on the plane to walking off. Tell them exactly what you expect them to do do. Chair fly them through a departure on the line vs. sim departure. Brief the hot topics, and gotchas. Expect them to be way behind the plane on leg one. When you safely can, tell them exactly what your doing as you do it- and why.
Day 1-2 you’ll be coaching a lot.
After that they need to start doing it themselves. They should have a fee for timing, and shouldn’t need to be prompted for normal duties.
You’re not going to sign them off as full fledged 100% competent pilots. They’ll still be green, and still make mistakes. Once they start to realize their mistakes, generally they’re gtg.
Once you really get comfortable, I found it was actually easier if I gave them the first leg. Reason being, they come out of the sim VERY proficient at flying profiles. SID to a STAR to an ILS to a landing is what they currently rock at. Radios, timing, non sim procedure is where they are weak. Letting them fly the plane without having to worry about the rest, while getting to see the rest frequently made it easier. Just be ready to take the airplane back, and if your do- remember to remind them that it’s ok- that’s your job.
Good luck!
