Both of the pilots are MEI's, and I have logged some dual received with them. Im not looking to keep this job forever, just for a few months to get a little multi time build up.
If thats the case you can only log the time if you are ME rated. If so, then all of that time has to be 'dual recived.' You cant log total time if you do not log either PIC, SIC, or dual. If you are just flying the plane (logginn total time), and not reciving dual (whch yyou cant do), then you must have your high altitude endorcment, if the A/C is certified above flight level 250 (i thinks it's 250).
