1-3. Absolutely no housing for cadet at the moment. Special management allowance when promoted to captain which is around 1/3 of the housing allowance and 1/5 of the present rental allowance for captain. Local employed pilots are getting now an education allowance as far as I know, so cadets will get it too.
7. SO do not take-off or land the aircraft. SO operate the radio and maintain fuel log in cruise. When flying with Captain SO sits in right seat when flying with Relief Qualified FO, SO sits in left seat. SO time can not be logged, as you will have a P2X rating.
