i'm with the contract dog on this one, APTRAC are a good bunch. and sorry if you think i'm promoting bad airmanship SRT but i'm not. i was in a similar school and a lot of taxing was involved, that i was expected to pay for when moving the aerie around the apron. so i was shown a simple trick and it saved me a few bucks. i don't know enough about pressure switches and oil lines and frankly couldn't care less at this stage of my flying. but it worked for me, i was also an instructor and would NEVER condone a student doing this but he might just have got his couple hundred rand back from the bull
cancellation fee trick they try and pull.
anyway, the point of the thread was to help this youngster out, and that's all i was doing. buddy, if things don't come right where you are, don't hesitate to move on. you'll see later that it all builds into your experience. they need you more that you need them although it may not seem so and they certainly would never want you to think that.
