iPad
I used to fly for a freight company in my last life, and we had a similiar EFB program onboard (before iPad was even invented).
The reason why you don't get the little "triangle" or "hang-glider" (as we used to call it) on the IAP, is because it is not a scale picture. The "triangle" can be represented on an en-route chart or airport chart because they are to scale..... the IAP is not.
Enjoy it... it's a great tool..... but remember... it's a tool... you are a pilot.... look outside or at the instruments provided.
