Just come across this thread.... I am a D&D controller & recently qualified PPL. Just to reiterate what the others have said from the horses mouth as it were.
If you ever begin to get an uneasy feeling about your nav call us sooner rather than later, that is part of the reason we are here. However as someone said earlier, if you are lost, say you are lost. If you just call for a training fix we will tell you where you are (although perhaps we wont if we have a real emegency on) and then move you on sharpish. However if you say you are lost we will stay with you until we have got you back into a position where you are 100% happy with where you are.
Have you called 121.5 for a training fix or a practice pan during your training? If not i would suggest you speak to your FI and give us a call so that you become comfortable with the use of 121.5....... we are here to help.
