A Training Fix is what I the instructor ask for in the process of teaching you the student how to contact 121.5 in accordance with the the LOST procedure. You are not entitled to use it. Or in this case abuse it.
What a pompous, arrogant and thoroughly incorrect statement! CAP413 states:
Pilots who do not wish to carry out a practice emergency but only wish to confirm their position may request a ‘Training Fix’ on 121.5 MHz. This ‘Training Fix’ is secondary in importance to actual emergency calls but takes precedence over practice emergency calls in the event of simultaneous incidents.
Any pilot is entitled to ask for a Training Fix, instructor, student or otherwise. If such calls disturb WWW's quiet snooze in the driving cab of his airborne omnibus - tough!
