Flying c/v
Flying light aircraft and helicopters is on my c/v under interests and hobbies although I don't expect to gain a job which relies on either. It is, though, an indication of an ability to learn a complex skill and subject which is valuable alongside more formal learning. It is also a different subject for an interviewer to refer to in order to develop conversation. The most valuable bit though (and I am in a position where I have interviewed many people for jobs) is that it is something by which you can be remembered. This additional memory jogger for an interviewer might be what makes the difference between being called back or ignored.
I have been in the fortunate position to have flown to interviews in the past and this certainly lends a certain something to the struggle to move up the priority list.
What do you have to lose.
You might even come up in front of an interviewer who also flies and form a 'bonus bond' which can help. Not all interviewers are expert and detached in their decision making sad statement though that it.
