I am not on the Scholarships Committee but I know there were almost 400 applications for scholarships for which the deadline was 17 March (PPL, Gliding and FI).
All the work from initial sift through to interviews and final decisions is done by very experienced people who are volunteers doing it in their spare time.
Processing 400 applications obviously takes time to complete.
I'm not certain but I don't think confirmations of receipt are sent out.
I think the next stage is applicants being told whether or not they have been selected for interview.
Good luck.
