So I've recently starting my ppl training and I'm finding it quite frustrating when my lesson gets cancelled due to bad weather. So far I had 4 lessons cancelled and only managed to log 2 hours! It's been asked before, but It's hard to find out what percentage of my lessons will be cancelled. So here's what I did:
Got all EGLL metars (I train in Denham) for the last 5 years. Filtered out those that are before 08:00 and after 17:00, then found the percentage each month of 'flyable' metars. What I consider flyable for training in a 152 (I might be completely off on this, so pls correct me...) is
And the average results of how many 'flyable' metar from EGLL in any given month from 2008 till 2012 are:
Jan 47.56%
Feb 45.14%
Mar 54.86%
Apr 68.69%
May 69.87%
Jun 74.62%
Jul 74.10%
Aug 67.80%
Sep 67.93%
Oct 64.11%
Nov 47.05%
Dec 53.89%
What you guys think? Do the above figures seem realistic?
