Like others here, I send my congratulations to IO540. He has really taken a lot of his time to share his wealth of knowledge and experience to all. His posts are very interesting to read and invaluable to the pilot community. From aircraft ownership and maintenance to flying tips and techniques, to flight planning, weather planning and safety. So a huge thank you!
In a constructive spirit, my only criticism of him is that when it comes to areas of advocacy he can turn a little bit defeatist and make some things seem much harder than they really are to achieve.
But overall, I have no hesitation in recommending him for the next round of the UK's CAA General Aviation Safety Awards and to nominate him for a senior position in AOPA if he is not already on there.
