(Couldn't get this bloody Firefox junk to cut and paste!)
How difficult, Impiger? Well, here are a few essentials:
1. Speak your mind and don't let pilots do something stupid. You're well qualified there, mate!
2. Speak your mind when some pratt of a senior officer tries to reinvent the wheel you've seen thousands of times before...... But you won't have got to your current lofty status having done much of that!
3. An ability to trap the ugliest old moose imagineable when down route. Neither you nor, indeed, haltonapp meet that requirement. But I know a few who do!
Otherwise take a look at JAR-FCL 4 and it'll tell you all you wish to know - and a lot more besides.....
