Give and take, and take ....
Annoying, duplicitous and down right anti-safety they may be, but stupid......... not always.
Add 25 minutes to the report time and then stand up and tell the industry and wider world what a wonderful caring safe operation they have, accurately reflecting pre-flight duties with a more sensible report time.......... but introduce Variation 4 allowing an extra 60 minutes to be added to the FDP limit, and hang on, that's just more than cancelled out that earlier report time.
Honestly, you couldn't make this stuff up.
In no way do the associated restrictions on this Variation 4 make up for the extra duty time permitted. Once again, it's down to the individual Commander to manage. Go over the new limit, and it's your discretion, should you choose to use it.........
