Is there not a requirement to perform a full iteration of your display routine at fixed intervals throughout a display season?
I may well be wrong but I had the feeling that In Season Practices had to be weekly/fortnightly to ensure you are 'current' for the display routine?
I'm pretty sure this applies to Military displays? The reds often talk about ISP's during their quieter times in the display season to remain current. I also believe that this years Typhoon Display pilot had to perform ISP's after the end of the UK/European display season as he had a Far East commitment late in 2015?
Does this not apply to civilian operators?
