Filing a formation flight plan

[Sam Rutherford]

We have been using formation flight plans more and more over the last couple of years, which works very well.

One thing I have noticed is a huge variation in what controllers/Navigation Office personnel expect on there, particularly separation by aircraft (or not) for:

Callsigns, types, POB/aircraft, Endurance/colour etc:

Does anyone have the definitive guide for filing a VFR formation flight plan?

Thanks, Sam.
