It's not a regular check anyway and isn't done on a daily servicing basis.
Has anyone got more complete information on this ?
From my time on Nimrods, I seem to remember doing 'pull off' checks with a device that checked that the probe would leave the drogue properly. This was done before every scheduled AAR trip.
I also remember the sumpys doing refuels through the probe, bowser hose went up a set of aircraft steps and onto an adaptor on the probe. I don't remember whether this was part of sceduled maintenance/OOP etc, or whether done before an AAR sortie. This was on the R fleet.
