Welshpool
Welshpool has a hold called Charlie at one end of their runway. To get to the hold requires a back-track of the runway, pulling off at the end onto a small handkerchief of grass by the turning circle. That's the hold.
I suspect it was approved, despite its proximity to the runway because of the displaced threshold... all the same it is very close.
This background out of the way, I enjoyed my first visit the other day in a reasonably large twin. On departure, we were surprised to find that having back-tracked the runway towards Charlie, on turnaround, we were nose-to-nose with a small Piper (based at the local school), that had followed us unannounced, up the runway, and could now only vacate to Charlie with great difficulty. In the event, we started our take-off roll wing-tip to wing-tip with the Piper still effectively sitting on the runway.
Is this standard practice at Welshpool, or just a one-off? This was not just some low-hours student, there was an instructor in the aircraft. I would have been more comfortable if he'd either announced his intentions on the radio, or not bothered back-tracking until we had gone.
