SYNOPSIS
G-JEDR was cleared by Air Traffic Control (ATC) to back-track on Runway (RWY) 21 before turning around and lining up for take-off. A runway turn pad is located before the threshold of RWY 21 that facilitates a 180-degree turn by aeroplanes. The aircraft taxied onto the pad and turned right in order to make a left hand 180 degree turn. While doing so at a slow speed the right main wheel went off the pavement into an adjacent gravel strip. There were no injuries to crew or passengers and no apparent damage to the aircraft.
