Regarding comments about orbiting not being in any ops manual - we have it in ours.
SOPs chapter "Orbits and similar manoeuvres used to correct vertical offsets at low altitude are a threat to flight safety, particularly at night or in conditions of reduced visibility. The preferred method to correct a verical offset is to request additional track miles from ATC or, in Class G airspace, descend in a published holding pattern.
Descending orbits are not permitted below 3,000ft AGL. Above 3,000ft AGL, they should only be contemplated after due consideration is given to surrounding terrain and in flight meteorological conditions. Autopilot and autothrust should be used".
