There are five Tui Max’s parked at Juliet 1 at Manchester, (making that intersection unavailable to traffic).
I would imagine that these aircraft can be worked on in the open to prepare them for short-term storage? Would they remove batteries, empty the fuel water drains and drain potable water? I am sure there is more to it than that. Maybe jack them onto blocks to prevent tyre flats?
They can change engines outside, (under a tent), so I would imagine they can work on Avionics and probes?
