Usually airplanes are parked on proper parking areas with a concrete or asphalt surface - ramps, taxiways, runways etc. The only exception is aircraft that are "stored" in the desert but those are usually there for scrapping anyway. However, SQ is clearly not planning to retire all the aircraft at ASP in the image. At least the 737MAX and the A380 will return to service and even the A320 have a decent chance. So what are the procedures for parking such heavy jets on unpaved ground? You wouldn't want them to sink in like the BA A380 did on that taxiway shoulder.
Can the aircraft taxi their under their own power or is a tow required? Would it ever be permitted to perform regular operations from a runway or taxiway like that, without a dedicated gravel kit?
How is the strength of the ground assessed? How can the airport guarantee this strength, since these "taxiways" are subject to erosion and natural variation of soil strength?
Is there a required 'smoothness'? There seem to be some bushes growing on these "taxiways" and I would expect wind and water to easily create potholes.
On return to service, do the aircraft need a thorough cleaning just in case dirt got into delicate parts, like the gear and engines?
