Presumably grounded planes still need a degree of certified maintenance to remain airworthy ?
Will tyres start to suffer if left too long and develop flat spots ?
How long can a plane remain grounded before it needs additional checks and maintenance ?
And irrespective of the availability or otherwise of the planes will airline pilots start losing certification due to simply not flying enough hours ? Presumably requiring a degree of refresher training before being allowed to carry passengers again ?
Just been debating, and it seems some people think that in a few weeks they'll be jetting off to wherever, just as normal, why wouldn't they.
Myself I can see airlines simply having to shut up shop. If not down to the economics of keeping a fleet of airplanes safe, then because anyone travelling in future is probably going to need a *lot* of insurance before they are allowed in anywhere.
I am aware a lot of the issues above "go away" if the certifying agencies (FAA, CAA) just "make them". However the 737Max debacle (which is another depressor on airlines) shows that tends not to end too well.
