While pilot proficiency is controlled by individual Civil Aviation Authorities - they change little from country to country.
Pilots are certified to fly certain aircraft types with a log of the number of take-offs and flight time. To achieve necessary "recency" to be placed in the cockpit of a passenger plane pilots must have at least three flights logged in a 90-day period.
This is something increasingly difficult to achieve with so few planes taking off.
The access to certified flight simulators is also a challenge. The $30million + computer simulators tend to be shared by airlines and located at transit hubs. There are currently simulators in Thailand, Dubai, Sydney and at Airbus headquarters in Toulouse.
In this country Air New Zealand operates a Simulator Centre in Auckland for models across the network including A320s and B777-300. So we won't be seeing any ghost flights out of Kiwi Airports any time soon.
The A380, however, is a different case. The few airlines fly routers with the Airbus superjumbo and as many carriers had begun cutting the fuel-intensive craft from their fleet –even before the coronavirus pandemic – the demand for these simulators is a lot lower than other narrow-body plane models.
