The simulator can only do so much, and the limited time available needs to be used to tick the box for the regulatory requirements. Realistically it will take around a month of regular flying practice to feel comfortable again. Fortunately we are not going straight back into a busy environment and the ramp up will be gradual, which gives less pressure whilst we get back in practice.
Remember that it’s not just the pilots that have been affected, air traffic controllers, engineers, cabin crew and ground staff who all perform safety critical roles are in the same position.
