Toppled Gyro
The various states of ICAO can vary certain rules to suit local influences.................here in Australia the 60 old year rule was challenged and discarded years ago....hence old fella's like Nigel are still seen in the sky today.
We have a number of active COMMAND pilots in their late 60's...including a very healthy Government Inspector.
There are a few requirements when these Captains are flying Charter type operations.....their first Officer must be below 60 years old, and of course there is more demanding Class One medicals.......
But apart from that, you can fly until you want to retire.
