"As a result of this, every 3-4 weeks it is a requirement of most companies I have worked with, that a full power T/O is carried out to ensure full power is available in the event of an emergency."
Is there not a CAA regulation which surrounds this too? I recall a Spotty M Captain telling me... every 28 days or something as a requirement to prove that the engines can still actually "do it" if required.
Anyone know if this is just company or actually regulatory?
