Since conception, the Nimrod OCU L8 sortie was a 3 hour profile
A bit of handling followed by an intermediate landing, QFI departs to the tower, Bloggs 1 assume LHS, 1 circuit and intermediate landng
QFI gets back on, Screen Eng gets off (GASO legality), Bloggs 2 takes LHS, 1 circuit and intermediate landing.
Result - both pilots qualified as P1 - Eng qualified as safe to operate without supervision - with 18 more conversion sorties still to go!
Worked for years, giving confidence to a "young flight-deck" in the early stages - then, after the Toronto crash, they panicked about ar*e covering and wrote it out of the syllabus!
Love many, Trust a few, Why change things that were true ?
