And I would really like to know how long it would take a student of yours to reach a solo standard. All those unforeseeable events.
When I did my training, we were taught the basics of flying, plus how to do touchdown autos, hydraulics-off run-on landings, and manual fuel ops (for when the auto governor gave up), as these were the foreseeable and statistically most likely things to go wrong with a Huey. And with 11 hours of dual, all my course went solo.
Further training then covered the less-likely failure modes, up until graduation with 120 hrs and qualified on turbines, general flying, low level, instrument rating, night VFR rating, formation endorsement, sling loads and hoist ops. And since then I have not had a single serious failure. All that has been thrown at me was a high-side N2 runaway in a BK117.
