eh, you Jimmy: "How almost zero airspeed "flare" could increase NR?" You can actually flare from a dive to horizontal, it works.
Crab
..... wrt "he has lowered the lever to reduce tq reaction and lowered the nose to gain speed."
please see my previous post:
"to gain airspeed in a rotating helicopter ideally the cyclic needs to move in the cockpit at (negatively) the same rotational rate, ie constant bearing."
If you just hold it forward in the helicopter cockpit it doesn't give the helicopter horizontal airspeed, just makes 'a funnel', just like Lake Vyrnwy, and this one.
A lowered lever and a constant bearing cyclic position, from that height would get most helicopters to arrest yaw.
Not without a change of trousers though. Still
well done for surviving, that's what counts, too many airmchair '
experts'.
