I dont get it. The downwind element. I understand landing downwind is a problem due to transition through hover to backward flight to get groundspeed to zero but in a manoeuvre such as this, how is the groundspeed relevant?
If Ziggy entered the manoeuvre at say 70 knots airspeed and that was enough to safely complete, 70 knots IAS upwind is the same as 70 IAS downwind. What difference does the groundspeed make? The rotor system responds only to the airmass it is travelling through. The groundspeed is irrelevant to the actual physics of the manoeuvre.
It seems to me Ziggy's problem was too low, too slow (airspeed), too steep, too mad. RIP.
Can you explain why the rotorsystem responds differently downwind, if the airpeed is the same in any replies? Thanks.
PS. Ive re-read Dennis's post several times but I still dont get it.
