The trouble with you guys , TC and Syd , is that you both come across as being arrogant old farts who who know everything ! I am just trying to redress the balance a little when you come out with statements that come straight from a rule book . As I said earlier , I agree with the sentiment about trying to avoid things such as HV curve but to say " never fly in it " is unrealistic .
Mmmm, another case of not actually reading what someone is posting
I think you'll find my 'statement straight from the book' was;
"Use of Chart:
Caution:
Observe the cross−hatched regions of the Height Velocity Diagram.
These represent airspeed/altitude combinations from which a
successful autorotation landing would be difficult to perform.
Operation within the cross−hatched area is not prohibited, but
should be avoided."
So, where does it say, 'never fly in it'?
I think it is quite clear; old farts like TC and myself are only trying to prevent some rotorheads that are reading these posts, from falling into the traps that others don't recognise as traps.
U-turn of the thread;
I don't see low flying as being in the HV curve and see no problem with his flying.
Ok ..i accept that low flying may be inside the curve !!
TC, H500 & S_P put it well
