R22 Hover Ceiling Graphs
Hi all,
New to Pprune,
First, obligatory apologies for stupid questions. I'm about half way through the PPL training and have been given some nasty homework. I'm far too old for homework but sadly nobody seems to care (especially my instructor).
My question is this ......
All of the performance data on the R22 Beta that I've read tells me that the max Hover IGE ceiling at MAUW is around 9500ft.
How is this figure calculated? The relevant graph in the manual doesn't seem to show this at all.
For that matter, it seems easy enough to calculate max allowable weight given PA and temp info but how does one calculate max hover ceiling given only weight and temperature information?
Do you just work through the graph backwards? If that is the case, how is the above max IGE hover ceiling of 9500ft (at max all up weight) calculated? It doesn't seem to match.
Once again ..... sorry if this makes the pro's groan with frustration.
Many thanks
Norvill.
