So at 6,000 the true airspeed is 210% of that indicated.. or did I get that wrong..?
Fellow Rotorheads,

My apologies. I normally put more thought into what I write.

This should leave you in no doubt:

For true airspeed: Add 5% of your indicated airspreed to your indicated airspeed for every 3,000' of DA.

So, 100kts IAS, 3,000'...105kts true. 120kts IAS, 9,000'.... 138kts true.

Hope this clarifies

A couple of others...

If in doubt, chicken out.

You're only gonna crash when you're near the ground.

If you can't hover, don't bother (landings at altitude).

If you think you're trying too hard, you probably are.
