WAIT A MINUTE!

The last time WE discussed this I left the thread with a whole different view of VRS, and from what others have written in previous threads it seems to me they have all gone to the previous paradigm of VRS, or some of us are still confused.

CONTRARY to what some have said . . .

Its EASIER to get into VRS . . . . .

WHEN APPLYING LITTLE POWER, the less power you use, your downwash velocity is less and easier to catch up to, the MORE suceptible to VRS you will be, .

WHEN YOU ARE LIGHT IN WEIGHT, the lighter you are, the lower disc loading, the lower downwash velocity, lower ROD required to get into VRS, EASIER to get into VRS.

WHEN AT LOWER DENSITY ALTITUDES, the lower the DA, the lower the downwash velocity, the rotor doesn't have to move as much air to produce the same amount of lift thus less downwash, harder to get into VRS.

VRS depends largely on Disc Loading and Downwash velocity.

I understand you have to catch up with your own downwash (match downwash velocity with ROD) in order to get into VRS,

Let not again get "VRS/Settling With Power" confused with "Settling With Not Enough Power"

I think I'm right aren't I?
