Back to basics... PA effect on V1

[shazapis]

Hello,

A quick one - I can't seem to find a definite answer online...
Is V1 dependent on PA?

I would say yes, especially for (unrealistically) high elevation fields, but let me know what you think...

Any input will be very appreciated!

It is not dependant on it; more affected by it. Vgo and Vstop are calculated taking into account Pressure Altitude amongst other things.
