Vne And Density/pressure Alt?

[Guest sharky]

Why does VNE decrease with an increase in DA/PA?

[Winnie]

Because the density of the air is less. If you were able to use a TAS indicator you'd see that the TAS remains the same while the IAS becomes less with an increase in Density Altitude.

 

The reason is that since the air is less dense, there is less "felt pressure" in the ASI, thus it would indicate less at higher altitudes.

Hope that helps somewhat.

Great winn, thanks

Great Avatar, just like I feel almost every morning when I get to work, firing up the machine (computer that is)

Winnie,

 

That was a very simple and clean explanation of the phenomenon.

 

Well done! :up:

[Winnie]

THANX!!

If I could only explain all the rest as easily!!

:shock: :shock: :up:
