Scott,

 

Due to the aging of the airspeed indicators, what the numbers will be for your plane will have to be experimentally determined in your plane.

 

For ballpark, try about 75-80 mph for Vy and maybe 60-65 for Vx.  Note that when I got my Coupe, the airspeed indicator was way off and Vs was 65 and all the numbers shifted upward proportionally.

 

With an accurate airspeed indicator, best glide is near 75 mph so that’ll be near the correct value for Vy.

 

As your altitude gets higher, the two numbers converge till they become the same at the ceiling.

 

Please report the results of your flight tests.  Passing around this kind of information helps everyone.

Anyone have a good idea of what Vy and Vx are for a 415E?

 

(My Vs1 and Vcc are 56 and 70 respectivley.)

 

Thanks

 

Scott
