Glide Distance Vixxen?

[jackc]

Wanting to know the approximate glide specs in distance per 1000ft @ optimum glide speed (which I think is 55kn?)

 

Cheers,

Dunno. But Foxbat Australia knows a lot that is not in the POH. Suggest you find out the ratio and best speed with flaps (1/2 and full) and without flaps while you are at it.

I think the best glide speed will be equal to Vy, which (without flaps) will be faster thsn 55 kt.

Flaps will never increase your gliding distance. Wind and aircraft weight will affect your best glide speed. IF you are gliding into wind you need a faster speed to maximise the distance. you can go. Nev

You could gather your own data on a light wind day using GPS, best glide is 59kn. I will guess 2nm per 1000'. It will be a bit steeper with the prop stopped compared to idle.

Here is a calculator. You can put your own specs in.

Foxbat has 11-1 at 60 kts from memory, so the Vixen should be slightly better...

Thanks everyone for replies, got this info back from Foxbat

 

The A32 has a very high L/D glide ratio at 12 to 1(!) The A22LS Foxbat achieve 9 to 1. Numbers are achieved at MTOW, at best glide speed.

 

A22LS Foxbat/Kelpie - 9 to 1 - For every 1,000ft you go down, you travel 1.48 miles forward at MTOW @ Vg.

 

A32 Vixxen - 12 to 1 - For every 1,000ft you go down, you travel 1.97 miles forward at MTOW @ Vg.

 

Cheers,

 

Jack.

Pretty impressive. The difference between the Foxbat and A32 is huge and shows what can be achieved cleaning up. They are the same wing I think.

That's the main reason for all the streamlining I did on my Jodel. It used to be less than 1:7 but is now around 1:10 at 55kt. That little extra glide distance will be welcome if the noise stops.

Any drag reduction helps you all the time (except when you are to high on approach.). Nev
