Atr 42 & 72
 

Hi,

I have the Air Tahiti ATR 42 & 72 DVD from Just Planes.

Can someone tell me what the sound I hear when the aircraft is in approach mode and on final.

You can hear it on the You Tube trailer of the DVD at the 4 min 24 mark and a short burst of it at the 5 min 49 mark, not only on final but just as they land as well

I thought it might be a stall warning but after hearing it when landing confused me.

Thanks for any help.

Regards
David
