NDB for helicopters

Rich T Guest

Can anyone explain to me how to use NDB in a helicopter to navigate.

I tried putting in the Mhz frequnecy in the ADF, turned it on, but couldn't see anything on any of the displays to show me where to go?

You may try putting the frequency in NAV 1 or 2.

Only the Bell 206 Jet ranger has a ADF indicator, the Ryan R22 doesn't. On the Bell, the ADF indicator is located on the lower-center of instrument panel. The effective range of most NDB's is quite short, 15-25 nm for most with some 50 nm. A few to 75 nm. Choose a close one. Smile

I am using the AS 365 Dauphin Fast helicopter. there seems to be only one place where I can enter the frequency.

I did hear the bleeping tone which indicated it had picked up the frequency, but still did not see any indication as to where to go. There is a small electronic display with 4 triangles placed at 90 degrees from each other. I thought this was indicating where to go, but when the right triangle lit up and I turned right, I went around 360 degrees without it changing.

Could it just be the helicoptet I am using?
