737ng PFD course deviation indicator
How many degrees does each dot represent?
I can not find it in the manuals. Any reference to where it is stated would be much appreciated:8 -snuble |
Hi Snuble,
I am sure they normally indicate 1 degree per dot, and in expanded scale, a half a degree per dot. That's my best recollection. Cheers...FD...:cool: |
VOR :
The scale is the standard four dot scale. One dot equals five degrees of deviation. ILS : - The localizer deviation pointer The scale is a standard four dot scale. One dot equals 1 degree of deviation. A two-dot expanded scale can replace the four-dot scale. For the expanded scale, each dot equals 0.5 degrees of deviation. The white expanded scale goes to amber and flashes when the autopilot sends an ILS deviation warning. - The glideslope deviation pointer and scale show to the right of the attitude display. The scale is a standard four dot scale. One dot equals 0.35 degrees of deviation. There is no expanded scale for glideslope deviation. |
Full ILS - 1 dot = 1 degree
Exp ILS - " = 0.5 degree VOR - " = 5 degrees Nav - " = 2nm |
