Boeing 737 ISFD
 

I'm working on simulation of the ISFD fitted to the Boeing 737.

Could someone tell me what the colour of the ILS diamonds are on the ISFD display please? - probably green but might be magenta. I could only find a BW drawing of it in the online manuals and the one clear photo I found didn't show the diamonds though the scales were visible.

Also are the diamonds drawn behind or in front of the ILS scale markers?

Thank you in advance.

Diamonds are magenta and are behind the scale.

Thank you PH.

I guessed wrong!

The diamonds are empty & white framed when in the armed mode and filled magenta with white outline when in the captured mode.

OK that's another subtlety that is useful to know.

Thanks.

May I assume "captured" mode is valid signal but at >2.5 dots deflection and "armed" is <2.5 dots deflection? I haven't come across those terms but I have worked on one display that had that kind of moding.

T'other way round.

Doh!

Thanks for the correction.
