Joni Posted January 19, 2018 Posted January 19, 2018 As per manual: SEC (Secours): Emergency operation, the INS provides only gyroscopic information (attitude and heading). I put the knob in SEC for quick take off and heading was totally wrong. Isnt this supposed to give heading from the magnetic compass?

Frederf Posted January 20, 2018 Posted January 20, 2018 Alignment shows a random heading until 2m40s mark where it jumps to the right one. There is a 3-position switch marked CAP SEC which seems to be off-?-on. If the "M" position (full forward) is selected the heading instrument reads directly the magnetoflux compass input. In such a state the Cv-Cm selection results in the same heading. This appears to be completely separate from the INS's notion of heading. Setting the INS mode knob to SEC looks likewise independent to the CAP SEC switch. I'm not sure what INS-SEC is for but if you want a backup HARS-type system the CAP-SEC looks to be what you want. I'm also not sure what the middle position of the CAP-SEC switch does. Is it armed to automatically take over? Maybe it's a setting position to allow some kind of input to align or erect attitude or heading. All heading-attitude systems have some kind of calibrate input. If it's not that switch I don't know where it is.
Guest Posted January 20, 2018 Posted January 20, 2018 Genius! That was what I was looking for! Thanks! The middle position is just for the secondary horizon, the M one is what connects the SEC INS. :)
