Heading and Vertical Reference System mode CM

[Sarix]

Hello.

As titled - what does mode CM for the Heading and Vertical Reference System do? Is it correct that mode GM is "Gyro-Magnetic" (or its French equivalent) and Sec. is "Secours" (in this context "Backup")?

Thanks!

You're correct about GM and Sec.

CM = "cap magnétique"

"Magnetic heading" in English. So in this mode the gyro isn't used by the magnetic monitoring unit to generate heading information for the various systems.

It's a copy of an F1CZ flight manual. You can find them readily online

All the manuals I found were missing some pages. Is there a complete one?

The manuals I found online seemed to be some kind of online reader pages manually joined-together before the creator hit their limit.. I feel that pain.
