HDG Slave

[Pedro Sousa]

Correct me if I am wrong, but I think HDG SLAVE should center HDG bug.

It doesn't.

Same here, it is not working with the conventional flight model either.

Huh?  The HDG/SLAVE button is working exactly as it is supposed to.  The EFM has nothing to do with it.

Please read this post again.

Understood!
Thak you so much.

From the aircraft manual:

 

2.2 Flux detector unit

Each system has one detector located in the wing to avoid magnetic disturbances. The detector unit consists of two coils oriented 90_ apart which sense the horizontal components (Cos and Sin) of the magnetic field. The coil system is kept horizontal by a fluid damped pendulum.

The output representing the direction of the mag- netic field is transferred to the computer where it is compensated for magnetic errors of the detector. The compensated signal slaves the heading in- formation with 1_ per minute and the result is thus magnetic heading. Each computer has a compen- sator card for adjustment of the magnetic error, which is normally set at the aircraft compass swing (maintenance).

The system also contains a quick heading slave function, which by means of a push button, slaves the magnetic heading related to present flux detec- tor readout. There are two HDG SLAVE buttons, one on each side, located underneath the EHSI:s.

Yeah, that's the technical explanation.  The point is the Heading Slave button DOES NOT sync the Autopilot Heading Bug to your current heading.

Flux detector unit - fluxing...
