Heading reference switch

Following my recent ventures to polar regions ( ... php?t=6516 )
I was wondering if the optional aft overhead switch which allows to select NORM (mag) or TRUE heading could be (or is already) implemented on the SimA 738 ?

cf Bulfer book bottom p18 .

Hi Jack
only via the server in my opinion, where is this switch in the real cockpit?

Aft Overhead according to Bulfer (737NG companion book)
I'll "scan " the server to see if that function is assignable.

Would be handy up north as even some navaids are in "true" mode

In the SYSBoard Controller there is a function "HDG REF TRUE"
This will remove the MagVar and display the ND in True Headings.

(The Option on the Server selects if the ND should display in HDG or TRK or a combination depending on the MCP Lateral Mode.)
