MAGNETIC COMPASS
Figure 8.25: Magnetic compass
The magnetic compass is located over the radio receivers and annunciators.
With the gyro in mode SLAVE, there is no deviation between the magnetic compass and the HSI.
Yet when the heading is changed suddenly, there will be a small delay until the magnetic compass
shows the correct indication.
