Your ADF gives you a relative bearing of 235 degrees. Your GPS indicates your magnetic bearing to the station is 140 degrees. What is your magnetic heading?

To determine the magnetic heading, you can use the information provided by the ADF and GPS. The ADF gives a relative bearing of 235 degrees, which means that your aircraft is oriented to the station at that angle relative to your current heading. To convert the relative bearing to a magnetic heading, you need to account for your current magnetic heading.

Given that relative bearing is always measured clockwise from your aircraft's current heading, you add the relative bearing to your current magnetic heading. Since your GPS indicates that the magnetic bearing to the station is 140 degrees, you can deduce your magnetic heading using the following relationship:

1. Calculate the difference between the relative bearing and the magnetic bearing. In this case, the relative bearing (235 degrees) is expressed relative to the aircraft's heading, and we want to find out what heading will position the aircraft correctly towards a magnetic bearing of 140 degrees.

2. The magnetic heading will be the magnetic bearing to the station subtracted from the relative bearing provided by the ADF:

   [ Magnetic\ Heading = Relative\ Bearing + Magnetic\ Bearing ] [ Magnetic\ Heading = 235^{\circ} - 140^{\circ} = 95
