10. ermine the NAV warning flag is out of view Flying inbound to a VOR station is accomplished by first rotating the OBS knob to center the deviation indicator and determining the TO FROM meter is in the TO condition The aircraft is then turned to a magnetic heading which is the same as the selected course with proper allowance for wind correction When the aircraft is on course the vertical pointer will be centered If the aircraft moves off course the deviation indicator will move away from the center position and flying in the direction of pointer deflection left or right is required to re intercept the course The procedure for flying outbound from a VOR station is the same as flying inbound except the OBS knob is first rotated to cause a FROM indication to appear with the pointer centered To intercept a selected VOR radial from the station and fly outbound turn the OBS control to set the desired radial under the top indicator index Maneuver the aircraft to fly the selected radial magnetic heading plus 45 intercept angle which will provide a sufficient intercept angle The intercept angle should be reduced as the deviation needle approaches an on course condition center to prevent excessive course bracketing LOCALIZER OPERATION Select the desired localizer frequency and observe that the localizer warning flag is concealed The TO FROM flag is not functional for localizer operation When flying on the front course or outb
