Mikoyan-Gurevich MiG-21bis: Difference between revisions

All navigation display is shown on the compass on the left side of the front panel. The needle with large flags points either directly to the radio station, or to the setting of the internal navigation system.

The internal navigation system uses indicated airspeed, air temperature, and bearing to triangulate your position.

As you fly around, the azimuth and distance should continue to point towards that destination. It may be off due to errors in measuring your airspeed or the outside temperature, or due to compass drift.

While in flight, ensure the RSBN/ARC switch on the left hand side of the cockpit is switched to ARC, and use the ADF panel on the right hand side of the cockpit to select which frequency to use. This panel has channels 1 through 9 available, and is located next to the comm radio which has a large orange knob in the shape of a cross.

To hear the ID of an NDB, switch the RSET/COMP switch located on the comm radio to COMP, and use the volume knob on the comm radio to set the volume.

While in flight, ensure that the NAVIG/PROCEED/LANDING switch on the left side of the gun sight is set to either <code>NAVIG</code> or <code>PROCEED</code>. Set the RSBN/ARC switch on the left cockpit wall to RSBN. Set your VOR channel using the left knob on the VOR radio. If information is received from a ground radio station, the green lights on the radio will illuminate indicating whether bearing (<code>Azimuth</code>) and/or distance (<code>Dist</code>) information is being received. Note that this input overrides and overwrites the internal navigation system. If contact with a VOR is lost, then the internal navigation system will still point towards that VOR, so be sure to check the green lights to make sure you are within range.
