Being able to quickly find the aircraft carrier becomes pretty important when your fuel is low. If you're like me you'll be all strung out too after some harrowing dogfights.
Use the UFC to cycle the TACAN frequency to the carrier (Station RRG)
Switch to TACAN steering via the MPCD pushbutton 1 to get steering cues.
Carrier Control wil give you a vector to the pre-approach point (PAP) and your distance from it in miles.
Once you have passed or reached the pre-approach point you will be given a final bearing.
