AP-1 OPERATION WITH SMART COUPLER
Make sure that your GPS receiver is NOT, repeat NOT, in BATTERY SAVER Mode.
Course Mode
Put a course into the GPS receiver.
Enable the NMEA 183 output from the receiver.
Fly the aircraft to place it on course and on the correct heading. Enable the AP-1 in wing-
leveler mode, and use the trim knob to ensure straight-and-level flight.
Move the mode switch to "COURSE" (to the left) and hold for ½ second. Note that the
green LED comes on. If the LED blinks rapidly several times, then goes off, it means that
the Smart Coupler is not receiving valid information from the GPS receiver.
Once the green LED is on and steady, then switch the AP-1 to tracking mode. Relax!
Heading Mode
Make sure that your GPS receiver is receiving and decoding course information, and that
the NMEA output is enabled.
Fly the aircraft on heading for about 30 seconds to allow the GPS receiver to calculate
your ground track. Use the AP-1 in wing-leveler mode and the trim knob as above.
Move the mode switch to "HEADING" (right) for ½ second. Note that the yellow LED
comes on. If the LED blinks rapidly several times, then goes off, it means that the Smart
Coupler is not receiving valid information from the GPS receiver.
Enable the AP-1 in tracking mode when the yellow LED is on and steady.
Minor heading changes can be made by pushing the mode switch left or right
momentarily. The target heading will skew about 1 degree for every push.
