1. A method comprising:
- determining an actual bearing from an aircraft to an automatic direction finder (ADF) station;
moving the aircraft to a plurality of headings;
determining an ADF bearing from the aircraft to the ADF station at each of the plurality of headings to which the aircraft is moved;
calculating an error between the actual bearing and each of the determined ADF bearings; and
generating an error function based at least in part on the calculated errors.

Abstract
A method and system are provided for calibrating on-board aviation equipment. An actual bearing from an aircraft to an automatic direction finder (ADF) station is determined. The aircraft is moved to a plurality of headings. An ADF bearing is determined from the aircraft to the ADF station at each of the plurality of headings. An error between the actual bearing and the ADF bearing at each heading is calculated. Then, an error function as a function of the heading of the aircraft is generated based at least in part on the calculated error.

10. A system for calibrating on-board aviation equipment comprising:
-
an aircraft; and
a computing system on-board the aircraft configured to;
calculate error between an actual bearing from the aircraft to an automatic direction finder (ADF) station and a plurality of ADF bearings from the aircraft to the ADF station, each ADF bearing being associated with a respective one of a plurality of headings of the aircraft; and
generate an ADF error function based at least in part on the calculated error. - View Dependent Claims (11, 12, 13, 14, 15, 16)

17. A system for calibrating an automatic direction finder (ADF) receiver comprising:
-
an aircraft;
an ADF receiver on-board the aircraft to receive a signal transmitted from an ADF station; and
a computing system on-board the aircraft and in operable communication with the ADF receiver, the computing system configured to;
determine an actual bearing from the aircraft to the ADF station;
determine an ADF bearing from the aircraft to the ADF station for each of a plurality of headings of the aircraft using the ADF receiver; and
calculate an error between the actual bearing and the ADF bearing for each of the plurality of headings; and
generate an ADF error function based at least in part on the calculated errors. - View Dependent Claims (18, 19, 20)
