What is the maximum bearing error permitted for a VOR equipment check using an FAA-approved ground test signal?

The maximum bearing error permitted for a VOR (VHF Omnidirectional Range) equipment check using an FAA-approved ground test signal is 4 degrees. This standard is crucial in aviation because VOR is a vital navigational aid for aircraft, allowing pilots to determine their position relative to the station.

Maintaining a maximum bearing error of 4 degrees ensures that pilots receive accurate navigational information, which is essential for safe flight operations. A tighter limit on bearing error helps minimize the risk of navigational mistakes that could arise from inaccuracies. This stringent requirement reflects the FAA's commitment to safety and precision in aviation operations.

Knowing this standard not only aids pilots during pre-flight checks but is also part of the larger framework of aviation regulations and operational standards that enhance flight safety.
