Which method indicates the VOR station selected is correct and serviceable?

Receiving the station's Morse code identifier is a reliable method to confirm that the VOR (VHF Omnidirectional Range) station selected is correct and serviceable. Each VOR station transmits a unique Morse code identifier which can be heard by the pilot through the receiver in the aircraft. When the Morse code is received clearly and without distortion, it indicates that the VOR station is operational and that the aircraft is tuned to the correct frequency.

This method is particularly important because it not only verifies the station's identity but also confirms that the station is transmitting adequately, which is essential for accurate navigation. Pilots typically use this auditory cue as a part of their pre-navigation checks to ensure they are receiving the proper guidance from the selected VOR.

Visual confirmation of navigation charts, listening for a continuous audio signal, and checking the aircraft's GPS can provide useful information, but they do not serve as definitive indicators of the VOR station's operational status. Visual confirmation can be subjective, and while a continuous audio signal may suggest the station is active, it does not confirm that the selected frequency corresponds to the intended VOR station. Similarly, GPS confirmation may reflect location but does not always guarantee the associated VOR station's serviceability. Thus, the Morse
