Final answer:
VORs are positively identified by their coded Morse signal or voice identification, and they are designed to be accurate within ±1 degree.
Step-by-step explanation:
The only positive method of identification for VORs (VHF Omnidirectional Range) is by its coded Morse signal or by the equivalent voice identification. A pilot should always verify the identity of the VOR by listening to the Morse code or voice identifier before relying on the navigation signal. VORs are designed to be accurate within ±1 degree, meaning a VOR signal can have a total accuracy error of up to 2 degrees. To ensure reliability, periodic maintenance checks are performed on VOR equipment.
