Which device is used to provide navigational guidance information to aircraft in flight?

• A. Navigational Aid (NAVAID)
• B. Night
• C. Lateral Vibration
• D. Mast

Answer: (A)

Navigational guidance information in flight comes from navigational aids, the devices and systems that transmit signals or data to help you determine position and stay on course. These NAVAIDs include ground-based and satellite systems (like VORs, VORTAC, NDBs, DME, GPS) and the cockpit instruments that display their information. They’re specifically designed to provide guidance to the aircraft while you’re airborne, which is why they’re the correct choice. Night is not a device; it’s a condition that affects visibility. Lateral vibration isn’t a navigation device either—it’s not used to provide guidance. A mast is a structural component of the aircraft, not a navigation aid.
