NDB OverviewADF Receiver:• Located in an airplane or helicopter; consists of a simple frequency selectable receiver, indicator, and rotating antenna•
NDB OverviewAs helicopter approaches NDB, the signal strength increases and the needle indicates the direction of the platform or vessel
NDB Overview• In almost all cases, radiation is omnidirectional• Structures can cause reflections and false readings on cockpit instruments
