[DELETE]Automatic Direction Finder (ADF)

NDB systems are flight checked to an accuracy of at least _____ for an approach.

NDB systems are flight checked to an accuracy of at least _____ for enroute operations.

An aircraft is cruising at 3,000 feet indicated altitude, and is approaching a ridge which is 2,500 feet AMSL. The altimeter setting for a nearby airport at 1,500 feet is 29.82 inches Hg. The OAT at 3,000 feet is -25°C. What is the actual ground clearance of the aircraft over the ridge, assume calibrated altitude is equal to indicated altitude?

_____ is the angular difference between the aircraft heading and the direction to the station, measured clockwise from the nose of the aircraft.

_____ is the angle formed by the intersection of a line drawn from the aircraft to the radio station and a line drawn from the aircraft to magnetic north.

Since the _____ receiver does not have a system failure or “OFF” warning flag, the morse code identifier must be monitored anytime it is used as a sole means of en route navigation.

_____ is a navigational procedure in which the pilot flies to a station by maintaining a relative bearing of 0°.

When _____ the aircraft flies a curved path to the station.
