### What are the ANT and ADF modes on an NDB receiver?

I am seeing this in a simulator, so I don't have a manual for it… On the Bendix King KR87 NDB receiver, the leftmost button labelled “ADF” switches an indicator above it from “ANT” to “ADF” When ...

### What am I doing wrong in this RBI exercise?

The GYRO indicates the flight direction of the aircraft. The RBI indicates where the non-directional beacon(a location on ground that’s sending the plane signals) is located.  Top of the RBI is ...

### How do I calculate drift based on NDB readings?

An aircraft is to track from NDB A to NDB B. The RMI of NDB B reads 357 & RMI of NDB A reads 177. The aircraft is: A: Drifted left of track B: Drifted right of track C: On track I think it is 'C' ...

### What is meant by Manual Tuning of ADF/NDB using BFO? [duplicate]

As NDB transmission is either N0NA1A(requires BFO to be turned on for Manual Tuning, Identification and Monitoring) or N0NA2A(BFO turned on only for Manual Tuning). My question is what exactly is ...

### How can I determine the relative bearing to an NDB using the G1000?

For using an NDB, a pilot should know to MH+RB=MH. But I have never seen a relative bearing displayed in the G1000. Could you let me know where to see the relative bearing in the G1000?

### How do I find the magnetic bearing to the station in this question?

In my PPL trial test, I have the following question regarding an NDB: Consult Figure 3, Illustration 6. On a magnetic heading of 160°, the magnetic bearing to the station is: 045° 205° ...
