When flying over the sea and using an inland NDB to fix position with a series of position lines, the plotted position in relation to the aircraft's actual position will be:

DME accuracy standard (en-route) is:

The main advantage of continuous wave (CW) radars is:

An aircraft is intending to track from NDB 'A' to NDB 'B' on a track of 050°(T), heading 060°(T). If the RBI shows the relative bearing of 'A' to be 180° and the relative bearing of 'B' to be 330° then the aircraft is:

ILS receivers showing predominant 90 Hz on both localizer and glide slope; runway QDM 264°. Aircraft is:

Two NDBs — 20 NM from coast vs 50 NM inland. Greatest coastal refraction error?

Positions input to FMC using maximum 5 alphanumerics:

4D RNAV adds to 3D capability:

An aircraft on a heading of 235°(M) shows an RMI reading of 090° with respect to an NDB. Any quadrantal error which is affecting the accuracy of this bearing is likely to be:

VORTAC provides:

When a DME is operating in the TRACKING phase, it interrogates at approximately:

Aircraft on radial 270°, heading 090° inbound to VOR, OBS set to 090°. TO/FROM indicator shows:
