ATPL EASA Radio Navigation Practice Exam - Practice Test & Study Guide

The component typically not associated with Very High Frequency (VHF) is the Non-Directional Beacon (NDB). NDBs operate in the Low Frequency (LF) and Medium Frequency (MF) bands, generally below 300 kHz, which is well outside the VHF range.

In contrast, other components like VHF Direction Finding (VDF) systems and Markers, such as those used in ILS approaches, operate within the VHF band, typically ranging from 30 MHz to 300 MHz. The Instrument Landing System (ILS) uses VHF for the Localizer and the Glide Slope, ensuring guidance for aircraft during landing phases. Therefore, NDB, being in a different frequency category, is not considered a VHF system, cementing its status as the correct choice in this context.
