Back Course Approach Made Easy!

How should the HSI and flight director be set when making a back course approach?

a) HSI should be set to the localizer frequency, and flight director to "BC" mode

b) HSI should be set to the glideslope frequency, and flight director to "NAV" mode

c) HSI should be set to the VOR frequency, and flight director to "HDG" mode

d) HSI should be turned off, and flight director to "ALT" mode

Final answer:

Answer:

In a back course approach, the HSI should be set to the localizer frequency, and the flight director to "BC" mode.

Explanation:

For proper directional guidance on the flight director when making a back course approach, the HSI should be set to the localizer frequency, and the flight director should be set to "BC" mode. This is option (a). It's important to note that the back course mode (BC mode) is used for localizer-based instrument approaches without a corresponding glideslope. The HSI, or Horizontal Situation Indicator, uses the accurate localizer frequency, showing our aircraft's alignment with the minor axis of the runway.

The correct setting for the HSI (Horizontal Situation Indicator) and flight director when making a back course approach is a) HSI should be set to the localizer frequency, and flight director to "BC" mode. The localizer frequency is used for lateral guidance during the back course approach, and setting the flight director to BC mode will provide the necessary guidance cues.
