Question

Using an HSI to fly LOC(BC) approach you set the arrow to:

A) The back course bearing
B) The lateral deviation
C) The glide slope indication
D) The front course bearing

Answer 1

When flying a Loc(BC) approach using an HSI, you would set the arrow to indicate the lateral deviation.

Step-by-step explanation:

When flying a Loc(BC) approach using an HSI (Horizontal Situation Indicator), you would set the arrow to indicate the lateral deviation (option B). The HSI is a navigational instrument that combines a heading indicator, course deviation indicator, and a glideslope indicator.

For a Loc(BC) approach, the HSI displays the horizontal guidance for the back course of the localizer signal. The arrow on the HSI indicates how far the aircraft is deviating from the desired track, allowing the pilot to make the necessary corrections to stay on course.

The other options mentioned, such as the back course bearing (A), the glide slope indication (C), and the front course bearing (D), are not relevant to the Loc(BC) approach using an HSI.
