NOTE: When the Arc HSI is displayed the BRG1 and BRG2 Information Windows and pointers are disabled.

NOTE: If the pilot makes a heading change greater than 105˚ with respect to the course, the CDI switches to the opposite side of the deviation scale and displays reverse sensing.

The Arc HSI is a 140˚ expanded section of the compass rose. The Arc contains a Course Pointer arrow, the TO/FROM indicator, a sliding deviation indicator (the TO/FROM and sliding deviation indicators are one and the same), and a deviation scale. Upon station passage, the TO/FROM indicator ﬂips and points to the tail of the aircraft, just like the conventional TO/FROM ﬂag. Depending on the navigation source, the CDI on the Arc HSI can appear in two different ways:

•GPS, OBS, VOR – Arrowhead

•Localizer – Diamond

Tick marks to the left and right of the lubber line denote half-standard and standard turn rates. A magenta turn rate trend vector shows the current turn rate. The
