4.3 SELECTED COURSE FAILURE
If selected course is not received by the EHSI, the selected course
arrow head and tail are removed from the display and the course
deviation scale is fixed in a horizontal position (selected course
defaults to aircraft heading). The to/from arrow will continue to be dis-
played if the to/from signal is still received from the selected naviga-
tion source. The to/from arrow and course deviation may be incorrect
since the selected course used by the navigation source (if any) is
unknown.
4.4 SELECTED HEADING FAILURE
If selected heading is not received by the EHSI, the selected heading
bug is removed from the display.
