2.5.1.1 Source Selection Annunciation
Use the steps below to determine whether or not the integrated source selection annunciation displayed
on the 500W Series unit to be installed is within the acceptable field-of-view (see Figure 2-2):
1. Determine the pilot’s primary view centerline, utilizing the following criteria:
a) For aircraft with a basic “T” instrument configuration with the attitude indicator in the upper
center location, the center of this instrument should be used as the primary view centerline.
b) If the basic “T” is offset away from the radio stack with respect to the control yoke or a non-
standard instrument cluster is present in the aircraft, the center of the control yoke or stick, in
the neutral position may be used as the primary view centerline.
c) If the control yoke/stick is offset from the center of the pilot’s seat, an imaginary line
extended through the center of the pilot’s seat may be used as the primary view centerline.
2. Measure the horizontal distance from the primary view centerline to the left or right edge of the
500W Series, as appropriate.
3. If the 500W Series unit is mounted to the right of the primary instruments, the internal display of
annunciation within the 500W Series unit is considered to be within the acceptable field-of-view
if the following criteria are met:
•
The left edge of the 500W Series unit is within 12.1 inches of the primary view centerline
and;
•
the top edge of the 500W Series unit is no lower than the bottom edge of the primary flight
instruments or the unit is line abreast with the affected CDI.
4. If the 500W Series unit is mounted to the left of the primary instruments, the internal display of
annunciation within the 500W Series unit is considered to be within the acceptable field-of-view
if the following criteria are met:
•
The right edge of the 500W Series unit is within 8.8 inches of the primary view center line
and;
•
the top edge of the 500W Series unit is no lower than the bottom edge of the primary flight
instruments or the unit is line abreast with the affected CDI.
If the internal display of annunciation within the 500W Series unit does not meet the criteria for
acceptable field-of-view as defined above, an external source selection annunciator must be integrated in
the affected CDI/HSI or an additional annunciator which clearly indicates the CDI/HSI source as VLOC
or GPS must be installed within 13.856 inches of the view centerline.
NOTE
The entire annunciator must be within 13.856 inches of the view centerline.
