g. Approach (APR) Mode
The APR mode is intended to capture and track the lateral and
vertical guidance for instrument approaches while transitioning
from HDG, ROLL, or NAV mode. GPS to ILS transition is
supported while in GPS NAV mode. (See NAV radio pilot guide
for specific information.)
NOTE: The autopilot will be driven by roll steering input in
the APR mode prior to transition to an ILS navigation
source.
When the pilot selects APR mode by pressing
the APR button, the autopilot engages either
APR Arm or APR Capture mode, depending
on course proximity and closure rate. Roll or
Heading mode can be active with APR armed,
but these lateral modes disengage as soon
as the APR capture sequence begins.
Once the APR lateral course is captured, the system
automatically determines whether a vertical guidance source,
such as a glideslope, is available. If so, the system enters either
a GS Capture or GS Arm mode. Once the vertical guidance
source is captured, the autopilot deactivates any other vertical
guidance mode and commands pitch attitudes necessary to
track the vertical guidance.
The text inside the button depicts the APR
source and the type of source (VOR, LOC,
LOC BC, GPS) and a vertical guidance source
(+GP, +GS), if applicable. Active radio-based
navigation sources display green. Active GPS-
based navigation sources display magenta.
NOTE: When equipped with a digital HSI, any course intercepts
requiring a turn greater than 105° will automatically
activate the localizer back course.
