Approach - Century 2000 Pilots Operating Manual

APPROACH - The APR mode provides an
automatic 45 degree VOR-LOC intercept angle
and selected angle intercepts when the system
is equipped with an NSD-360A, NSD-1000 or
other HSI.
The intercept, crosswind, and tracking sequences are similar to those
described in the NAV mode of operation except that 70 seconds after the
on-course turn the bank angles are reduced to 12 degrees. *The APR
mode has additional enabling logic for the automatic glideslope arm,
capture, and track sequence and must be used on ILS approaches.
REVERSE (Back Course) - The REV mode is for
use in tracking the localizer back course
Inbound and front course Outbound or VOR
course Outbound.
Automatic 45 degree intercepts, selected angle intercepts, crosswind
correction and tracking are as described in the APR mode except that
response to radio signals is reversed.

When using an NSD-360A, NSD-1000 or other HSI always set the radio
course pointer to the inbound front course localizer heading.
When using a DG, always set the heading bug to the final approach
heading to the airport.
*PITCH OPERATING MODES
*ALTITUDE - ALT mode will cause the aircraft to
maintain the pressure altitude present at the
time of ALT engagement.
*ALT may be engaged at maximum rate of climb or descent, but for
passenger comfort, rate of climb or descent should be reduced to 1,000
feet per minute or less prior to ALT engagement. Depressing either the
pitch UP or DN switch will shift the AP mode back to ATT mode.
*ATTITUDE - ATT mode places pitch command with the pitch UP and DN
switches. Pitch is always synchronized to the existing aircraft attitude
after pitch modification.
transferring the system to ATT from ALT, the aircraft will maintain its
existing attitude.
*PITCH MODIFIER SWITCHES - The pitch
modifier switches are momentary push-button
type, located on the right side of the Mode
Programmer, used to modify the airplane's
attitude and to shift the AP from the ALT mode
to the ATT mode.
*GLIDESLOPE COUPLING - In the presence of selected APR mode only
and other enabling logic, the glideslope function is fully automatic.
Therefore, no GS engage switch is used.
