SECTION 3
EMERGENCY PROCEDURES
There is no change to the airplane emergency procedures when this
instrument is installed.
SECTION 4
NORMAL PROCEDURES
Normal procedures for operation of this system differ little from those
required for the more conventional Course Deviation Indicators. However,
several small differences are worth noting.
The rectilinear movement of the omni deviation bar in combination
with the rotation of the compass card in response to heading changes,
provides an intuitive picture of the navigation situation at a glance when
tuned to an omni station. When tuned to a localizer frequency, the omni
bearing pointer must be set to the inbound front course for both front and
back-course approaches to retain this pictorial presentation.
When the HSI system is installed with a Cessna 400A (Type AF-530A)
Autopilot or Cessna 400B (Type IF-550A) Autopilot, a back-course indica-
tor light labeled BC, is mounted adjacent to the HSI and will illuminate
amber when the reverse sense (REV SNS) switch (mounted in upper
portion of the pilot's instrument panel on 337 Models or is mounted in the
autopilot accessory unit on 210 Models) is placed in the ON (LOC 1)
position to alert the pilot that back-course operation is selected. The BC
light is incorporated in the MODE SELECTOR on 400A and 400B IFC
systems. The HSI needle will not be reversed but the LOC signals to the
autopilot will be
7
Light dimming for both types of BC lighting is provided
for low ambient light conditions.
For normal procedures with autopilots, refer to the 400A, 400B, 400A
IFCS and 400B IFCS Autopilot Supplements in this handbook if they are
listed in this section as options. A description of course datum and
autopilot procedures for course datum are incorporated in the appropriate
autopilot supplements.
