SECTION 3
EMERGENCY PROCEDURES
HSI
(TYPE IG-832C)
There is no change to the airplane emergency procedures when this
instrument is installed.
SECTION4
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
turned to an omni station. When tuned to a localizer frequency, the omni
bearing pointer must be set to the inboard front course for 2.Q!h front and
back-course approaches to retain this pictorial presentation.
When the HSI system is installed with a Cessna 300A (Type AF-395A),
Cessna 400A (Type AF-530A) or Cessna 400B (Type IF-550A) Autopilot, a
back-course indicator light labeled BC, is mounted adjacent to the HSI and
will illuminate amber when the reverse sense (REV SNS) switch (mounted
in the upper portion of the pilot's instrument panel on 337 Models or is
mounted in the autopilot's accessory unit on 210 Models) is placed in the
ON (LOC 1) position to alert the pilot that back-course operation is
selected. The HSI needle will not be reversed but the LOC signals to the
autopilot will be. Light dimming for the BC light is provided for low
ambient light conditions.
For normal procedures with autopilots, refer to the 300A, 400A and
400B Autopilot Supplements in this handbook if they are listed in this
section as options.
