STANDBY FLIGHT INSTRUMENTS (CONT'D)
The standard (STD) pushbutton switches the altimeter display from standard pressure to
barometric (BARO) pressure. The rotary BARO knob allows for barometric altimeter adjustment.
The ILS is a multiple-press pushbutton to select or deselect ILS front-course and localizer
back-course (BCRS).
Annunciation for both ILS and BCRS is presented on the top left corner of the display as a green
ILS or a green B/C.

Standby Magnetic Compass
The standby compass is independent, and does not interface with other systems. It is a
self-contained, dry compass which uses eddy current damping to prevent overshooting. A
miniature aircraft pointer indicates aircraft heading, in relation to magnetic north, on a rotating
vertical compass card.
A compass correction card, mounted above the instrument, is used to record the values that must
be added to or subtracted from the compass indications, in order to correct for the influence of
magnetic materials contained in the aircraft, and magnetic fields from the avionics systems near
the compass.

CLOCK/CHRONOMETER (GPS-SYNCHRONIZED)
Description
A Smiths GPS clock/chronometer, model no. SR261902, is installed on the center of the
instrument panel just below the ISI.
The clock is comprised of an LCD display, divided into three segments:
• The upper segment provides the flight time, in hours and minutes, from 00:00 to 99:59.
• The middle segment provides either Coordinated Universal Time (UTC) (in hours, minutes,
and seconds, from 00:00:00 to 23:59:59), local time (LOC) (in hours, minutes, and
seconds, from 00:00:00 to 23:59:59) or date (in day, month and year).
• The lower segment provides a digital presentation of chronograph time (in minutes and
seconds, from 00:00 to 99:59).
The clock will receive and process an external GPS time source when in GPS mode, provided the
signal is valid. If the GPS signal is not valid, or the clock is placed in MANUAL mode, it will use its
own internal time base.
While in GPS mode, the clock uses the external GPS time to synchronize its internal time base.
Flight Time (FLT/RST)
Flight time (FLT) represents the time that the aircraft is airborne, as determined by the status of
the in−air/on−ground discrete input. The FLT starts counting from zero (00:00) when the
on−ground/in−air input transitions from ground to airborne. The FLT stops counting when the
on−ground/in−air input transitions from airborne to ground.

CLOCK/CHRONOMETER (GPS-SYNCHRONIZED) (CONT'D)
The FLT resets to 00:00 by pressing the FLT RST pushbutton for a period of 2 or more seconds.
Chronograph (CHR)
The chronograph (CHR) begins counting upon depression of the CHR pushbutton. The first press
starts the CHR from zero (00:00). The second press stops the CHR timer. A third press deletes the
display and resets the CHR timer.
GPS/MAN
GPS
The clock uses external GPS time when the user has selected GPS mode. GPS mode is
indicated by an illuminated GPS indication on the LCD display.
MAN
The clock uses its internal time base when the user has selected manual mode. Manual mode
is indicated by the absence of the GPS indication on the LCD display.
MODE
The MODE pushbutton provides two functions:
• UTC/LOC/Date display mode switching; pressing the mode pushbutton will toggle between
the UTC (Coordinated Universal Time), LOC (local time) and date displays.
• UTC/LOC/Date set modes; pressing and holding the mode pushbutton for more than two
seconds, the clock will enter the UTC, LOC and date set mode.
