altitude is, the lower descent rate will trigger this alarm.
“PULL UP”: Excessive sink rate near ground, requires immediate action.
“TERRAIN TERRAIN”: Excessive terrain closure rate.
“DON’T SINK”: Alerts to an inadvertent descent into terrain after takeoff. The alert is given after signicant altitude loss, which
allows for small sinking due to ap retraction etc.
“TOO LOW, TERRAIN”: Insufciant terrain clearance while not in landing conguration. The warning envelope depends on
airspeed and radio height.
“TOO LOW, GEAR”: Too close to ground, at small airspeed and gear are not down. Can be inhibited.
“TOO LOW, FLAPS”: Too close to ground, at small airspeed, gear down and aps are not in landing position. Can be inhibited.
“GLIDESLOPE”: Descending below glideslope. Active when ILS is available and gear down. The warning envelope contains two
boundaries: “soft” warning and “hard” warning. Both boundaries are a function of glideslope deviation and radio altitdue. When
aircraft penetrates the “soft” alerting region, the pilot is given a “calm” warning; if the airplane subsequently enters the “hard” region,
the warning becomes loud. The lower your altitude and the closer you are to glideslope transmitter, the higher is the amount of
glideslope deviation required to trigger the warning.

NO LIGHT: ON, the GPWS system works and generates all warnings.
OFF: GPWS is disabled. No warnings will be generated.
‚ G/S MODE
NO LIGHT: ON, the GPWS system generates Glideslope warnings.
OFF: Glideslope GPWS warnings are disabled.
ƒ FLAP MODE
NO LIGHT: ON, the GPWS system generates Flaps warnings.
OFF: Flaps GPWS warnings are disabled.
„ LDG FLAP 3
Selects landing ap conguration for “TOO LOW FLAPS” warning processing
NO LIGHT: Landing conguration is CONF FULL.
ON: Landing conguration is CONF 3.
GPWS - G/S button
This button is located on the center panel near the standby instuments (on real aircraft it is located
on the wing of glareshield).
When any GPWS warning is generated, an amber “GPWS” light is illuminated.
When Glideslope warning is active, “G/S” is illuminated. Pushing this button while Glideslope
warning is heard suppresses all glideslope warnings. This permits deliberate descent below
the glideslope in order to utilize the full runway length under certain conditions.

Wing and engine anti-icing is controlled by corresponding button. When a button is switched to ON, the anti-icing is engaged.
Probe and window heating is automatic with button deselected. Pushing the button - “ON” illuminates - manually engages the
heating.
Seat belts signs are switched on and off by the SEAT BELTS switch.
NO SMOKING can be switched on, off, or set to AUTO. In this case NO SMOKING signs are automatically illuminated when
landing gear are not locked up.

REV 01 SEQ 001 Chronometer
The chronometer is located on main panel. It includes an UTC time and date display, a chronometer and an elapsed time counter.
Also, a selector switch is added which controls Flight Simulator simulation rate (time compression).

The central window displays UTC hours and minutes. The seconds indicator divides a minute into four parts. No marks are
displayed from 0-14 seconds, one mark is displayed from 15-29 seconds, two marks are displayed from 30-44 seconds, and
three marks are displayed from 45-59 seconds. A push of DATE button toggles the display between UTC and Date, showing
month and day.
The chronometer has a digital minutes window and an analog seconds hand. The chronometer is controlled by CHR button:
