RADIO NAV page
RADIO NAV page is used to monitor and control the navigaion radios. It is displayed by pressing RAD NAV key.
The FMS automatically tunes NAV1 and NAV2 radios to the closest stations. Also, when approaching destination airport and
ILS approach is selected, the ILS frequency is automatically tuned. You can manually set any radio frequency, which overrides
the autotuning.

VOR1/FREQ: Station ID and frequency of NAV1 radio. Autotuned frequencies are shown in small font. You can enter
new frequency or station ID, which will be displayed in lagre font. This overrides the autotuning. To resume autotuning,
clear the eld using CLR key.
CRS: VOR1 course can be entered here. If an entry is made, the VOR1 autotuning stops.
ILS/FREQ: ID and frequency of ILS. When an ILS is automatically tuned for approach, the data is displayed in small
font. Manual entry is possible and is displayed in large font. Manual entry can be cleared. Until ILS is automatically or
manually tuned, the eld shows “--NAV--”. This is because Flight Simulator has only one radio for both NAV1 and ILS, and
this radio is used as NAV unless ILS is needed.
ADF1/FREQ: Frequency of ADF radio. New frequency can be entered in this eld.
VOR2/FREQ: Station ID and frequency of NAV2 radio. Autotuned frequencies are shown in small font. You can enter
new frequency or station ID, which will be displayed in lagre font. This overrides the autotuning. To resume autotuning,
clear the eld using CLR key.
CRS: VOR2 course can be entered here. If an entry is made, the VOR2 autotuning stops.

REV 01 SEQ 001 Backup instruments
DDRMI
The Digital Distance and Radio Magnetic Indicator displays DME distances and bearings to the tuned VOR stations. Bearing
pointers are overlaid on magnetic heading compass rose.
VOR1 needle is single dashed, and VOR2 needle is double solid.
Standby instruments
Standby instruments serve as a backup to provide vital air data in case of electronic instrument sytstem failure. The instruments
include analog airspeed indicator, single-needle altitude indicator with numeric readout, and attitude indicator.

REV 01 SEQ 001 Landing gear
Gear panel
Gear controls and indicators include gear lever, gear indicator lights, autobrake system
controls, and brake pressure indicator.
Gear lever can be controlled with the mouse, or using standard Flight Simulator keys.
Three indicator lights show status of left, nose and right gear. Green triangle indicates gear
down and locked, red “UNLK” is shown when gear unlocked (in transit). No indication means
gear up and locked, and bay doors closed.
Autobrake system provides automatic braking, and has 3 modes, “LO”, “MED” and “MAX”.
Modes are armed and disarmed by pushing corresponding button. LO and MED modes are
used for landings. At touchdown, if one of these modes is armed (blue “ON” is visible),
the anti-skid brakes will be automatically applied. LO and MED modes provide different
deceleration rates. When autobraking is in process, a green “DECEL” is illuminated on
selected button.
MAX autobrake mode is used for takeoffs. In case of rejected takeoff, with MAX autobrake
armed, speed above 80 knots and throttles retarded to IDLE or MREV, the system will
automatically apply maximum braking.
BRAKES indicator gauge shows hydraulic brake accumulator pressure and pressure applied
to left and right main wheel brakes.
