aeroplanes that is controlled by a single on/off icon on the panel. The XML gauge operates
such that all the control inputs that the pilot would normally make are simulated so that the
landing will happen automatically with no input from you, the pilot, once the icon is clicked.
The gauge operation is controlled by the following parameters in the panel.cfg file for the
plane you are flying:
The XML gauge itself is activated by placing control lines in the panel.cfg for the panel you
are using. The control lines are placed in the [window00] section of the panel.cfg, normally
as the last numbered line with sequential gauge numbers. So if the last line of this section in
your file is, for example;
gauge33=737-400!Autobrake, 581, 134
then add another line, as follows. Cut and paste this line into your panel.cfg, incrementing the
number after ‘gauge’ by 1:
gaugeXX+1=Autoland!Autoland_small, W,X,Y,Z
where W and X are the positional coordinates for the top-left-hand corner of the icon on the
panel, and Y and Z are the size coordinates for the icon itself. I normally position the icon
adjacent to the default icons so that it is easy to find and to locate in the panel.cfg – see the
pictures above.
In this example, they would be;
gauge34=Autoland!Autoland_small, W,X,20,20
as 20 pixels is about the normal size for an icon, but you may need to experiment to find
what’s best for you.
Remember to increment the control line, and change ‘small’ to ‘medium’ or ‘large’
depending on the plane that you are flying. This may all sound a little complicated but is easy
to work through if you are systematic. The final effect is worth it!
The landing parameters set in the gauges are:
Small: approach speed 135 kts, full flaps minus one increment.
Medium: approach speed 125 kts, full flaps.
Large: approach speed 145 kts, full flaps.

These parameters provide a slight nose-up attitude on approach that assists the flare. The
values may be changed manually on the autopilot at any stage of the descent. Also, the
autoland system can be switched off at any time, leaving the controls as set by the system.

GAUGE OPERATION:
Fly the plane normally making a normal descent. If you are flying IFR and wish to use the
autoland feature, it is best to cancel the IFR at about 7-8,000 feet, as the approach instructions
given to you by the FS ATC will not be the same as the approach that the autoland system
will make.
Set the altitude for around 6,000 feet AGL (above ground level), the airspeed to around 200
kts IAS with flaps set accordingly. Set your approach vector to intercept the localizer for the
chosen runway in the normal way, at a distance of about 20-25 miles. Set the ILS frequency
in NAV1 and the airport VOR in NAV2.
Click on the autoland icon, which will glow green. From this point until you taxi off the
runway, the operation is fully hands-off and completely automated. As you make the
approach, the gauge:
- Sets the approach altitude for 3,500 feet AGL. The gauge tracks the plane’s height via
the radar altimeter so that you will always be targeting the set height above ground
level, regardless of the altitude of the airport. This will mean that the plane may rise
and fall as the land rises and falls. This is normal.
- Reduces speed to around 180-5 kts IAS at a distance of >14 miles as measured by the
ILS DME.
- Reduces speed to around 160-5 kts IAS at a distance of <14 miles as measured by the
ILS DME.
o Flaps are lowered by one notch.
- Carries out the following operations when the localizer is captured:
o Activates the ‘approach’ hold on the autopilot.
o Switches on the landing and taxi lights.
- Carries out the following operations when the glideslope is captured:
o Reduces airspeed for approach to 135 +/- 10 kts IAS (gauge-dependent – see
below).
o Applies landing flaps.
o Lowers landing gear.
o Arms the autobrake.
o Sets trim for landing – the plane will flare as it nears the runway.
- At 5-10 feet above the runway:
o Cuts the throttle.
o Switches off autopilot functions.

o Engages wing leveler until touchdown.
- On touchdown:
o Applies reverse thrust.
o Applies autobrakes.
o Deploys the spoilers.
- At 55-60 kts:
o Cuts reverse thrust.
o Releases autobrakes.
o Raises flaps.
o Lowers spoilers.
o Switches off the yaw damper, pitot heat, ice detection and landing lights.
