Hi fellow wiki editors!

To help newly registered users get more familiar with the wiki (and maybe older users too) there is now a {{Welcome to the wiki}} template. Have a look at it and feel free to add it to new users discussion pages (and perhaps your own).

I have tried to keep the template short, but meaningful. /Johan G

Revision as of 04:18, 23 August 2008

This article is a stub. You can help the wiki by expanding it.

This is a short description of FlightGears default Head-up display (HUD), it can be (de)activated with the h-key. To change the brightness, press H.

There are also two so called 'minimal' HUDs available which are accessible with I, to return to default HUD press i.

Some of the HUDs options can be altered in the menu: View --> Adjust HUD Properties

Features

HUD overview

Aileron

Aileron

Airspeed

Airspeed

Current speed relating to the ambient air in knot/knots (kt/kts) (1 kt = 1.852 km/h).

Altitude

Altitude

Current altitude relating to sea-level in feet (ft) (1 ft = 30.48 cm).

Autopilot

HUD autopilot

If autopilot is activ the direction of the next waypoint is displayed as well as the next two and the last waypoint of the Autopilot > Route manager list.

Autopilot

Elevation

Current altitude above ground in feet. Relating to the location of the aircrafts radio altimeter therefore it's not zero if the aircraft is on the ground.

Elevator

Elevator

G-load

Displays the g-force to the pilot in g - to avoid black-/redout.

The value riding on top of the Airspeed indicator.

Heading

Heading

Direction of the aircraft relating to the geographical North pole in degree (360 degree scale).

Compass

Location

Location

To change the coordinates-system, go to Autopilot --> Set Lat/Lon-format.

Pitch

Like set with [Home] / [End].

It's the left marker of the Elevator indicator.

Pitch ladder

Displays the aircrafts pitch relating to the grounds level/horizontal in degree. It's used as an artificial horizon.

The big ladder like looking indicator at the HUDs centre.
Attitude indicator

Further Information

The basic setup of the above described default HUD is defined at

$FG_ROOT/Huds/Default/default.xml

There is also a 'Runway projection' available which is, because of some issues, disabled by default.

Documentation can be found at

$FG_ROOT/Docs/README.xmlhud

Since FlightGear 0.9.10 there is also a newer and more flexibly HUD-system available. An example can be found at

$FG_ROOT/Huds/default.xml and documentation at
$FG_ROOT/Docs/README.hud.

Also have a look at $FG_ROOT/Huds/README.
