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

This is a US Navy free balloon as used for initial lighter-than-air training during the 1920s to 1940s. It is fairly representative for a type of aircraft that first flew in 1783 and soon afterwards found a shape and construction that it retained (almost) to this day.

Handling instructions

The ZF Navy free balloon with the envelope shader enabled.

Important controls / keys

Flight controls

  • Gas valve
  • Ballast

Ballast

  • W - Weigh-off to 10% of current weight by dropping ballast. Takes about 10 seconds and only works when on the ground.
  • w - Show current on-ground weight. Only works when on the ground.
  • D/d - Drop ballast in 1%/0.1% decrements.

Gas

  • F/f - Open/close the gas valve.
  • R - Rip the envelope. Use only close to the ground and when you really really want to stay there.

Dependencies

This aircraft depends on instruments from some other aircraft (for FlightGear 2.6.0 and above). Install these too.

Known problems

  • The balloon envelope shader doesn't show over MP unless the property /sim/rendering/shaders/aircraft/balloon-envelope/quality-level is manually set to 1. The property might no longer be visible in the shader settings dialog also when the ZF Navy free balloon is the user's aircraft.
