[Flightgear-devel] CVS update for base package

[John C. <j4s...@ro...>]

changed color of target altitude display on autopilot
parameterized VOR instruments
parameterized HSI and updated NDB needle (This will be redesigned to a more 
apropriate one, but now it points accurately at least)
The HSI and VOR instruments now take an option 
(/sim/instrument-options/$inst/has-gs-needle) to determine if
the glidescope is shown. See preferences.xml. The current default
has GS on the HSI.
