- METAR changes caused strong aircraft movements if the station temperature or field elevation changed. Temperature and dewpoint are now also slowly interpolated to reach the new value.
- Probably unnoticed bug: calculation of the interpolation speed was wrong.
- some minor code-cleanup
Patrice Poly:
After investigation, it appears that the probes are reversed due to a
little mistake when someone changed how the probe calculations are made.
probe 0 is under the plane. probe 4 should be downwind, probes 1,2 and 3 should be upwind.
Improvements to the cloudsystem:
- A new xml format
- Texture indexing based on the position of the sprite in the cloud
mass, allowing more control over the texture set.
- Improved fog and shading
- Better sprite distribution
- A more natural distribution of clouds, so no more obvious grids.
While troubleshooting the new environment I discovered the metar station
elevation (station_elevation_ft) is never being set because there is a
local variable that overrides it.
8:: AWOS is available at AWOS locations. (Previously only ATIS was
implemented.)
9:: ATIS phraseology now more nearly conforms to international
standard METAR pattern, and therefore to usual FAA practice.(*)
Items marked with a (*) are fully implemented in the /text/ of the
ATIS message, but the voiced version of the message is degraded by
limitations of the FGFS built-in text-to-speech system.
10:: ATIS now reports sky condition.(*)
11:: ATIS now reports multiple layers of clouds, not just the lowest
layer.(*)
12:: ATIS now takes field elevation into account when calculating
sky condition and ceiling.
13:: ATIS now reports dewpoint.(*)
14:: ATIS now can handle negative quantities (temperature and dewpoint).(*)
15:: ATIS can now report report fractional-mile visibility.(*)
16:: ATIS now uses magnetic (not true) wind directions, as it should.
17:: ATIS generates correct runway number and suffix (nine right,
one one left).
18:: ATIS can be received on nav frequencies, not just comm.
19:: Nothing bad happens if the same ATIS is tuned up on more than
one receiver.
20:: ATIS can be updated at times other than at the top of the hour.
21:: ATIS listens for an "attention" signal, and responds to changes
in the weather by issuing a new ATIS message (somewhat like a
"special observation").
22:: ATIS volume now responds to radio volume setting.
23:: Area-related services (i.e. approach radar) are handled
more-nearly consistently with radio-frequency related services.
24:: ATIS sequence-letter generation has been fixed.
25:: ATIS messages are now in the property tree, so they can be read
e.g. via the http interface.

/environment/metar/xxx properties filled before nasal-dir is initialized.
The quotes form is normally only used for headers with path relative
to the including file's path, though the standard doesn't strictly
mandate this. This is consistent with the rest of sg/fg, it makes the
code's intent clearer and helps to find headers. (And it's a few
milliseconds faster, too.)
