AltAIR unit features an independent speed sensor (Pitot tube), a
bluetooth vario with a speaker and 4 key programmable keyboard on the front
panel. This arrangement maybe used independently just by switching on the vario
on the pod keyboard. But that is not it yet! The preinstalled bluetooth vario
also works in combination with Altair App (Android), XCSoar and LK 8000. A few
words about the latter. Altair App is a fully functional competition ready
navigation software which executes pretty much all the tasks a pilot needs
during comps or XC flying. It is VERY flexible allowing total control over the
screens’ setup, font size and colour. It has a great collection of widgets that
can be easily added and set up: baroaltitude, airspaces, offline maps, AGL, wind
direction and the speed, true air speed, gps speed, glide ratio, start
gates/final glide etc. It has very useful function of adding waypoints either
from a wps/gpx file or by just tapping on the map. Altair App produces an IGC
tracklog and is compatible with XContest platform. It also connects to the
keyboard of the pod and lets the pilot pre-program the functions of the keys,
such as move to the next waypont, zoom the map, etc.
