11.6 Glide computer
This page allows glide computer algorithms to be configured.
Glide terrain : This determines whether the the glide range line is calcu-
lated and drawn on the map area.
Block speed to fly : If enabled, the command speed in cruise is set to the Mac-
Cready speed to fly in no vertical air-mass movement. If
disabled, the command speed in cruise is set to the dolphin
speed to fly, equivalent to the MacCready speed with vertical
air-mass movement.
Terrain file : The name of the file containing digital elevation terrain data.
Auto wind : This allows switching on or off the automatic wind algo-
rithm. When the algorithm is switched off, the pilot is re-
sponsible for setting the wind estimate. Circling mode re-
quires only a GPS source, ZigZag requires an intelligent
vario with airspeed output.
Auto Force Final Glide : This option enables automatic forcing of final glide mode if
the aircraft is above final glide prior to reaching the penul-
timate waypoint. Forcing final glide early can also be per-
formed manually from the task menu.
Nav by baro altitude : When enabled and if connected to a barometric altimeter,
barometric altitude is used for all navigation functions. Oth-
erwise GPS altitude is used.
