Field ID Description
Max.Climb Once a ight has started, it shows the maximum rate of climb
encountered during the ight. This value uses the integrated vario
not the instantaneous rate of climb. This provides good indication
of the quality of the day's thermals. This value is reset when the
instrument is switched o.
Max.Sink Once a ight has started shows the maximum sink encountered
during the ight. Note that these values are using the integrated
vario. When the instrument is switched o this value is reset back
to zero.
Max.Speed Maximum Speed (returned by GPS) reached during the ight.
When the instrument is switched o this value is reset back to
zero.
McRdyNxtThrm Next thermal expected average speed calculated based on the Mc-
Cready Theory. Considering the dened polar it calculates the
speed next thermal should have if you are ying at a certain mea-
sured True Air Speed (TAS Probe needed). This value is related
with the Speed to Fly and is shown graphically in the Double Bar
Vario.
MotorTemp Motor Temperature (available when connected with Flymaster
M1).
OptGndSpdCone The Ground Speed that you should y in order to minimize the
time to reach the Conical End of Speed Section. This value is
calculated adding the Wind over the current course to the Optimal
Speed To Cone.
OptSpdCone The True Air Speed that you should y in order to minimize the
time to reach the Conical End of Speed Section. This value is
calculated based on the Cone ratio and the dened polar.
Page Num. Current layout active page number.
Pulse Current heartbeat in beats per minute, when using the Flymaster
Heart-G sensor.
RPM Motor revolutions per minute (available when connected with Fly-
master M1).
Speed Indicates ground speed. The speed is only available when the GPS
receiver has a valid signal.
Speed Strt Speed to Start. The speed at which the pilot must y in order to
reach the start gate exactly at its opening.
SpeedToFly Optimal Speed to Fly value calculated according the McCready
Theory. The True Air Speed value is calculated based on the
dened polar and the average thermal speed.
TAS True Air Speed. This information is available when the instrument
is used in conjunction with the Flymaster TAS pitot probe.
Therm.Dur. Time pilot has spent in the most recent thermal.
Thermal top The highest point reached during the current thermal.
Thrml.Perfo. Perfomance of the most recent thermal showing average rate of
climb in most recent thermal.
Time Current local Time. This value is automatic revised when the
device gets a valid Gps Signal. (see Note 2)
Trans.G.R. Glide ratio during transition. Average glide ratio during transi-
tions between thermals.
