•
MacCready uses the Polar data and MacCready setting to calculate speed to fly and
climb rate.
•
Vario uses the last four thermals average to compute climb rate and uses this value to
calculate speed to fly.
•
Avg.Speed & Vario uses the average ground speed over the last 5 minutes for
distan ce and Vario statistics for climb rate.
•
Avg.Speed & MC uses the average ground speed over the last 5 minutes for distance
and MacCready.
All four methods of calculating ETA and ETE (Estimate Time of Arrival & Estimate Time
Elapsed) take into account glider altitude, wind and safety (arrival) altitude thus ensuring
that the calculation made is the best possible.
Suggested methods for competition pilots are Avg.Speed & Vario or
Avg.Speed & Mc .
5.1.1.7 Soaring Start*
Soaring start is the time when the glider starts soaring (released from tow, engine switched
off). A soaring start time is needed to start the flight optimization.
5.1.2 Flight Recorder
The main display unit has a built - in flight recorder fully approved by the IGC (a sub -
committee of the FAI) and will produce secure flight records that are acceptable for all FAI
requirements including world records.
Select the recording interval and enter the pilot name.
Pilot weight is important if
ballast is specified in kilograms of water
(see Chapter 5.1.9.5). If the system is used
in two- seat aircraft the name of the co - pilot may also be entered.
SWAP button allows you to quickly change the pilot and co - pilot (e.g. when flyin g in two-
seater competitions).
There is no setup for glider type. Glider type is defined in the Polar and Glider
setup (see Chapter 5.1.12).
There are very few settings for the flight recorder compared to other instruments.
This is because main display unit will record all additional data such as wind,
speed and vertical speed by default.
