1.1.1The difference between theDX 50 FAI and DX 50
The DX 50 FAI is the official FAI logger which is accepted by the IGC (Inernational glidihg commision). All the
inflight functions are the same by both instruments, the only difference is that the DX 50 has no logger menu and all
its functions. Therefor the record flights or DMST flights can’t be documented when you are flying with DX 50.
1.2 Variometer system
The variometer system consits of these functions:
Total energy compensating variometer (TEC variometer)
Netto relativ variometer
Interval integrator
Speed commnad
Tone generator
The interval integrator calculates the average climbing rate with the time constant, which can be defined by user.
For the speed command calculation the polars are available for some of the more common glider types. For calcula-
tion of some other parameters the included PC program “POLAR.EXE” is available. The DX 50 enables you to put
in these values.
The speed command sygnal is opticaly marked as SC on the main display and as an arrow on the LCD indicator
(vario is marked with a circle on the same place). There is a special audio sygnal during the speed command (no
beeb in + and there is a dead area of audio around zero). The dead audio area can be adjusted in DX 50 SETUP
program.
