1.3 Digital Vario and Netto Vario
The digital vario has a scale of 10 cm/s (20 ft/m) and a very wide measuring range of +/- 70
m/s. It is therefore also ideal for displaying extreme vertical speeds, such as parachute
jumping.
The digital vario can be set to function as an averager (also called integrated vario), with an
average time delay between 1 and 30 seconds. This is very useful in determining the actual
strength of a rough thermal. The digital vario can also serve as a net or air-mass vario, which
shows the vertical motion of the surrounding air. (Please read section 5.2 Net Vario.)
Additionally, it is possible to set the digital vario to serve as an averager during climbing and
as an air mass vario during gliding. (Set-Mode/Basic Settings/Digital Vario Mode)
1.4 Speed
Airspeed is one of the most significant pieces of information besides vertical speed and
altitude. Increased safety is not the only result of having an exact ASI;( Air Speed Indicator )
it also increases performance during distance flights. The Best Glide, the best McCready
Speed, as well as the Net Vario can function with gliders only when the exact airspeed is
known.
The Flytec 5030 GPS has two independent speed sensor connections.
1. For paragliders the wind wheel sensor is still present. Advantage: it shows the true
air speed and begins to make correct measurements above 1km/h; it is also well-
suited in determining the wind strength at take-off.
Enter Basic Settings/Speedmode ,here it's possible to adjust a lower ( - 10 km/h )
speed range for paragliders ( 20 … 60 km/h.)
2. For hang glider pilots there is a built-in, pitot pressure indicator which is capable of
showing speeds of up to 150 km/h (94 mph); however, it only begins to work
at 30 km/h. If necessary, the pitot tube can be lengthened by a flexible hose to
a turbulence-free spot on the glider.
All “rigid-wing” pilots will appreciate the new analogue speed scale with the precise
distance between stall-speed and actual speed! ( see front picture )
Both speed sensors can be adjusted with a correction factor. The factory adjustment is
always 100% in each case. (Setmode/Basics Settings/ Airspeed correct)
With 2.24 it is possible to set a constant offset onto the pitot tube speed. This Offset in will
be added or subtracted (Depending on the sign) to the actual speed value. This offset is to
compensate for the slower air stream under the airfoil. We recommend to keep the “Airspeed
correct pitot” on 100% if you enter an offset value
The wind wheel sensor measures the true air speed. True air speed = TAS.
The pitot pressure sensor, however, measures the indicated airspeed = IAS
Should you be unfamiliar with the difference in these concepts, please refer to: 5.3 - True
and Indicated Airspeed in the appendix.
Speed readings are in both analogue and digital displays. The user can choose whether
he/she wants to view this as a True or Indicated airspeed in the Set-Up Menu. It does not
matter which sensor is used as internally both speeds (TAS and IAS) are always present.
For pilots, who are flying both, hang glider and paragliders the pitot-speed-sensor can be
switched off in the Setup menu Basic Settings/Airspeed correct, pitot. ( the pitot-sensor
