5 Analog Vario
The resolution of analogue vario is 40 fpm or 0.2 m/s.
The first full-scale range is from +/- 0 to 800 fpm (+/-4 m/s) after which the display switches
automatically to a second range from 800 to 2000 fpm (4 to 10 m/s).
The time interval (damping) over which the measured climb rates are averaged for the
analogue (and associated sounds) is factory set at 1.2 seconds. This can be changed to any
value between 0.6 sec and 4 sec. in Menu/Basic Settings/Vario-Speed-Average. If the time
interval is too short, the vario is very twitchy; if too long, it’s rather sluggish. A lower
dampening value is preferable for smooth light conditions. A greater dampening value may
be desirable in rough turbulent conditions. Note: This setting should not be confused with
vario integration (averager) that can be set for the digital vario display.
A small pre filter can be adjusted to be used as a turbulence filter. It can be adjusted from
0.1s to 1 s. (Settings 1 to 10)
5.1 Altimeter and Air Pressure
The Flytec 5020 has 3 altitude displays.
Alt1
is always the altitude above sea level (QNH).
Alt2
is a reference height; it can be altered or zeroed at any time
Press F1 several times until „Mod A2“ appears. The arrow keys change A2.
F2 resets A2 to zero.
Alt3
cumulates the gained height over one flight
Among the user selectable fields there is another altimeter called “Flight-Level” FL (ft) ; It
cannot be adjusted by the user and is based on an air pressure of 1013 hPa at mean sea
level.
Altimeter Alt1 should be adjusted to display the correct height above sea level. It is originally
set by the manufacturer to a sea level pressure of 1013hPa. Since this is seldom the case,
the correct altitude should be set before commencing each flight by using the arrow keys,
increases altitude, decreases altitude. he Info line is telling Mod Alt1 . By means of
this adjustment the air pressure display changes too. This air pressure (QNH) always refers
to sea level.
During flight recording Alt1 adjusting is blocked.
The user can obtain the altitude of a location even if this is unknown by setting the sea level
air pressure (QNH) (rec. from the radio) in the set up menu. Or he/she can press the F2
key. If the unit receives satellites the GPS altitude is taken over to Alt1. If there is no Satellite
reception the 1013 hPa altitude will be used. (Same as FL (ft))
A2, A3, FL (ft) and QNH can be displayed within the user selectable fields
If Alt1 is set to zero for any planned landing area, then the height above this location will
always be indicated after starting. The associated air pressure (QFE) is the actual air
pressure in hPa at this spot, which deviates from QNH, the pressure at sea level, according
to the difference in altitude.
5.2 Acoustics and Volume Level
In the acoustic menu, most of the parameters can be set to fulfill most of the pilots wishes.
Each time the key /Route is pressed briefly, the volume level is increased by 25%. The
adjustable sound levels are: 0- 25% - 50% - 75% - 100% - 0. The value of the chosen
volume level is displayed on the status line.
