The list of configurable parameters

  • Distance in meters between the Pilot and the Flight Line
  • Area angle in degrees. This determines the height and width of Flight Plane
  • Flight Area width. Space on both sides of the Flight Line; E.g 200m means 100m in front of and 100m behind the Flight Line where the alarm will gradually change accordingly to airplane position in area.
  • Flight line width. Space on both sides of the Flight Line; E.g 30m means 15m in front of and 15m behind the Flight Line where the alarm will be constant tone
  • Flight Area boundary alarm (Out-Of-Area). If enabled this indicates that the airplane leaves the Flight Area vertical boundary on the left or right side. The distance to the boundaries is calculated regarding ‚dist’ and ‚angle’ options. This option has impact on flight scoring
  • Altitude alarm. If the airplane transcends configured altitude the alarm will indicate Out-Of-Area. To disable set hlimit to 0. If set to 1, the maximum altitude is calculated regarding ‚dist’ and ‚angle’ options. User can also set hlimit to the desired altitude in meters (if hlimit>1). In this case the hlimit an altitude relative to ground. This option has impact on flight scoring
  • Set points P1 and P2 manually. The maximum distance between p1 and p2 must not be greater then 200m. The numbers are decimal degrees with 6 digit precision. Note that these values overwrite the coordinates stored in RCFA memory
  • Automatic Flight Area lock (for example during start)
  • Real-time tracking. If enabled, the RCFA will send position data stream to the Receiver. The data are available on the TX pin of the RCFA RX. The data stream can be visualized directly in Google Earth. It is even possible to visualize real-time tracking as an overlay on Google StreetView picture
  • Automatic reference altitude. Minimum number of GPS satellites that must be active to acquire the reference altitude
  • The reference altitude can be set manually for faster system initialization. It can also be more accurate to use with Google Earth and therefore is strongly recommended. Set the altitude value that is visible in Google Earth at the bottom side of the screen marked as ‚elev’ at your airfield
  • GPS sample rate in ‚Reads Per Second’. The value 5 is the most optimal setting for general purposes. Some GPS can not run faster than in 5Hz mode
  • GPS Logger Automatic mode – The Logger will start and stop recording automatically when the aeroplane enters or leaves the Flight Area (Blue Box)
  • GPS Logger Manual mode (free flight) – In this mode user have to start and stop logging by long press button B
  • Set the Logger speed frequency in seconds. It denotes how frequently the logger will write coordinates to SD Card. This can not be more often then gpshz value
  • 4 different modeo of Floor option
  • ‚Low accuracy’ information feature can be used to verify the GPS signal quality after the flight. If the number of active GPS satellites is lower then lowacc, the system will write time and info: „GPS low Acc” on SD Card in rcfa.log file
  • Configurable filtering algorithm for GPS, Altimeter and Variometer
  • Radio module switch. The radio module can be disabled for lower power consumption
  • Altimeter switch. The RFCA uses barometer sensor for highly accurate altitude readings. This option can be override by „floor”
  • Variometer mode. If enabled the RCFA will send altitude changes data stream to the Receiver
  • (Variometer) Minumim vertical speed ratio. Vertical speed lower then hspmin will be regarded as horizontal flight
  • (Variometer) Maximum vertical speed ratio. When the vertical speed is faster than hspmax than the sound in the Receiver will play extreme tone. Lower values of hspmax cause the sound to change more rapidly at low rate of descent or ascend
  • Time zone relative to UTC. Note that the system does not detect summer and winter time
  • Initial sound volume in the Receiver
  • Event log
