Flymaster B1 Nav settings

I thought I’d share the User Defined Fields (UDFs) that I use for XC and comp flying. As you probably know there are two pages of UDFs – too bad I’ve got four sets! So there’s a certain amount of reprogramming before and after a comp…

XC and general flying:

1. FL 3. Cur GR 5. Dist Thermal
2. Max Altitude 4. GR Toff 6. Ave Speed

XC flying to goal:

FL Cur GR Dist Thermal
Max Altitude GR Goal Arrival Goal

COMP – pre-start and early part of task:

Dist Edge Cur GR GR Next
Max Altitude Speed Start Arrival Next

COMP – when considering final glide:

Dist Edge Cur GR Dist Thermal
Max Altitude GR Goal Arrival Goal

“Altitude2” – I’ve set this to show Flight Level height (see “Set Altimeter” below) (Edit 25/06/2012 – at some point a new UDF, FL (Flight Level), was introduced, which negates the use of Altitude2. Using FL is much simpler!)

“Dist Edge” gives you the distance to the edge or the cylinder, rather than the distance to the centre of the turnpoint.

“Speed Start” tells you the speed you need to fly at in order to cross the start cylinder at exactly the right time. Once it gets above your trim speed you can head for the start!

“Arrival Goal” estimates the height you’ll arrive over the goalfield based on your current glide ratio. Not to be confused with “A OverGoal” which tells you your current height above the goalfield.

“GR Next” – during a recent into wind task at the British Champs in Pedro Bernardo having this on my screen would have been very useful.

“Arrival Next” – ditto, would be nice to know how much height I’ll arrive with at the next turnpoint.

“Potential Spd” – When you’re on a leg of a task this UDF calculates your average groundspeed over the last 30 seconds only when you’re pointing within +-8 deg of the next turnpoint. So it’s being calculated even when you’re thermalling, which means you can get an idea of what your groundspeed will be when you finally leave the thermal.

Set Altimiter

  • Set QNH to 101.32 then copy the value of Altimeter to Altimeter2, then Altimeter2 will show you the Flight Level height. Perfect for XC flying. Alt2 never needs changing now
  • Get from GPS: Yes

Vario Acoustics

  • Sink threshold: -1.0 m/s (changed from -2.0 – silence is nice, but not too much!)
  • Climb threshold: 0.1 m/s
  • Sink alarm: 0 m/s (0 = off)
  • Base: 700Hz
  • Increments: 10Hz

Advanced Features

  • Damper: 05 (default 08)
  • Cadence: 0 (default 1) NB. 1 provides more differentiation at lower climb rates (up to 0.7m/s) whereas 0 provides better differentiation at climb rates greater than 3.5m/s. So maybe it depends on the day (or location) as to what’s best.
  • Dynamic freq: On (default)
  • Buzzer: 3 (default)
  • Auto Silent: On (default)
  • Start Speed: 5 (default)

I hope this helps you make a start when setting up your UDFs. I’m not saying this is the perfect combination, but it seems to work for me. Let me know what you use by posting a comment…

Edit 08/02/2012. I’ve changed some of my settings according to Richard Carter’s post on pgforum here. In particular the tip about using Altitude2 for Flight Levels.

  2. Hi Tim, why have you changed the cadence to 0? According to the instructions this looks like the less responsive setting.

    • Hi Ben, good question… Simple answer is because I tried it after reading that that was what Richard Carter had it set to! But having revisited it following your comment I might switch it back to 1 again.

      I agree, setting 1 gives more audio sensitivity at lower climb rates (<1 m/s), but once you get over 2.5m/s there's virtually no difference in the cadence as the climb increases. Maybe in spring when we get strong climbs we should use setting 0, then in summer when it mellows a bit we should switch to setting 1?

  3. If only we could break records by simply changing settings.

  4. Hi Tim, I’ve just read your bits above as I’m setting up my new Flymaster Live. It’s making all kinds of noises when just sat still, in particular a low frequeny, dull, buzz… Any ideas? Is it just bored?

    • Hi Ali, I suspect it thinks the flight has started so you might want to adjust the flight start speed threshold up a bit. I can’t remember offhand which menu it’s in… Maybe try 10km/h…

      Good luck in the expire 🙂 race – when does it start?

  5. What about Airspace?

    • I’ve got the older B1 Nav and the airspace implementation is not really there yet. But you need to download the airspace uploaded tool from the website then download the appropriate airspace file from IIRC. There might be stuff on PGforum re airspace on the Live…

  6. Tim, Thanks for the tips! The buzzing is because I’ve just taken it for a bike ride and left it on. It now thinks I’m in a 0m/s condition and is telling me to “hunt”…… Had a little go at screen design. Still airspace hunting. All seems really easy to use so far. X-Pyr… My supporter has had to drop out and I didn’t find a new one, so I’m out unfortunately. The race starts in 3 weeks.

  7. When I designed and uploaded my own screen… It deleted the 3 factory ones. Great.

  8. No joy with any of that! Spent the evening designing my own instead. I have made 4.. Doubt I’ll need all 16.

  9. Hi Tim . In the vario acoustics should Base not be 700hz? 70 doesn’t seem to be an option. Regards lex
