the latest release of XC Soar is out, as of today. I've loaded it on

a bit, but in the sim mode on the couch it looks pretty cool!

Hey Gang,

Looking at this as a possible solution for our Grob 103 syndicate.
Seems as though the XC Soar website is temporarily inop, so here's a
question. * How do log files work when running XC Soar on a 310? *I'm
assuming that the logging rate and other parameters are
configurable? * *What have been your experiences using the 310 as an
unapproved logger?

P3 and gang,

I don't have the HP 310, instead a Nokia 500, but using the 5.2.3F-b4
version, which was the latest at the time, I recorded my Gold distance
flight on 5/17. *Looking at that file, it appears to record every 2
seconds. *Looking at the current version, a9, I see that the logging
rate is configurable from 1 to 8 seconds, with different settings being
possible for cruise and circling flight. *Just for info purposes, this
flight of 3 hours 14 minutes took 230k bytes to store, and contained
6358 records.

It's a great program, and I don't know what else one could want. *I'm
curious about the display brightness with the 310, however. *Can anybody
provide any data for that?

Thanks,
Ed

Ed,
I once measured the brightness of the HP310/314 with a very good light
meter (I'm a lighting consultant and have very good light, UV, and
electrical meters) but I can't find where I wrote down the results. I
posted them here on RAS I think. Anyway the HP310 is much brighter
than the Ipaq 3970 I compared it to. I still don't think anyone could
fly in full sun and the terrain turned on and see it as well as they
would like, for that you need one of them big screens like an ultimate
or a clearnav. With white screen it works very nice.

Charging cables, an easy way to get one is to buy an APC UPC10 power
pack. Comes with a charger and cord, adds a couple of hours of flight
time and handy for keeping the iPhone charged up as well.

Here is the power draw information on the HP310/314:

glider battery at full charge delivering 12.5 volts to the car
adapter, screen on 100% bright.

If the IPAQ 310 is fully charged: .27A

If the IPAQ battery is dead, and therefore charging: .47A

This is about the same as the HP 4700.

the lesson: only fly with the IPAQ fully charged!

above measured with FLUKE 111 ampmeter.



My power budget:

Becker AR-4201 VHF Radio
Average load during flight 0.09

Transponder and Encoder 0.30

Borgelt B40 0.24

iPAQ 310 - charged 0.27

Total amps 0.89

With a 12AH battery in good shape I should get 8 to 12 hrs. depending
on temperature and battery condition. Most Transponders and encoders
will draw more power, mine are very efficient (I hope).
