A tablet computer is the most comprehensive solution for VFR moving
map, but none of the cheap ones are sunlight readable.
There are plenty of videos of the Ipad on the net which show its shiny
screen to be like a mirror - if there is a lot of light about.
To get a tablet which is sunlight readable you have to pay about £2000
for something like this

The extra cost of the special LCD polarising layers is about £200 but
sadly the marketing has been differentiated so that only pricey
vertical-market hardware comes with the option.
On my website www.peter2000.co.uk I have a couple of tablet PC
writeups. In 2004 I played around with the IX104 and while it did
everything needed, it was too big and heavy. Then I went to the LS800
and still fly with that - after heavily modding it with a SSD and a
fan araldited on the back (how ridiculous!). When I fly IFR/airways,
it still sits there running but never gets looked at; it runs the VFR
charts for emergency use. I also use it to talk to a Thuraya satellite
phone to get tafs and metars on long flights.
Today, you can buy various Chinese GPSs which run the real printed VFR
charts, but very few have any non-UK coverage and those that do are
expensive due to the licensing cost of the Jepp VFR/GPS maps.
After messing around with this stuff I eventually concluded that the
best way is a dedicated tablet computer in the cockpit, and a nice but
otherwise very ordinary lightweight laptop for everything on the
ground.
If there was a convertible laptop/tablet with a sunlight readable LCD
that would be perfect, but there isn't and - apart from some oddball
£4000+ military products - there never has been.
However, the OP seems to be only asking about surface use, in which
case any decent laptop will do. I would avoid the £200 netbook
products; I have an ASUS E901 whose keyboard is basically crap. The
best laptops to buy are the corporate-grade ones priced from £1000 to
£2000 but you can get them "refurbished" (which often means the box
was never opened but it is the last year's model) for much less; these
are real quality products (Thinkpads etc).
Post by DanielPersonally I use a Asus Eeepc T91 with a remote bluetooth GPS receiver
and my own navigation software.
It can be transformed into a tablet PC.
The size is just the right one but the screen has too many reflections
and not bright enough to be really usable on a sunny day.
Another advantage, no hard disk but an SSD so theoretically more
reliable at high altitude.
The CPU is ok for in flight moving map computing. The battery last for 3
to 4 hours with my navigation software that takes around 50% of the CPU
when flying.

Post by brian whatcottI am using a Garmin PNA called an iQue (out of production now) loaded
with APIC moving map etc for situational awareness, and a Garmin 90 (way
out of production) for distance to go, Course, track, ground speed with
a GPS remote antenna amp (20dB).
This is a very useful combination for cross country travel to unfamiliar
airports. Larger screen PNAs are now coming available and being taken up
by the soaring community.

Post by AnthonyLI'm asking on behalf of a friend who has his own small plane and flies
around the uk and occasionally abroad. I was hoping for some feedback
of what configuration works well in this situation, however it seems a
netbook would offer more flexibility for combined home/flying use.
Perhaps I should ask "What do you use and find most useful?"
Thanks

Post by PeterWhat apps do you want to run on it?
Any fancy phone will do the 3 things, but not necessarily run any
useful apps.

One possibility is a Netbook with a suitable mobile but wondering what
other options are out there that are easy to carry around whilst
flying around airfield to airfield. Mainly UK.
Many thanks
