I flew over to Cambridge last week Tuesday and was carrying my "first passenger". I planned the flight manually using the CRP-5, Wind Corrected and noted it all down on a Pooleys VFR PLOG.

As a precaution I also took out a sub to SkyDemon to run on my Android Phone - only to find that you are able to "plan and print the PLOG" also and use this for your flying. The only time I needed to use SkyDemon was to confirm I was actually overhead Chedburg turning en route to Cambridge.

Having it on my lap gave me the piece of mind that should I not know where I am I can always look at the Sky Demon.

I had my half mil chart with track over the Ground with half way points and drift lines marked.. One thing I noticed when comparing both SD PLOG and my Manual PLOG was that in my Manual planning - I didn't "interpolate" the Wind at 2000ft for each leg according to Lat/Long - and used the 2000ft wind at my home airfield for the whole journey.

I found that the headings from SkyDemon/Wind was different to my "Manual Calculations".. only by +/- 1 to +/- 3 degrees. I still got to Cambridge flying my manual PLOG and then experienced "flying only GPS" for the journey back to base. Again I noticed how my much mental capacity was released to fly the plane - when doing things by GPS only.

However, I would always like to know where I am visually also - by reference to towns/rivers/railways etc.

How "accurate" is the PLOG on SD and if using such navigational tools, should one also do everything manually or just print off the PLOG from SkyDemon?

I am just thinking time wise - I could have saved myself the planning time but of course I am trying to do everything the way I was taught manually. Though the arguments by some instructors are also - we teach you to fly manually but wouldn't blame you if you were to fly via using a GPS later due to controlled airspace restrictions.

Also - can I review my route that I actually flew using SkyDemon if flying manually (some kind of trace)?

I am still getting to grips with making sure SkyDemon has the correct config for my aircraft because it seems to default to 3000ft when I was at 2100ft which I couldn't change..

Also I don't understand what the "Virtual Radar" is - better read the manual I suppose.

Ta!
