GPS v's Good ole Nav

Right there has been a couple of threads where we argue the pro's and con's of GPS and if they make us lazy pilots or make us depend on them.

Bose-X and myself have decided to do a little test, and to share the whole experience.

The plan is for us to plan a flight and then go and fly it (in the same plane). One of us will follow the plan the other will follow the GPS. we are going to see if we can get each other lost. Hopefully we can dispell any theory that we become lazy for forget how to navigate.

Does anyone have any suggestions on how to make this more entertaining?

Or is anyone intertested in hearing about the experiment.

What are you trying to prove? Turn the GPS off and I bet one of you gets lost

Are you going to do it in an area that neither of you are familiar with?

No point in doing it in an area you are reasonably familiar with

I would definatley pick an area neither of us are familiar with. So the North west is pretty much a no go, the midlands is pretty much a no go and the South West is pretty much a no go. For me it leave the South east or Scotland


As for what are we trying to prove.

1) There should be a seemless transition going from GPS to Map and compass and vice versa with out circling while trying to find where you are.

2) A GPS pilot can still read a map and navigate as efficiently and accuratley as a good ole navigating pilot.

Call an unscheduled diversion ½ way through and then simulate total electrical failure inc any batteries. Should sort one of you out!

1. To make it as realistic as possible I assume you will be solely using either one or the other and then swopping with no cross referencing?

2. Of course he can. Provided he's kept his traditional skills up to scratch.

Good luck

Try a flight something like Stapleford - Ipswich - Cambridge.

Flat, fairly featureless and a host of disused and used airfields. Even better in not brilliant visibility

Write it up for one of the mags and take lots of groovy pics. Should pay for the fuel at least.

I bet Philip Whitehead at Flyer will go for it. Give him a ring.

Bose-X/gcolyer,

Here's a routing for you.

Seething to Peterborough/Conington to North Weald and back to Seething. Get them lost over the fens somewhere, or inbetween Lakenheath and Marham MATZ. That will sort the question out.

Are you going to be allowed to use VOR, NDBs etc? Or is it simply map and stopwatch?

Stapleford - Wycombe/Booker - Cranfield - Duxford - Stapleford.

And at a time unknown to him/her in advance, the GPS pilot is told to switch off the GPS (simulate GPS failure). I'm all in favour of GPS, but the critical issue is: flying near to complicated CAS, can you cope when it stops working?

All this talk of getting lost over the fens is absolutely fine, provided that you pick a low vis day and fly low. Then indeed one twisty little road and twisty little stream and twisty little village does look exactly like the next one, particularly with 5km visibility from 1500' and "the next one" being 6km away.

On a clear day from FL95 you can see the whole of East Anglia. No navigation is needed other than "oh look, there's Norwich, it's around 30 miles away, there's no military airspace at this height, just point at it and go". (OK, so the 172 does take a while to get up there, but you get a whole different view of the world.)

Good question, we need to agree on this one. Maybe for triangulation if one is momentarily misplaced on the map

But then again. VOR's and NDB's are covered all be it breifly for the PPL.

True, that also goes for the majority of the UK. Get up high enough on a clear day and you can always see a major landmark. I do a lot of flying around Suffolk and Norfolk and I still have some problems spotting airfields in amongst the patchwork of fields, even if I can see Norwich!

I thought this was between GPS and dead reckoning?

I am pretty easy either was as it will be an interesting experiment. But I am guessing we should be sumulating the tools that are available to the average PPL without GPS. So we should establish what is available to the average PPL.

In my microlight days we only had a 1/4mil map a compass and stopwatch not even a DI!

1... Include a CAA Examiner in the back seat and call it a 'CPL skills test'

2... Include the Vale of Eden in the flight plan on a busy weekday in good VMC conditions and see how many RAF jets try to put you off
