Do you people with GPS units (either panel mounted or portable) use only them when you fly, or do you plan the same route on a map as well and plot your position in flight, for backup in case the unit looses pickup? I've I draw the route on the chart. Given the endurance of the Cub (12 gallons, 4.2 GPH) I'm simply not traveling far enough to use checkpoints. I always know where I am on the chart, and I have a decision point of one hour, with due allowance for the wind. The plane has no Hobbs meter, and rather than using the tach as most people do, I write the engine-on time on the back of an obsolete business card, stuck up under the top clip of the kneeboard. That's the only paperwork I do. all the best -- Dan Ford email: www.danford.net/letters.htm#9 see the Warbird's Forum at http://www.danford.net/index.htm Vietnam | Flying Tigers | Pacific War | Brewster Buffalo | Piper Cub |

Even if VFR a map is a must, never trust any electronic gadget 100%. Even with
redundant systems there is a potential loss of electrical power.

I've recently seen the SR-22 panel and some Lancair models and it got me wondering whether aside from all these hi-tech gadgets people still use the good old roadmap. Triple Delta |
