All the issues with airspace infringements we've had as a club over the last few years have been luddite duffers flying with maps as primary nav.
We as a club, are probably going to decline to tow people who don't have electronics as primary nav in the near future.
A map is useful to have, to keep the sun off, poke bugs off the wing through the DV panel, additional insulation above FL150, absolutely useless in this day and age for primary nav.
Bluster all you like about stopwatches, dead reconing and 1/4mil maps, life has moved on, if that is your primary nav, you are exercising poor airmanship and are a danger to all around you.
