When it comes to General Aviation aircraft and flying, it seems far too many rules are out of date.
Makes you wonder if the chap who wrote then all in 1945 has died, and no else has been allowed to pick up his ball.
Loran, GPS, Computer controlled engines, Transistorised ignition, Composite airframe certification requirements, reliable transistorised radio's, and the archaic WWII method they are employed, in fact almost everything introduced into service, since 1945!
Or could it be, it is the same man, who in spite of every advance still see's, in his very 'British' way, 'no need' to change what he has already written.
It makes no sense to require out dated, obsolete equipment, when far better technology is available, but not 'approved' for use.
One day someone will die because of it.
