Who came up with the 1500AGL idea.
So dumb on so many fronts.
Over a lot of the East Coast terrain, there is no way your climb and decent rates could match the terrain,
Tracking that height, how do you do that accurately? From a map, not likely, so you need a GPS with terrain overlay with integrated altimeter.
Transiting airfields at circuit arrival height, what could possibly go wrong. 😧
1500AGL gives 90 seconds give or take, if the engine stops. Which depending on your best glide gives you 3km of range, give or take. Not a lot of time or area to pick a spot.
Why not pick an achievable figure, say 5000ft AMSL
I assume they know that 1500AGL isn't achievable and it's their way of making everyone get a transponder or EC device so they can fly in Class E, but they can claim that they have still left some Class G for those that don't have them, even though that Class G is mostly unworkable.
