VEB is much better than that
Not so... properly implemented, VEB can be good down to about 150' or 160' HAT if scientifically applied and not subject to politically based constraints. It is only because of outdated policies and "Kentucky windage" that these higher VEB values became limiting. In fact decades ago, we even did air carrier Baro based Cat II, in the 707 DC8 era, before RA was in widespread use. And further, for GA, we had 61.3(h) baro ops that were good to 100'HAT without even dual systems or RA.
