Let's not go where this is headed....another EC/SK Oh Yeah....Oh Yeah.... bunch of bickering!
Let's discuss the certification process....the definition and implementation of "extremely remote"...and perhaps the wisdom of a allowing a waiver from the 30 minute run dry concept.
It seems simple to me....either you meet the 30 minute run dry test as required by Part 29 or you do not get the certification. The use of a waiver in itself connotes being unable to meet the requirement.
