OK,
I did note the article as having many incorrect assumption, OPD/CDA will keep the ac higher longer, and ideally, will use a 3 degree GPA from TOD, keeping the ac higher than the step downs.
My question was regarding the validity of the failed safety case, and issues overseas....
You seem to be saying that there is a difference between CDA and OPD....
Isnt OPD just the newer nomenclature under NextGen?
