I think I'm missing something here. The design standards already have this requirement built into the AFM at certification so, when you check for landing WAT limits, you meet both the approach and landing climb gradient requirements.
Would that be true for higher than standard missed approach climb gradient?ie 2.5% and above?
I was referring to SAFO 06012 which was not disseminated to so called reputable airlines such as the famous 'runway overrun' American Airlines.
AA latest was in 2009 for which finally the NTSB strongly recommended the FAA to update the AC concerning pilots taking in account changing conditions,tailwind in that case/sim training.
I believe jar ops makes it a regulatory requirement to calculate landing distance in flight.
I have yet to be introduced to safo 06012 and this revised AC in my reputable airline as no such training has been given during sim sessions.
