New High Altitude Switch Thread

Not sure why I was locked out for replying to the last thread on this but nobody gave any clear answers so here are the following questions. 1) If the High Altitude switch is currently not modeled that means the max altitude for landing is 8400 ft which is what the Boeing specs say. 2) Even if it was modeled and allowed for up to 12,000 feet it still wouldnt be rated for SLLP at 13,325 ft So therefore technically the only Boeing Aircraft currently rated to take off from SLLP are either the 757 or 787?
