Aeroperu 601 with blocked static ports worse than AF447

Although the post to which you were replying incorrectly stated that the Aeroperu 603 crash was caused by the aircraft stalling on account of the wrong PITCH was incorrect, the aircraft did finally stall.

As pointed out in my book Air Crashes and Miracle Landings--60 Narratives the Aeroperu pilots flew out over the sea for safety (and presumably because there would be no mountains there did not use their radio altimeter). Not realizing that the altitude of 9,700 ft confirmed by ATC was merely that given out by their transponder in turn dependent on the barometric altimeter (not working properly due to the blocked static ports) flew into the sea.

The aircraft bounced and rose 200 ft before STALLING, inverting and falling back into the sea. Although one of engines had ingested some water on initial impact with the sea and was impaired, it might have been have been a different story had the engines not already been throttled back due to a spurious overspeed warning and had no time to spool up.

As you rightly said, blockage of the static ports is even more serious than blockage of the pitots. The AF447 pilots could see that after a considerable climb (causing the a/c to stall) they were falling downwards which is more than the Aeroperu pilots could. In the circumstances they (Aeroperu pilots) did well.
