The 737 QRH states "Elevator control is sufficient to safely land the airplane regardless of stabilizer position"
BEagle said,
Incidentally, an elevator with sufficient authority to override pitch excursions at extreme stabilizer angles would need to be very large indeed and would make the aircraft very sensitive without some very clever stick force gradient!
Can I take it that when Boeing wrote that they were assuming the aircraft was constantly operated within normal pitch limits, and from what BEagle has said that all airliners currently in operation would be in a similar boat to the A320 with respect to unusual attitudes and extreme THS angles?
