[QUOTE]I'm trying to think of the simplest single reason for the loss. Does the 747 a take-off warning (like the A320) if power levers are advanced with stab trim outside of acceptable range?/QUOTE]
Certainly the 737 does. I would imagine that it is a common feature across all Boeings. Having said that I would think that it a requirement for all public transport aircraft to have this alert as we can see the consequences can be catastrophic.
