Hi all,
The obvious thing to do is land with flaps 10, there is a procedure in the B737 QRH for that, it's the same one!
Land at Vref 40 + 30, the LEs are all out, so whats the problem?
Yes, the B747 Classic did have the assy detection in the indicators as has been mentioned, but then, they also had a Flight Engineer!
Cheers
