737-300 Failed Flap System
Hypothetically speaking,
If your normal Flap system fails at Flap 5 (Hydraulically powered system B), due to a faulty signal from the flap indicator (fails safe to stop asymmetric flap extension), you used the Alternate flap extension system (Electrically driven), and that too failed at flap 10. You are going to land fast, but no great drama.
My question is, if the aforementioned flap indicator was changed by the engineers, and problem rectified, what could have caused the Alternate flap system to fail too? These are supposed to be 2 independent systems are they not?
Any feedback gratefully received.
