What surprises me here, in view of the critical importance of WOW signals, is that there is no
WOW Disagree Warning; for example, between Nose and Main Gear.
The only time that they
should disagree is on Rotate or initial Landing.
The simple answer is to feed all WOW signals to a simple Comparator, with a 10 second ‘disagree’ time delay to a WOW annunciator. Does any manufacture already do this. Surely!
