Landing Gear
On fixed main landing gear how does an airplane get WOW signal. Where did they put the WOW sensor?
I have seen on other oleo-strut airplanes that they have put on the strut. When the ground loads on landing gear occur strut displacement changes and by a proximity sensor they get wow signal. I couldn't understand ; how do they get wow signal from a leaf spring type main landing gear. Thanks,
The Cessna 172RG for example has a WOW sensor located on the nose gear, since it is the oleo type which lends itself to WOW switches much more easily. This isn't as good of a solution as putting the switch on one or both of the main gears, however, as the nose gear can fully extend during taxi or takeoff roll before rotation, and if the gear handle happened to be up, so goes the gear. But, it is better than nothing at all.
