The term "cycle" can mean all sorts of things. One "cycle" of anything usually means that some sort of operation has begun, run through it's full function, with the intended operation finally terminating successfully....one complete cycle. An aircraft taking-off and landing successfully constitutes "one cycle" in the airplane world. This term usually applies to larger aircraft which take-off and go through ONE cycle of pressurizing the hull, depressurizing again and eventually landing. The landing gear has been cycled up AND down "X" number of times. The air conditioner completes a cycle when the compressor comes on-line, removes heat from your truck's interior to the point of satisfying the thermostat, and shuts-off! Your electric company bills you through twelve cycles of usage annually.


So, your above statement needs just a little re-evaluation. DD
