Aircraft operating systems can also overlap and cause problems. This is particularly
true of the electrical and hydraulic systems involving the landing gear and control
systems. This relationship is extremely important. In one incident, a pilot had a
total electrical failure in an aircraft that had an electrically operated landing
gear system. After the gear-up landing, the pilot said that he knew that the gear
down indicators would not work becuase they were electrically operated. He thought
the gear was down because the manual indicator showed it was down after he had put
the gear handle in the "down" position. When asked if he had lowered the
gear manually, he said, "No." If this pilot had possessed more insight
into the interrelationship between systems, it is possible that he could have avoided
this incident.
We mentioned avionics systems. Fatal accidents have occurred because pilots set up
their navigation and communication systems improperly. No more needs to be said!
