The 757 cockpit designers did use the word "intuitive" a lot.

The control stick movements, for example, are intuitive. (Early aircraft did not have control sticks!)

For a crazy example, airplane jargon has specific meanings. "Takeoff Power" officially means full power to take off with. Makes intuitive sense, right? Well, one day the pilot needed to abort a landing, and yelled "takeoff power". The copilot heard "take off power" (note the space), chopped the power, and the airliner crashed. The jargon was changed to "full power".

The Air Force, however, had their own jargon and stuck with "Takeoff Power", until one day they had the same accident and changed the jargon.

For another example, the levers for the flaps have a knob on them shaped like a flap. This way, the pilot has tactile feedback that his hands are on the right lever, and he doesn't need to take his eyes off his other tasks.

For a third example, cockpit designers put in a warning horn for a stall warning. It worked great, and so they put in other warning horns, each with a distinct sound. Unfortunately, the pilots would confuse them, and do the wrong thing. So the "horn" is now a voice that says "stall" (or something like that).

Using words for aural indicators still has not percolated out of the aviation industry. You don't have any for your car, for example. Just chimes, beeps, buzzes, and other primitive and hopeless sounds. Oh, lest I forget to mention, the stupid incomprehensible icons.
