A Marvel of Genius
on November 25, 2011
Anyone who is old enough to remember when a computer didn't mean something electronic, might be able to relate to a Jeppesen Flight Computer. It's like a slide rule that once solved the mysteries of tangents, signs and cosigns in trigonometry. The Jeppesen is the same thing and more and it's round.
I got my first one when I was taking pilot training in my senior year of college. It could calculate true air speed and ground speed, distance, fuel usage, time to destination, and several other calculations you might not use but it was there if you needed it that one time. Soon after I kept it in my glove compartment for long car trips, and as long as I maintained my speed and knew that Birmingham, AL was 230 miles away, I could predict to the minute my time of arrival at the same place.
If you are learning to fly for the first time by Piper Cub or Cherokee, and your airfoil doesn't have an inertial navigation system, this is a must for the student pilot.
It's still a novel experience to know there is a computer that doesn't depend on a charge and gives you accurate information to distance, time, amount of fuel, etc, etc.
This is what seems to be a marvel of genius.
