Why we need regulated voltage in our aircraft and how zener diodes, resistors, transistors and semiconductors help us get there.
Now that you've fabricated your seat upholstery, its time to tackle the rest of the interior with a look at carpeting and door panels.
Its important to understand the fundamentals before you can be conversant in electrical theory, so lets revisit Georg Simon Ohm and James Watt to see how their laws factor in to aircraft applications.
Now that the foam is cut and glued, we’ll learn how to make the pattern, choose and cut the fabric, and sew the cover.
