Math for A&P Students: The Formulas You Actually Need to Know A lot of A&P students get nervous when they hear the word math. That is understandable. Aviation maintenance math can show up in several different areas: weight and balance, electrical circuits, torque, measurement, area, volume, ratios, percentages, and unit conversions. The good news is that A&P math is not advanced math. You do not need calculus. You do not need complicated algebra. What you need is a solid understanding of the basic formulas that aircraft mechanics actually use. ...

Electrical troubleshooting is one of those A&P subjects that can feel confusing until you slow down and break the circuit into smaller parts. One of the most important circuit types to understand is the series-parallel circuit. A series-parallel circuit is exactly what it sounds like: it is a circuit that contains both series sections and parallel sections. Some parts of the circuit have only one path for current. Other parts of the circuit have multiple paths for current. ...
