What tools are typically used to check control surface travel?

The use of a universal propeller protractor is particularly suitable for checking control surface travel because it is specifically designed to measure angles and can provide precise readings of the travel angles of control surfaces such as ailerons, elevators, and rudders. This tool allows for accurate adjustments to be made in accordance with the manufacturer's specifications, ensuring that the control surfaces perform correctly and safely.

In contrast, a compass and level are generally used for orientation and establishing horizontal surfaces and would not provide the necessary measurements for control surface movement. A stopwatch and ruler would focus more on timing and linear distance rather than angular measurements crucial for control surface travel. A laser measuring tool could be useful for distance measurements but lacks the angle measurement capability required for this specific application. Therefore, the universal propeller protractor is the most effective tool for ensuring accurate control surface travel assessments.
