The altimeter is the correct choice because it measures the static pressure in an aircraft's static pressure system, as required by FAR Section 91.411. This system is responsible for providing accurate altitude readings, which is crucial for safe flying. The other options, such as the vertical speed indicator, heading indicator, and turn and slip indicator, do not measure static pressure and therefore cannot be used to test the static pressure system. In fact, using any of these instruments instead of an altimeter could result in inaccurate readings and potentially compromise the safety of the flight.
