What type of system provides feedback on an aircraft's speed and altitude?

The correct choice is the pitot-static system, which is specifically designed to measure and provide feedback on an aircraft's speed and altitude. This system operates using two main components: the pitot tube and static ports. The pitot tube measures dynamic pressure, which is related to airspeed, while the static ports measure atmospheric pressure, allowing for altitude determination.

The data from these components are crucial for the aircraft’s airspeed indicator, altimeter, and vertical speed indicator, thereby giving pilots essential information regarding their flight performance. Understanding the function of the pitot-static system is vital, as any malfunction or blockage can lead to erroneous readings, potentially compromising flight safety.

In contrast, the electrical system primarily powers the aircraft's components and systems, the navigation system is focused on determining the aircraft's position and guiding it safely to its destination, and the fuel system manages the fuel supply to the engines. While all these systems are essential for aircraft operation, they do not provide the specific feedback on speed and altitude that the pitot-static system does.
