Which items will be affected if covers over the pitot probes are not removed?

When the covers over the pitot probes are not removed, it primarily affects the flight recorder, airspeed indicator, and autopilot systems. The pitot probes are essential for measuring airspeed because they capture dynamic air pressure, which is crucial for the operation of these instruments.

The flight recorder relies on accurate airspeed data to log performance information, which is vital for analyzing the aircraft's performance during flight. Similarly, the airspeed indicator needs data from the pitot probes to display the correct airspeed to the pilots, allowing them to maintain appropriate control of the aircraft. The autopilot system also utilizes airspeed for various functions, such as maintaining altitude and speed during flight.

Other systems, like navigation systems or cabin pressure alarms, do not rely directly on data from the pitot probes, making them less affected in this scenario.
