What precaution should be observed when washing an airplane?

Washing an airplane requires special care to protect sensitive areas, particularly components such as static ports, antennas, and control surfaces. Static ports are critical for accurate airspeed and altitude readings as they measure ambient air pressure. If these ports become blocked or contaminated with soap, water, or debris, it can lead to incorrect instrument readings, which can compromise flight safety.

By ensuring that sensitive areas are protected during the wash process, technicians help maintain the aircraft’s operational integrity and ensure the safety of the flight crew and passengers. Properly safeguarding these areas is essential to prevent malfunction and to uphold the standards required for aircraft maintenance.

While other precautions, like avoiding high-pressure washing and washing in direct sunlight, have their merits, the specific safeguarding of sensitive components stands out as a critical focus for effective aircraft maintenance.
