Step-by-step explanation:
When the main landing gear tire pressure is below 179 psi, the appropriate action to take is to inflate the tire to the correct pressure.
Tire pressure is crucial for the safe operation of an aircraft. If the tire pressure is too low, it can lead to poor handling, decreased braking efficiency, and increased wear and tear on the tire.
It is important to regularly check and maintain the tire pressure according to the manufacturer's specifications to ensure the safe and efficient operation of the aircraft.
