What should be verified during a manual start regarding bleed pressure indication?

During a manual start of the A320, it is essential to verify that the bleed pressure indication falls within the correct range, which is typically indicated by a green color on the cockpit display. This green indication signifies that the bleed system is functioning within its normal operating parameters and that adequate pressure is present to support a successful engine start.

Having a green status means that there is sufficient bleed air available, which is critical for starting the engines, as it provides the necessary airflow to initiate combustion. If the bleed pressure were indicated in a different color (such as amber or red), it would signal a problem with the bleed air system, which could compromise the engine start process and overall safety.

Properly recognizing and confirming the green indication helps pilots ensure that the aircraft systems are verified against safety protocols before proceeding with further operations during the start sequence.
