To what PSI is high-pressure bleed air regulated?

High-pressure bleed air is regulated to a pressure of 36 PSI, with a tolerance of plus or minus 3 PSI. This regulation is essential for various aircraft systems, including pneumatic systems that depend on bleed air for operations such as air conditioning, de-icing, and engine starting.

Maintaining this specific pressure range ensures that the systems relying on bleed air function efficiently and safely. If the pressure were to exceed this range, it could lead to system failure or damage, while lower pressures might not provide sufficient power for the intended operations. Hence, the 36 ±3 PSI standard is critical for operational integrity and safety in aviation contexts.
