The #A320 aircraft does not have a residual pressure indicator on its forward and aft cargo doors because of a vent door that equalizes the air pressure inside the cargo compartment with the outside when the cargo door is opened.

A safety feature, the red warning light on the cargo doors of an Airbus #A330 indicates residual pressure in the cargo compartment, which is designed to prevent violent door openings that can cause serious injuries.

Since we don’t have this on the A320, how do we mitigate this ?

🔑 There are specific criteria for triggering this partial spoiler extension, which operates independently of the ground spoiler lever position.

🛬 The Phased Lift Dumping function allows the ground spoilers to deploy with a reduced deflection and serves to accelerate the full spoiler extension when landing in crosswind conditions or on contaminated runways.

The innovative feature of Partial Spoiler Extension on the #A320, improves landing safety and efficiency, ensuring better control when the runway conditions aren’t ideal.

Just how robust are these engines !!!!🤯

To safeguard turbine hardware, an operational limit known as the "𝗘𝗚𝗧 𝗿𝗲𝗱 𝗹𝗶𝗻𝗲" is established through endurance testing.

🤔 Ever wonder why the Flight Crew Oxygen system has a 100% oxygen supply, also with a positive pressure ?
