Which statement best summarizes the A220 door pre-flight procedures?

• A. Only the arming status is checked
• B. Disarm status, seal condition, and slide gauge are checked
• C. Only the slide gauge is checked
• D. The door is opened for inspection

Answer: (B)

Door pre-flight checks on the A220 are about confirming three key conditions: the door is disarmed, the seal is intact, and the slide gauge indicates the slide is present and properly stowed. Verifying the disarm status prevents any unintended slide deployment during normal ops, which is essential for safe handling on the ground. Checking the seal condition ensures the door retains its proper weather and pressure seal, guarding against leaks and damage that could affect cabin integrity. The slide gauge verification confirms the evacuation device is present, in the correct state, and ready to deploy if needed. These three elements together ensure the door can be opened and closed safely, remains protected from environmental factors when not in use, and can evacuate passengers effectively in an emergency. Focusing on only one aspect or omitting any of these checks could leave a safety gap—for example, a door could be disarmed but have a damaged seal or a missing slide, or vice versa. Opening the door for inspection isn’t part of the standard pre-flight sequence for this door.
