Cabin Door Unlatch During Takeoff Roll

FAA Ref: FAA-S-ACS-6C Area IX Task C (Systems and Equipment Malfunctions)

Scenario & Physics Summary

Decision matrix: aborting takeoff below rotation vs flying the airplane first, maintaining altitude, and securing the door at safe altitude.

Aerodynamic & Operational Physics

An unlatched door pops open 1-3 inches due to low pressure over the cabin roof (Bernoulli suction). It will NOT fly off or jam flight controls.
Distraction is the primary killer. Attempting to slam the door on takeoff roll causes control displacement and runway excursion.
If below V_1/rotation speed, abort. If airborne, FLY THE AIRPLANE, climb to safe altitude, trim, and unlatch/slam firmly or land.

FAA Exam Gotcha Alert

Exam Trap: Never compromise aircraft pitch/bank control on climb-out to secure a open door. A popped door has zero aerodynamic effect on flight capability.

Frequently Asked Questions & Exam Explanations

Will an unlatched door cause a plane to crash?

No. The door only opens 1-3 inches due to low external pressure. The danger is pilot distraction leading to loss of control.
