In Class E (Cargo aircraft only) operations, dangerous goods must be segregated from each other whenever they are what?

• A. Stowed on an aircraft
• B. In transit
• C. Shipped together
• D. Unsecured during taxi

Answer: (A)

In Class E cargo operations, the rule focuses on preventing interaction between dangerous goods while they are on the aircraft. Dangerous goods must be segregated from each other whenever they are stowed in the aircraft’s cargo compartments and secured for flight. This separation protects against leaks, spills, or chemical reactions that could arise if incompatible goods are in proximity during the flight.

Think of it as keeping potentially reactive or incompatible shipments apart once they are loaded and secured on board. The option about being in transit on the way to destination isn’t the moment this particular requirement applies, and shipping together or having goods unsecured during taxi either contradicts the segregation principle or relates to different safety concerns on the ground.
