If cargo is carried in either compartment, how many minutes must the aircraft be from a suitable airport?

When cargo is carried in either compartment of the CRJ 900, the operational limitation specifies that the aircraft must remain within a certain distance from a suitable airport for safety reasons. This limitation is set at a maximum of 60 minutes flight time from a suitable airport. This is essential to ensure that in the event of an emergency or if any issues arise concerning the cargo, the aircraft can divert to a nearby airport without significant delay. Maintaining this proximity helps ensure the safety of the flight crew, passengers, and any cargo on board.

The other options, while they represent time frames that might be considered for various operational limits or scenarios, do not align with the specific cargo policy of the CRJ 900, which is firmly established at 60 minutes.
