The correct answer is: C. ART, MRV required at out station
The sounding of 5 hooters means that an aircraft is required to undergo an ART (Aircraft Rescue and Fire Fighting) and MRV (Minimum Equipment List) check at the out station. This is because the aircraft has either experienced a mechanical issue or has been involved in an incident that requires these checks to be carried out.
ART checks are carried out to ensure that the aircraft’s fire-fighting equipment is in working order and that the crew is familiar with the procedures for using it. MRV checks are carried out to ensure that the aircraft is airworthy and that all of its required equipment is in good working order.
If an aircraft is required to undergo an ART and MRV check, it will usually be grounded until the checks have been completed. This can cause delays for passengers and can also impact the airline’s operations.
