This forum discussion presents a compound emergency scenario that instructors and check airmen regularly use to stress-test crew resource management under maximum workload: a Low Visibility Operations (LVO) approach at 500 feet AGL disrupted simultaneously by captain incapacitation and an unextinguished engine fire following completion of memory items. While hypothetical, the scenario is a realistic simulator training construct because it forces a single remaining pilot to manage flying duties, decision-making authority, and emergency response coordination at the worst possible moment—inside decision height on a low-visibility approach, with no functioning second pilot to share workload or serve as a check on decisions.
The core technical challenge is sequencing. The first officer, now sole manipulator of the aircraft, must complete the approach and landing (likely hand-flown or with heavy autoflight reliance depending on autoland capability and LVO certification), declare an emergency, and prepare the cabin and ATC/ARFF for a high-risk arrival, all while the engine fire persists despite bottle discharge. Most operators' SOPs and QRH guidance state that if fire indications persist after both fire bottles have been discharged, the crew should plan for an evacuation upon stopping rather than assume the fire will self-extinguish. This is where the discussion's central question becomes operationally significant: whether to order an immediate evacuation with fire still active, or hold position for ARFF to knock down the fire before making the evacuation call. Most airline SOPs favor immediate evacuation when fire is confirmed and uncontained, because structural fire progression, wing tank proximity, and smoke ingress into the fuselage pose a greater cumulative risk than evacuation injuries. However, some carriers' evacuation checklists explicitly weigh a "control the response, don't rush" decision framework, especially if ARFF is on scene within seconds and can suppress the fire before doors open—an approach influenced by post-accident studies (e.g., British Airtours 1985, various runway excursion events) showing evacuation-related injuries are common and sometimes more severe than the fire threat itself if handled without full command authority.
The third dimension raised—directing evacuation away from the fire side only—reflects an established SOP concept found in most flag carriers' evacuation checklists and cabin crew procedures: crew are trained to assess each exit for fire, smoke, or hazard before opening it, and the flight deck or purser will call out "evacuate, evacuate, [side/exits] only" over the PA when hazard-side exits must be blocked. Coordinating this correctly requires the surviving pilot to communicate a clear, single directive to cabin crew rather than relying on ambiguous phraseology, particularly because with the captain incapacitated, there is no PF/PM division of labor and no second pair of eyes to catch a garbled or delayed command. This is precisely why full-motion simulator training scenarios combine incapacitation with mechanical emergencies: they test not just system knowledge but authority transfer, radio/PA discipline, and single-pilot decision-making under compressed time.
For working pilots, the value of this thread lies less in the specific "right answer" than in the exposure of variability across operators' SOPs, training philosophies, and cultural approaches to CRM. Some fleets emphasize captain authority transfer procedures explicitly briefed during preflight (particularly relevant on LVO-authorized aircraft where CAT II/III approaches already carry stricter crew role requirements), while others leave incapacitation response more generically covered in recurrent training. The broader trend here connects to industry-wide emphasis on single-pilot incapacitation drills, evacuation decision-making research following high-profile events (Aeroflot Sheremetyevo 2019, Emirates Dubai 2016), and increasing regulatory scrutiny of how airlines train evacuation authority, non-standard phraseology, and ARFF coordination. As more carriers push LVO capability and reduced-visibility operations into daily line flying, incapacitation-plus-emergency scenarios like this one are likely to remain a fixture of type-rating and recurrent simulator syllabi, reinforcing that CRM training must extend beyond two-pilot cooperation to cover degraded-crew contingencies as a core competency.
