No ground power is available at the airport\n2. Only disabled passengers (maximum two) and their carers remain on board—all other passengers have left\n3. Specific safety procedures are followed, including:\n   - Staying only during daylight hours\n   - Flight attendant gives detailed evacuation briefing to remaining passengers\n   - Flight attendant stays in the cabin\n   - Cabin door stays open\n   - Equipment for helping disabled passengers exit must be ready at an open door\n\n**Why it matters:**\nThis direction ensures emergency exits remain visible and accessible during ground operations, reducing the risk of passengers being trapped if an emergency occurs while the aircraft is parked. The exception allows flexibility for assisting passengers with disabilities while maintaining safety through alternative measures."},"flash_summary_failed":{"failed":true,"reason":"Unauthenticated.
