For an interior attack, where is the best first interior attack line location?

• A. Front door at ground level
• B. Through the cockpit window
• C. From the tail cone
• D. An upwind over-wing hatch or door, with enough hose to reach the cabin length

Answer: (D)

Access for the first interior attack should come from an upwind over-wing hatch or door, with enough hose to reach the full cabin length. This spot places the nozzle team in cleaner air, protecting them from the densest smoke and hottest gasses, and gives a direct path toward the fire so you can advance quickly along the cabin. Having sufficient hose length is essential because the fire can extend far through the cabin, and you need to reach the far end without having to retreat or reposition prematurely. Entry through the cockpit window or tail cone and front ground-level doors are less practical due to access issues, higher risk, and potential blockages, making the over-wing entry the most effective option for an interior attack.
