In driftdown calculations, the goal is to ensure there’s a safe vertical margin for the aircraft after an engine failure as it follows the planned route. Method 1 specifies a fixed criterion: the engine-out net flight path must clear by 1,000 feet within five statute miles of the planned route. This exact criterion defines Method 1, so the statement that describes this 1,000-foot clearance within five miles is the best match. The other method uses a different criterion for obstacle clearance, so it does not describe the same condition.
