Balanced field length applies to which scenario?

• A. Single-engine takeoffs.
• B. Multi-engine takeoff with one engine inoperative.
• C. Multi-engine landing.
• D. Taxi distance.

Answer: (B)

Balanced field length is the runway length at which the takeoff distance with all engines operating equals the landing distance with one engine inoperative. This concept ensures a single runway can safely accommodate both taking off and, if an engine fails, continuing the operation and landing within the same distance. It specifically applies to multi-engine aircraft because engine-out performance during takeoff is the limiting factor. Therefore, the scenario described is a multi-engine takeoff with one engine inoperative. The other options don’t involve the engine-out takeoff performance or are unrelated to this balance.
