N2 takeoff/max is

N2 takeoff/max is

• A. 101-103%
• B. 60-100.1%
• C. 103% max
• D. 95-101%

Answer: (C)

N2 limits show how fast the core spool can turn when you’re delivering takeoff thrust or operating at maximum thrust. N2 is the high‑pressure core speed, and the limits are set as a percentage of the engine’s rated speed. For takeoff and for max thrust, the allowable limit is 103% of that rated speed. This small margin above 100% provides enough thrust and accounts for measurement tolerances while keeping the engine within safe mechanical limits. Pushing beyond 103% risks overspeed, which can lead to damage or compressor instability, so 103% max is the defined ceiling. The other options either suggest lower values or a range that doesn’t match the official absolute maximum, so they don’t reflect the required takeoff/max limit.
