During initial take-off climb or go-around, what Pitch/N1 settings are recommended between sea level and 15,000 feet and above 15,000 feet?

During initial take-off climb or go-around, what Pitch/N1 settings are recommended between sea level and 15,000 feet and above 15,000 feet?

• A. 10 degrees TOGA from sea level to 15,000 feet; 5 degrees CLB above 15,000 feet
• B. 5 degrees TOGA from sea level to 15,000 feet; 3 degrees CLB above 15,000 feet
• C. 15 degrees TOGA from sea level to 15,000 feet; 7 degrees CLB above 15,000 feet
• D. 0 degrees TOGA from sea level to 15,000 feet; 2 degrees CLB above 15,000 feet

Answer: (A)

During initial takeoff climb or a go-around, you want to couple maximum climb performance with later efficiency as you gain altitude. Using TOGA thrust with about a 10-degree nose-up pitch early on provides a strong climb rate and reliable acceleration, helping you achieve the required airspeed quickly and clear obstacles. Once you’re above 15,000 feet, the air is thinner, so a slightly flatter attitude with CLB thrust—around 5 degrees—keeps the climb stable and efficient without overworking the engines. The other options either under- or over-pitch for the situation, risking insufficient climb performance at low altitude or an overly aggressive, unsustainable climb as you rise.
