For high-speed aircraft, the standard rate turn is 1.5 degrees per second.

• A. 0.5° per second.
• B. 1.5° per second.
• C. 3° per second.
• D. 4.5° per second.

Answer: (B)

In high-speed flight, how quickly you turn is tied to two factors: bank angle and airspeed. The rate of turn increases with bank and decreases as speed goes up. To keep turns within safe structural limits on fast jets, the practical standard rate is set gentler than in slower airplanes. About 1.5 degrees per second yields a predictable, manageable turn that avoids excessive bank or load factors at high speeds. That rate takes roughly four minutes to complete a full circle, offering a steady reference for maneuvering and airspace management. Rates like 0.5°/s would be unnecessarily slow for coordination, while 3°/s or 4.5°/s would require larger banks and higher loads than is typical for high-speed aircraft.
