Which aircraft has TAS 400?

• A. Canadair Jet CRJ200
• B. Boeing 717-200
• C. Airbus A320
• D. Embraer EMB-145

Answer: (A)

TAS, or true airspeed, at cruise is influenced by aircraft size and design. Smaller regional jets typically cruise slower than the larger airliners, so their true airspeeds sit lower on the spectrum. The Canadair CRJ200 is a compact regional jet, and its typical cruising speed tends to be around 400 knots or a bit higher depending on altitude and weight. In contrast, the Boeing 717-200, Airbus A320, and Embraer EMB-145 are larger jets that usually cruise faster, with true airspeeds commonly in the neighborhood of 450–480 knots or more at standard cruise levels. Because the statement specifies TAS around 400 knots, the CRJ200 is the best match among these options. Keep in mind that actual TAS depends on altitude, weight, and flight conditions, so numbers can vary, but the regional jet’s lower cruising speed makes it the most likely to be near 400 knots.
