Under SAAT level 3 or lower and field elevation less than 4000 ft, which CRJ variant has a minimum runway length of 5200 ft?

• A. CRJ-2/9
• B. ERJ
• C. CRJ-7
• D. CRJ-200

Answer: (C)

In this scenario, takeoff performance is tied to the aircraft variant, weight, and the environmental/SAAT level conditions. The data used at SAAT level 3 or lower with field elevation under 4000 ft shows that the CRJ-7 requires a minimum runway length of 5200 ft. This longer requirement comes from its heavier operating weight and engine/thrust characteristics, which mean it needs more runway to reach liftoff speed and achieve a safe takeoff climb.

The other CRJ variants listed are lighter and have shorter takeoff distances under the same conditions, so their minimum runway lengths are less than 5200 ft. The ERJ is not a CRJ variant and doesn’t fall into the CRJ performance data used for this comparison.

So, the CRJ-7 is the one that aligns with a 5200 ft minimum runway length under those SAAT and field elevation conditions.
