How many fuel probes are in each wing?

How many fuel probes are in each wing?

• A. Nine
• B. Eleven
• C. Thirteen
• D. Fifteen

Answer: (B)

Fuel quantity sensing relies on a distributed network of probes embedded in the wing tanks so readings stay accurate as fuel shifts during flight. The probes provide coverage across the tank’s sections and redundancy if a probe fails, ensuring reliable data for total fuel, center of gravity, and fuel management. For this aircraft, there are eleven probes in each wing. That arrangement gives fine enough measurement resolution across the wing’s geometry and is the installed configuration documented for the airplane. Fewer probes could miss variations in fuel level; more would add unnecessary complexity without a proportional gain in usefulness.
