Visual Balance Safety Chart

Green Line = Your Flight

Both green dots (Takeoff and Empty-Tank Landing) must stay inside the shaded box to remain within factory weight and balance limits.

Why Your DAR Inspector Checks Both Dots:

On most RV and Sling aircraft, the fuel tanks sit ahead of the pilot. Burning fuel in flight shifts your balance rearward. Checking both dots guarantees you won't drift past the rear balance limit before landing.
