Narrative:
We are flying an aircraft with a brand X autoplt. The light transport has fairly significant static position and acceleration errors. Whenever we turn or accelerate/decelerate, the static errors create plus or minus 150-200 ft altitude errors that the autoplt does not compensate for.

Title: LTT ON DEVELOPMENT TEST FLT HAS STATIC SOURCE PROBS IN TURNS AND DURING ACCELERATION AND DECELERATION.
Narrative: WE ARE FLYING AN ACFT WITH A BRAND X AUTOPLT. THE LTT HAS FAIRLY SIGNIFICANT STATIC POS AND ACCELERATION ERRORS. WHENEVER WE TURN OR ACCELERATE/DECELERATE, THE STATIC ERRORS CREATE PLUS OR MINUS 150-200 FT ALT ERRORS THAT THE AUTOPLT DOES NOT COMPENSATE FOR.
