Jet is single pilot certified with autoplt required. Aircraft was 90 hours since new. Multiple autoplt problems. It doesn't handle speed changes very well. Multiple autoplt inoperative lights. You have to cycle flight guidance circuit breaker to restore autoplt. When you do, primary flight instruments (attitude indicator and HSI) drop off and reset (takes 3-5 seconds to reset). It dumps all inputs and you must re-enter. Also, it tends to make aircraft skid through the air. Manual trim inputs often cause autoplt to kick off with sudden control inputs. Occasionally, the ball will slowly 'walk' back and forth from side to side with attendant out of trim flight condition.
Original NASA ASRS Text
Title: ACFT EQUIP DESIGN PROB ON CPR SMT JET.
Narrative: JET IS SINGLE PLT CERTIFIED WITH AUTOPLT REQUIRED. ACFT WAS 90 HRS SINCE NEW. MULTIPLE AUTOPLT PROBS. IT DOESN'T HANDLE SPD CHANGES VERY WELL. MULTIPLE AUTOPLT INOP LIGHTS. YOU HAVE TO CYCLE FLT GUIDANCE CIRCUIT BREAKER TO RESTORE AUTOPLT. WHEN YOU DO, PRIMARY FLT INSTS (ATTITUDE INDICATOR AND HSI) DROP OFF AND RESET (TAKES 3-5 SECONDS TO RESET). IT DUMPS ALL INPUTS AND YOU MUST RE-ENTER. ALSO, IT TENDS TO MAKE ACFT SKID THROUGH THE AIR. MANUAL TRIM INPUTS OFTEN CAUSE AUTOPLT TO KICK OFF WITH SUDDEN CTL INPUTS. OCCASIONALLY, THE BALL WILL SLOWLY 'WALK' BACK AND FORTH FROM SIDE TO SIDE WITH ATTENDANT OUT OF TRIM FLT CONDITION.
