PILOT REPORTS BECOMING DISORIENTATED DUE TO UNFAMILIAR ANALOG INSTRUMENTS AND FLIES INTO RESTRICTED AIRSPACE NORTH OF TNP.

Narrative

I DEPARTED PSP FOR ZZZ PLANNED AS PSP TNP EED ZZZ. I WAS A BIT FATIGUED. I HAVE BEEN DOING A GREAT DEAL OF IFR TRAINING IN THE LOS ANGELES BASIN AREA IN A DIFFERENT ACFT (WITH A MOVING MAP). ON THIS FLT; I WAS WORKING WITH SOMEWHAT UNFAMILIAR ANALOG EQUIP. I ASKED FOR FLT FOLLOWING. I THEN DEPARTED HVY WITH A NEED TO DEVIATE SIGNIFICANTLY FROM THE FLT PLAN THAT I HAD PUT INTO THE GPS TO CLB FOR TERRAIN. AFTER CLRING THE TERRAIN; I WAS SUBSTANTIALLY OFF COURSE. I THEN DECIDED TO WORK WITH THE VORS 'FOR SOME PRACTICE.' VOR RECEPTION IS VERY BAD IN THIS MOUNTAINOUS TERRAIN. WHEN I SEEMED TO GET INDICATIONS THAT I WAS OFF COURSE; I CONTINUED TO RELY ON THE GPS WHICH I HAD PUT INTO THE 'DIRECT TO' MODE. I NEVER RE-CTRED THE DEV BAR BECAUSE OF MY DISTR WITH THE NEW AUTOPLT AND THE BOUNCING VORS. THEREFORE; I MAINTAINED A TRACK THAT WAS COMPLETELY INCORRECT. NEXT; I GOT A CALL FROM ZLA INFORMING ME THAT RADAR CONTACT WAS LOST (TERRAIN). I WAS KEPT ON THE SAME BEACON CODE AND TOLD TO EXPECT RE-IDENT IN 10 MI. DURING THE NEXT 5-6 MINS; I BEGAN TO REALIZE VIA PILOTAGE THAT I WAS OFF COURSE N AND W OF MY EXPECTED POS. I DIDN'T REALIZE THAT I HAD GOTTEN SO FAR N AS TO PENETRATE THE RESTR AIRSPACE. I WAS CORRECTING TO THE S WHEN I GOT THE CALL FROM ZLA THAT I WAS IN RESTR SPACE AND NEEDED TO FLY 090 DEGS FOR THE MOST EXPEDITIOUS EXIT. ANALYSIS: FATIGUE PLAYED A ROLE. GOING BACK TO NON-GRAPHICAL NAV EQUIP PLAYED A ROLE. I HAD BECOME TOO DEPENDENT ON THE MOVING MAP. FLT FOLLOWING INCREASED THE DEPENDENCE FACTOR AS WELL. THE 'COUP DE GRACE' THOUGH; WAS THE LOSS OF POSITIONAL AWARENESS THAT CAME WITH UNNECESSARY FIDDLING WITH VORS AND A NEW AUTOPLT.
