Narrative:
Departed smo VFR to boi. Checked FSS for WX prior to departure. Route of flight: smo-mina-boi. Checked WX in vicinity of bishop and boi changed to possible IFR at my ETA for boi. At mina I elected to land at wmc for fuel in case boi became IFR for extra margin of fuel. To ensure clearance of restr area, I used plotter and WAC chart for distance and radial, 360 degrees and 40 NM off mina VOR for landing at wmc. In haste, apparently I read sectional distance instead of WAC distance from the plotter. Human performance considerations: approximately 1 hour before departure I had a very upsetting argument with my child, which left me very emotionally upset. My emotional condition was probably the primary factor in not being more thorough in my navigation calculations.
Original NASA ASRS Text
Title: PLT OF A BEECH BONANZA V35 INADVERTENTLY PENETRATED RESTR AIRSPACE DURING A XCOUNTRY VFR FLT DUE TO MISCALCULATION OF THE RTE AND MILEAGE.
Narrative: DEPARTED SMO VFR TO BOI. CHKED FSS FOR WX PRIOR TO DEP. RTE OF FLT: SMO-MINA-BOI. CHKED WX IN VICINITY OF BISHOP AND BOI CHANGED TO POSSIBLE IFR AT MY ETA FOR BOI. AT MINA I ELECTED TO LAND AT WMC FOR FUEL IN CASE BOI BECAME IFR FOR EXTRA MARGIN OF FUEL. TO ENSURE CLRNC OF RESTR AREA, I USED PLOTTER AND WAC CHART FOR DISTANCE AND RADIAL, 360 DEGS AND 40 NM OFF MINA VOR FOR LNDG AT WMC. IN HASTE, APPARENTLY I READ SECTIONAL DISTANCE INSTEAD OF WAC DISTANCE FROM THE PLOTTER. HUMAN PERFORMANCE CONSIDERATIONS: APPROX 1 HR BEFORE DEP I HAD A VERY UPSETTING ARGUMENT WITH MY CHILD, WHICH LEFT ME VERY EMOTIONALLY UPSET. MY EMOTIONAL CONDITION WAS PROBABLY THE PRIMARY FACTOR IN NOT BEING MORE THOROUGH IN MY NAV CALCULATIONS.
