Narrative:
Cleared by departure to fly heading 060 degrees to intercept 090 degree right dallas 6. I thought I had set VOR intercept on the flight management panel (automated cockpit). Next heard center (after frequency change) say turn right 100 degrees to intercept 090 degree right dallas 6 departure. I had gone through the radial (not more than 5-10 mi due to X angle). Flight annunciator showed heading select, not VOR. I should have monitored intercept. In medium large transport aircraft this takes a constant awareness as the one course line in the HSI is hidden by the yoke and an effort to look around the yoke is required. To see the HSI display in all but the most forward seat position.

Title: FLT FAILED TO INTERCEPT ON COURSE RADIAL. REPORTER BELIEVES THIS WAS CAUSED IN SOME PART BY THE ACFT COCKPIT DESIGN.
Narrative: CLRED BY DEP TO FLY HDG 060 DEGS TO INTERCEPT 090 DEG R DALLAS 6. I THOUGHT I HAD SET VOR INTERCEPT ON THE FLT MGMNT PANEL (AUTOMATED COCKPIT). NEXT HEARD CENTER (AFTER FREQ CHANGE) SAY TURN RIGHT 100 DEGS TO INTERCEPT 090 DEG R DALLAS 6 DEP. I HAD GONE THROUGH THE RADIAL (NOT MORE THAN 5-10 MI DUE TO X ANGLE). FLT ANNUNCIATOR SHOWED HDG SELECT, NOT VOR. I SHOULD HAVE MONITORED INTERCEPT. IN MLG ACFT THIS TAKES A CONSTANT AWARENESS AS THE ONE COURSE LINE IN THE HSI IS HIDDEN BY THE YOKE AND AN EFFORT TO LOOK AROUND THE YOKE IS REQUIRED. TO SEE THE HSI DISPLAY IN ALL BUT THE MOST FORWARD SEAT POS.
