Narrative:

I and a private student were en route on a cross country training flight sbound along route 15 west of iad. Upon reaching our chkpoint at lake manassas, west of hef, I instructed the student to climb to 2100 ft and turn left 20 degrees to our next en route course. I then referred to a chart and studied our position. I was reading the chart and watching for traffic. I did not realize that my student had turned approximately 60 degrees left and was flying us straight for manassas class D airspace. By the time I realized the error, we were approximately 4 mi from hef at approximately 1900 ft. Conditions at the time were 4500 ft broken, 320 degrees, 20 KTS gusting to 25 KTS. Tailwind increased our ground speed to approximately 110 KTS after the left turn and we reached manassas airspace much faster than I anticipated. Normal cruise is approximately 75 mph. Upon realizing the error, I assumed control of the aircraft, turned right and departed the area southeast.

Title: FLT INSTRUCTOR AND PVT PLT ON XCOUNTRY TRAINING FLT BELIEVES THEY MAY HAVE POSSIBLY INADVERTENTLY FLOWN INTO THE HEF CLASS D AIRSPACE WHEN INSTRUCTOR BECAME DISTR LOOKING AT CHART.

Narrative: I AND A PVT STUDENT WERE ENRTE ON A XCOUNTRY TRAINING FLT SBOUND ALONG ROUTE 15 W OF IAD. UPON REACHING OUR CHKPOINT AT LAKE MANASSAS, W OF HEF, I INSTRUCTED THE STUDENT TO CLB TO 2100 FT AND TURN L 20 DEGS TO OUR NEXT ENRTE COURSE. I THEN REFERRED TO A CHART AND STUDIED OUR POS. I WAS READING THE CHART AND WATCHING FOR TFC. I DID NOT REALIZE THAT MY STUDENT HAD TURNED APPROX 60 DEGS L AND WAS FLYING US STRAIGHT FOR MANASSAS CLASS D AIRSPACE. BY THE TIME I REALIZED THE ERROR, WE WERE APPROX 4 MI FROM HEF AT APPROX 1900 FT. CONDITIONS AT THE TIME WERE 4500 FT BROKEN, 320 DEGS, 20 KTS GUSTING TO 25 KTS. TAILWIND INCREASED OUR GND SPD TO APPROX 110 KTS AFTER THE L TURN AND WE REACHED MANASSAS AIRSPACE MUCH FASTER THAN I ANTICIPATED. NORMAL CRUISE IS APPROX 75 MPH. UPON REALIZING THE ERROR, I ASSUMED CTL OF THE ACFT, TURNED R AND DEPARTED THE AREA SE.
