Narrative:

This was a training flight (BFR) that was being conducted by me. My student, a private-instrument rated pilot was flying the airplane on the left side. I was seated on the right. We departed runway 23 at bedford with the intent to head towards our practice area northwest of the field 12 NM away. We made a normal takeoff and climb out to the practice area. Visibility was good at the time, although we were flying into the sun. As we continued our climb out through 2500 ft (estimated), my student observed traffic off of our left side. My student took immediate action turning and climbing to the right. The dash 8 aircraft turned away and to their right. During our climb out my student and I had our attention outside the airplane. However, because we were climbing and the dash 8 was descending at high speed my student was unable to see the other aircraft until it was in close proximity. My student's actions were immediate and deliberate and we made a steep bank away from the traffic. At the closest point I estimate our distance to be 500 ft from the other aircraft. The dash 8 speed at the time has been estimated by me to be in excess of 150 KTS. Our speed at the time was between 75 KTS and 80 KTS. No TA was noted by me to have been issued to us by the tower. We were unaware of the traffic conflict until the point when we saw and avoided the traffic. In my opinion, there was no alternative actions or precautions that my flight could have taken, or I could have taken to avoid the situation. I feel that despite our efforts to scan for traffic, because of the climb attitude we were in, it was unrealistic to expect us to see the traffic any sooner, especially with the dash 8 descending nose low at high velocity.

Title: PA28 INSTRUCTOR AND PLT WERE REQUIRED TO TAKE EVASIVE ACTION DEPARTING BED ARPT.

Narrative: THIS WAS A TRAINING FLT (BFR) THAT WAS BEING CONDUCTED BY ME. MY STUDENT, A PVT-INST RATED PLT WAS FLYING THE AIRPLANE ON THE L SIDE. I WAS SEATED ON THE R. WE DEPARTED RWY 23 AT BEDFORD WITH THE INTENT TO HEAD TOWARDS OUR PRACTICE AREA NW OF THE FIELD 12 NM AWAY. WE MADE A NORMAL TKOF AND CLBOUT TO THE PRACTICE AREA. VISIBILITY WAS GOOD AT THE TIME, ALTHOUGH WE WERE FLYING INTO THE SUN. AS WE CONTINUED OUR CLBOUT THROUGH 2500 FT (ESTIMATED), MY STUDENT OBSERVED TFC OFF OF OUR L SIDE. MY STUDENT TOOK IMMEDIATE ACTION TURNING AND CLBING TO THE R. THE DASH 8 ACFT TURNED AWAY AND TO THEIR R. DURING OUR CLBOUT MY STUDENT AND I HAD OUR ATTN OUTSIDE THE AIRPLANE. HOWEVER, BECAUSE WE WERE CLBING AND THE DASH 8 WAS DSNDING AT HIGH SPD MY STUDENT WAS UNABLE TO SEE THE OTHER ACFT UNTIL IT WAS IN CLOSE PROX. MY STUDENT'S ACTIONS WERE IMMEDIATE AND DELIBERATE AND WE MADE A STEEP BANK AWAY FROM THE TFC. AT THE CLOSEST POINT I ESTIMATE OUR DISTANCE TO BE 500 FT FROM THE OTHER ACFT. THE DASH 8 SPD AT THE TIME HAS BEEN ESTIMATED BY ME TO BE IN EXCESS OF 150 KTS. OUR SPD AT THE TIME WAS BTWN 75 KTS AND 80 KTS. NO TA WAS NOTED BY ME TO HAVE BEEN ISSUED TO US BY THE TWR. WE WERE UNAWARE OF THE TFC CONFLICT UNTIL THE POINT WHEN WE SAW AND AVOIDED THE TFC. IN MY OPINION, THERE WAS NO ALTERNATIVE ACTIONS OR PRECAUTIONS THAT MY FLT COULD HAVE TAKEN, OR I COULD HAVE TAKEN TO AVOID THE SIT. I FEEL THAT DESPITE OUR EFFORTS TO SCAN FOR TFC, BECAUSE OF THE CLB ATTITUDE WE WERE IN, IT WAS UNREALISTIC TO EXPECT US TO SEE THE TFC ANY SOONER, ESPECIALLY WITH THE DASH 8 DSNDING NOSE LOW AT HIGH VELOCITY.
