Narrative:

As the chief instrument and I (CFI) turned downwind, the tower asked us to make a tight pattern for runway 15R. My downwind leg was a little wide so I tightened the pattern enough to fly my normal downwind track. From the right seat in a right pattern, I could easily see a jet rolling down runway 25. As the jet rotated, I noticed that or flight paths would intersect. I assumed that the jet would cross beneath me, but it would still be pretty darn close. Then I thought 'oh no, I should have tightened my downwind leg some more for separation.' as the jet's climb altitude increased, I felt like the target of an intercept missile and took evasive action. Hoping that the jet would maintain runway heading to at least 1000 ft, I turned left (away from the airport) and initiated a shallow descent. I felt that I was doing that right thing if ATC was unaware of the situation. But what if ATC had already made provisions for separation? What if the jet was instructed to make a low altitude left turn in order to avoid me? Within moments after deviating, the chief instrument took over the controls and turned us back to downwind. I had no intention of fighting over the controls with him, but I was able to point out the jet as it passed slightly in front of us and overhead. After landing, the chief pilot asked ground control if the jet had visual contact with us. The controller said, 'uh, we will have to check the tape.' although he was just asking out of curiosity, I do not believe that we were in sight. The jet was fling directly into the sun and had a very high pitch attitude. I do not know if tower normally allows jets to takeoff of runway 7/25 while another airplane is approaching the extended centerline. Whatever the case, I believe that the corrective action would have been to hold the jet for another 8-10 seconds in order for me to clear the extended centerline of the takeoff runway.

Title: C172 TRNG FLC INITIATE EVASIVE MANEUVER IN RWY 32R TFC PATTERN TO AVOID CONFLICTING DEPING RWY 25 CORPORATE JET AT SBA.

Narrative: AS THE CHIEF INSTR AND I (CFI) TURNED DOWNWIND, THE TWR ASKED US TO MAKE A TIGHT PATTERN FOR RWY 15R. MY DOWNWIND LEG WAS A LITTLE WIDE SO I TIGHTENED THE PATTERN ENOUGH TO FLY MY NORMAL DOWNWIND TRACK. FROM THE RIGHT SEAT IN A RIGHT PATTERN, I COULD EASILY SEE A JET ROLLING DOWN RWY 25. AS THE JET ROTATED, I NOTICED THAT OR FLT PATHS WOULD INTERSECT. I ASSUMED THAT THE JET WOULD CROSS BENEATH ME, BUT IT WOULD STILL BE PRETTY DARN CLOSE. THEN I THOUGHT 'OH NO, I SHOULD HAVE TIGHTENED MY DOWNWIND LEG SOME MORE FOR SEPARATION.' AS THE JET'S CLIMB ALT INCREASED, I FELT LIKE THE TARGET OF AN INTERCEPT MISSILE AND TOOK EVASIVE ACTION. HOPING THAT THE JET WOULD MAINTAIN RWY HEADING TO AT LEAST 1000 FT, I TURNED LEFT (AWAY FROM THE ARPT) AND INITIATED A SHALLOW DSCNT. I FELT THAT I WAS DOING THAT RIGHT THING IF ATC WAS UNAWARE OF THE SIT. BUT WHAT IF ATC HAD ALREADY MADE PROVISIONS FOR SEPARATION? WHAT IF THE JET WAS INSTRUCTED TO MAKE A LOW ALT LEFT TURN IN ORDER TO AVOID ME? WITHIN MOMENTS AFTER DEVIATING, THE CHIEF INSTR TOOK OVER THE CTLS AND TURNED US BACK TO DOWNWIND. I HAD NO INTENTION OF FIGHTING OVER THE CTLS WITH HIM, BUT I WAS ABLE TO POINT OUT THE JET AS IT PASSED SLIGHTLY IN FRONT OF US AND OVERHEAD. AFTER LNDG, THE CHIEF PLT ASKED GND CTL IF THE JET HAD VISUAL CONTACT WITH US. THE CTLR SAID, 'UH, WE WILL HAVE TO CHECK THE TAPE.' ALTHOUGH HE WAS JUST ASKING OUT OF CURIOSITY, I DO NOT BELIEVE THAT WE WERE IN SIGHT. THE JET WAS FLING DIRECTLY INTO THE SUN AND HAD A VERY HIGH PITCH ATTITUDE. I DO NOT KNOW IF TWR NORMALLY ALLOWS JETS TO TKOF OF RWY 7/25 WHILE ANOTHER AIRPLANE IS APCHING THE EXTENDED CENTERLINE. WHATEVER THE CASE, I BELIEVE THAT THE CORRECTIVE ACTION WOULD HAVE BEEN TO HOLD THE JET FOR ANOTHER 8-10 SECS IN ORDER FOR ME TO CLR THE EXTENDED CENTERLINE OF THE TKOF RWY.
