Narrative:

During unusual attitude recovery, student may have entered los angeles class B airspace. Noting our position near the water treatment plant, it occurred to me that we might have entered the 4000 ft area of the los angeles class B airspace. I don't think we did, but we would have been close if we didn't. Plan to start unusual altitude recoveries with greater distance from class B airspace so I'm positive there will be no airspace incursion. I think we were under the 8000-9000 ft floor, but I'm just not sure. I was having the student fly under the hood for a while to get disoriented. I was watching for traffic and airspace. I thought the pom VOR 175 degree radial was centered so it should have been ok, but VOR hadn't been checked before this particular flight.

Narrative: DURING UNUSUAL ATTITUDE RECOVERY, STUDENT MAY HAVE ENTERED LOS ANGELES CLASS B AIRSPACE. NOTING OUR POS NEAR THE WATER TREATMENT PLANT, IT OCCURRED TO ME THAT WE MIGHT HAVE ENTERED THE 4000 FT AREA OF THE LOS ANGELES CLASS B AIRSPACE. I DON'T THINK WE DID, BUT WE WOULD HAVE BEEN CLOSE IF WE DIDN'T. PLAN TO START UNUSUAL ALT RECOVERIES WITH GREATER DISTANCE FROM CLASS B AIRSPACE SO I'M POSITIVE THERE WILL BE NO AIRSPACE INCURSION. I THINK WE WERE UNDER THE 8000-9000 FT FLOOR, BUT I'M JUST NOT SURE. I WAS HAVING THE STUDENT FLY UNDER THE HOOD FOR A WHILE TO GET DISORIENTED. I WAS WATCHING FOR TFC AND AIRSPACE. I THOUGHT THE POM VOR 175 DEG RADIAL WAS CTRED SO IT SHOULD HAVE BEEN OK, BUT VOR HADN'T BEEN CHKED BEFORE THIS PARTICULAR FLT.
