Narrative:

WX clear VMC, we were talking with a busy miami approach control and were approximately 15 NM northeast of mia international descending out of 10000 ft MSL. There were several other aircraft also inbound to mia, as this is a busy time. We were given a vector to fly heading of approximately 150 degrees to follow traffic. At that time we encountered moderate wake turbulence for approximately 5-10 seconds. At no time was control of the aircraft lost, and all it did was startle the passenger and flight attendant. I then looked over and saw a B767 approximately 10 NM ahead, and it would appear that we had flown through its wake. Being so far ahead it is hard to visualize an aircraft's wake, as opposed to being right behind on a straight in approach. I informed approach of the occurrence, and we stayed high on the subsequent approach to avoid further encounters. This very incident has happened to me at least 4 other times at the same place in the past. Callback conversation with reporter revealed the following: reporter was most anxious to participate in the wake turbulence incident callback questionnaire. He was very much bothered by the 40 degree roll and the 200 ft loss of altitude. He would very much like the TRACON controllers to be trained in wake turbulence avoidance. Felt they could recognize the high possibility of wake development by the wind condition and the aircraft being flown in the area. Reporter feels ATC could do more in recognizing the potential for wake turbulence. Also, he wants ATC controllers to be onboard aircraft when they encounter wake turbulence so they will know what it is a flight crew member feels when an aircraft encounters the wake.

Title: WAKE TURB ENCOUNTER.

Narrative: WX CLR VMC, WE WERE TALKING WITH A BUSY MIAMI APCH CTL AND WERE APPROX 15 NM NE OF MIA INTL DSNDING OUT OF 10000 FT MSL. THERE WERE SEVERAL OTHER ACFT ALSO INBOUND TO MIA, AS THIS IS A BUSY TIME. WE WERE GIVEN A VECTOR TO FLY HDG OF APPROX 150 DEGS TO FOLLOW TFC. AT THAT TIME WE ENCOUNTERED MODERATE WAKE TURB FOR APPROX 5-10 SECONDS. AT NO TIME WAS CTL OF THE ACFT LOST, AND ALL IT DID WAS STARTLE THE PAX AND FLT ATTENDANT. I THEN LOOKED OVER AND SAW A B767 APPROX 10 NM AHEAD, AND IT WOULD APPEAR THAT WE HAD FLOWN THROUGH ITS WAKE. BEING SO FAR AHEAD IT IS HARD TO VISUALIZE AN ACFT'S WAKE, AS OPPOSED TO BEING RIGHT BEHIND ON A STRAIGHT IN APCH. I INFORMED APCH OF THE OCCURRENCE, AND WE STAYED HIGH ON THE SUBSEQUENT APCH TO AVOID FURTHER ENCOUNTERS. THIS VERY INCIDENT HAS HAPPENED TO ME AT LEAST 4 OTHER TIMES AT THE SAME PLACE IN THE PAST. CALLBACK CONVERSATION WITH REPORTER REVEALED THE FOLLOWING: RPTR WAS MOST ANXIOUS TO PARTICIPATE IN THE WAKE TURB INCIDENT CALLBACK QUESTIONNAIRE. HE WAS VERY MUCH BOTHERED BY THE 40 DEG ROLL AND THE 200 FT LOSS OF ALT. HE WOULD VERY MUCH LIKE THE TRACON CTLRS TO BE TRAINED IN WAKE TURB AVOIDANCE. FELT THEY COULD RECOGNIZE THE HIGH POSSIBILITY OF WAKE DEVELOPMENT BY THE WIND CONDITION AND THE ACFT BEING FLOWN IN THE AREA. RPTR FEELS ATC COULD DO MORE IN RECOGNIZING THE POTENTIAL FOR WAKE TURB. ALSO, HE WANTS ATC CTLRS TO BE ONBOARD ACFT WHEN THEY ENCOUNTER WAKE TURB SO THEY WILL KNOW WHAT IT IS A FLC MEMBER FEELS WHEN AN ACFT ENCOUNTERS THE WAKE.
