Narrative:

I was on a training flight with a student pilot. This was her 2ND flight and the student was flying. We were returning to the airport from northwest and were advised to enter from the north; report 2 mi north of the field and enter left downwind for runway 8. Our aircraft does not have tis or traffic alert system; so extra care must be used to scan for traffic. We were approximately 2 mi northwest of the field heading southeast when a twin cessna appeared from our 10 O'clock position flying sbound; making a right turn in front of us to join left downwind for runway 8 at fxe. The traffic appeared to be as close as 100 ft in front of us and fast moving to our right. When I saw the traffic I did take over controls and pulled up with a left turn avoiding the turning traffic (but got a light hit of his wake turbulence) and reported the near collision with the twin to the tower. We did not get a particular acknowledgement to our report at this point. We were then told to follow the twin and were cleared to land on runway 8. Once on the ground I did receive the tail number to the other aircraft. The rest of the flight went uneventfully. I found that there can never be enough vigilance maintained arriving to and departing from airports; especially an airport such as fxe; which is in the midst of several airspaces and other airports. This makes the space crowded and causes all traffic to use mostly same quadrants to enter and exit the traffic pattern. Also; the mix of traffic is quite broad; from student pilots to cpr jets and private flts along with helicopter traffic all blended together.

Title: C172 VFR ARR TO FXE EXPERIENCED NMAC WITH UNREPORTED TFC ENTERING SAME DOWNWIND FOR RWY 8.

Narrative: I WAS ON A TRAINING FLT WITH A STUDENT PLT. THIS WAS HER 2ND FLT AND THE STUDENT WAS FLYING. WE WERE RETURNING TO THE ARPT FROM NW AND WERE ADVISED TO ENTER FROM THE N; RPT 2 MI N OF THE FIELD AND ENTER L DOWNWIND FOR RWY 8. OUR ACFT DOES NOT HAVE TIS OR TFC ALERT SYS; SO EXTRA CARE MUST BE USED TO SCAN FOR TFC. WE WERE APPROX 2 MI NW OF THE FIELD HDG SE WHEN A TWIN CESSNA APPEARED FROM OUR 10 O'CLOCK POS FLYING SBOUND; MAKING A R TURN IN FRONT OF US TO JOIN L DOWNWIND FOR RWY 8 AT FXE. THE TFC APPEARED TO BE AS CLOSE AS 100 FT IN FRONT OF US AND FAST MOVING TO OUR R. WHEN I SAW THE TFC I DID TAKE OVER CTLS AND PULLED UP WITH A L TURN AVOIDING THE TURNING TFC (BUT GOT A LIGHT HIT OF HIS WAKE TURB) AND RPTED THE NEAR COLLISION WITH THE TWIN TO THE TWR. WE DID NOT GET A PARTICULAR ACKNOWLEDGEMENT TO OUR RPT AT THIS POINT. WE WERE THEN TOLD TO FOLLOW THE TWIN AND WERE CLRED TO LAND ON RWY 8. ONCE ON THE GND I DID RECEIVE THE TAIL NUMBER TO THE OTHER ACFT. THE REST OF THE FLT WENT UNEVENTFULLY. I FOUND THAT THERE CAN NEVER BE ENOUGH VIGILANCE MAINTAINED ARRIVING TO AND DEPARTING FROM ARPTS; ESPECIALLY AN ARPT SUCH AS FXE; WHICH IS IN THE MIDST OF SEVERAL AIRSPACES AND OTHER ARPTS. THIS MAKES THE SPACE CROWDED AND CAUSES ALL TFC TO USE MOSTLY SAME QUADRANTS TO ENTER AND EXIT THE TFC PATTERN. ALSO; THE MIX OF TFC IS QUITE BROAD; FROM STUDENT PLTS TO CPR JETS AND PVT FLTS ALONG WITH HELI TFC ALL BLENDED TOGETHER.
