Narrative:

On arrival to orl, the approach controller instructed us to maintain 2000 ft until established on the approach, and cleared us for the ILS runway 7 approach. He then advised us to contact the tower. While changing frequencys, and maintaining 2000 ft, the crew received a TCASII warning showing a target rapidly approaching their altitude. The PF called the TCASII alert and advised that the target was not in sight and immediately began the evasive maneuver commanded by the TCASII. The TCASII commanded a minimum 1800 FPM climb to avoid collision with the target that was now showing 300 ft below and decreasing in separation. The climb was continued until the RA ceased, which put the aircraft at 2500 ft MSL. A return to the assigned altitude was immediately initiated when the RA was cleared. During the evasive maneuver, the PNF was trying to contact the tower, but congestion on the frequency prevented him from doing so. When the PNF did make contact with the tower, he advised them of the RA and that we were returning to the last assigned altitude. The controller chastised the crew for deviating without clearance and climbing into class B airspace. She ordered us to return to 2000 ft, which we were already initiating. We explained the reason for the deviation, the RA, and were told that the aircraft was a helicopter, and was behind us. When we cleared the runway, the PNF requested and received the phone number to the control tower so as to clarify the situation. When the PNF contacted the tower, the controller that handled our arrival again began to chastise our actions, even after explaining TCASII procedures. She said that we came within 1/8 of 1 mi from hitting another aircraft (which did not show on TCASII). There was no resolution with the tower. The PNF requested and received the phone number to orlando approach control. Contacting approach control, the PNF asked if our excursion had endangered any other aircraft, or if we had created any problems for their airspace, as was reported. The controller said no. When asked about the second aircraft that we repeatedly almost hit during our deviation, he said that the aircraft she was referring to was actually behind us and moving in the opposite direction at the time of our RA. He said he understood and acknowledged the pilot's responsibility to follow RA instructions to avoid collisions. He volunteered that when the tower controller called him that she sounded 'over dramatic' with the situation.

Title: BE40 EXPERIENCED TCASII-TCAD RA ON APCH TO ORL AND ENTERED CLASS B.

Narrative: ON ARR TO ORL, THE APCH CTLR INSTRUCTED US TO MAINTAIN 2000 FT UNTIL ESTABLISHED ON THE APCH, AND CLRED US FOR THE ILS RWY 7 APCH. HE THEN ADVISED US TO CONTACT THE TWR. WHILE CHANGING FREQS, AND MAINTAINING 2000 FT, THE CREW RECEIVED A TCASII WARNING SHOWING A TARGET RAPIDLY APCHING THEIR ALT. THE PF CALLED THE TCASII ALERT AND ADVISED THAT THE TARGET WAS NOT IN SIGHT AND IMMEDIATELY BEGAN THE EVASIVE MANEUVER COMMANDED BY THE TCASII. THE TCASII COMMANDED A MINIMUM 1800 FPM CLB TO AVOID COLLISION WITH THE TARGET THAT WAS NOW SHOWING 300 FT BELOW AND DECREASING IN SEPARATION. THE CLB WAS CONTINUED UNTIL THE RA CEASED, WHICH PUT THE ACFT AT 2500 FT MSL. A RETURN TO THE ASSIGNED ALT WAS IMMEDIATELY INITIATED WHEN THE RA WAS CLRED. DURING THE EVASIVE MANEUVER, THE PNF WAS TRYING TO CONTACT THE TWR, BUT CONGESTION ON THE FREQ PREVENTED HIM FROM DOING SO. WHEN THE PNF DID MAKE CONTACT WITH THE TWR, HE ADVISED THEM OF THE RA AND THAT WE WERE RETURNING TO THE LAST ASSIGNED ALT. THE CTLR CHASTISED THE CREW FOR DEVIATING WITHOUT CLRNC AND CLBING INTO CLASS B AIRSPACE. SHE ORDERED US TO RETURN TO 2000 FT, WHICH WE WERE ALREADY INITIATING. WE EXPLAINED THE REASON FOR THE DEV, THE RA, AND WERE TOLD THAT THE ACFT WAS A HELI, AND WAS BEHIND US. WHEN WE CLRED THE RWY, THE PNF REQUESTED AND RECEIVED THE PHONE NUMBER TO THE CTL TWR SO AS TO CLARIFY THE SIT. WHEN THE PNF CONTACTED THE TWR, THE CTLR THAT HANDLED OUR ARR AGAIN BEGAN TO CHASTISE OUR ACTIONS, EVEN AFTER EXPLAINING TCASII PROCS. SHE SAID THAT WE CAME WITHIN 1/8 OF 1 MI FROM HITTING ANOTHER ACFT (WHICH DID NOT SHOW ON TCASII). THERE WAS NO RESOLUTION WITH THE TWR. THE PNF REQUESTED AND RECEIVED THE PHONE NUMBER TO ORLANDO APCH CTL. CONTACTING APCH CTL, THE PNF ASKED IF OUR EXCURSION HAD ENDANGERED ANY OTHER ACFT, OR IF WE HAD CREATED ANY PROBS FOR THEIR AIRSPACE, AS WAS RPTED. THE CTLR SAID NO. WHEN ASKED ABOUT THE SECOND ACFT THAT WE REPEATEDLY ALMOST HIT DURING OUR DEV, HE SAID THAT THE ACFT SHE WAS REFERRING TO WAS ACTUALLY BEHIND US AND MOVING IN THE OPPOSITE DIRECTION AT THE TIME OF OUR RA. HE SAID HE UNDERSTOOD AND ACKNOWLEDGED THE PLT'S RESPONSIBILITY TO FOLLOW RA INSTRUCTIONS TO AVOID COLLISIONS. HE VOLUNTEERED THAT WHEN THE TWR CTLR CALLED HIM THAT SHE SOUNDED 'OVER DRAMATIC' WITH THE SIT.
