Narrative:
On climb out from mco passing 1500 ft MSL, we received an RA on TCASII instructing us to climb at a greater rate. The TCASII indicated a target 300 ft below us. Departure control said they had nobody on radar. The RA lasted 1000-1500 ft of climb. We never saw another aircraft. We also turned 40 degrees left (heading 120 degrees) of assigned heading of 160 degrees during the RA maneuver along with a maximum power climb out until the RA disappeared. No further incident occurred and we continued to our destination. Departure control told us to contact the mco tower upon landing. We complied.
Original NASA ASRS Text
Title: ACR MLG TCASII RA ON UNKNOWN ACFT BELOW AFTER TKOF FROM MCO. ELONGATED RA COMMAND DURING CLB WITH INITIALLY SENSED NEAR COLLISION. FLC TURNS ACFT OFF ASSIGNED HEADING AS WELL AS CLB TO AVOID UNIDENTED TARGET.
Narrative: ON CLBOUT FROM MCO PASSING 1500 FT MSL, WE RECEIVED AN RA ON TCASII INSTRUCTING US TO CLB AT A GREATER RATE. THE TCASII INDICATED A TARGET 300 FT BELOW US. DEP CTL SAID THEY HAD NOBODY ON RADAR. THE RA LASTED 1000-1500 FT OF CLB. WE NEVER SAW ANOTHER ACFT. WE ALSO TURNED 40 DEGS L (HDG 120 DEGS) OF ASSIGNED HDG OF 160 DEGS DURING THE RA MANEUVER ALONG WITH A MAX PWR CLBOUT UNTIL THE RA DISAPPEARED. NO FURTHER INCIDENT OCCURRED AND WE CONTINUED TO OUR DEST. DEP CTL TOLD US TO CONTACT THE MCO TWR UPON LNDG. WE COMPLIED.
