Narrative:

Approximately 2 mins after takeoff, the right engine fire light illuminated. We performed the engine fire in-flight emergency checklist which included firing the fire bottle into the engine. After the checklist was completed, the fire light remained illuminated. There was no visual indication of a fire, but we asked for crash fire rescue equipment upon landing as a precaution. We were then vectored for landing on runway 7R at mke. The flight proceeded normally from completion of the checklist. After landing, we requested the crash fire rescue equipment to check the engine for fire/smoke that we might not have seen. They reported no fire or smoke so we proceeded to parking. As I assumed, it was an indication problem. No fire or smoke damage was discovered on postflt. Also, at one point during the flight we were closer to waukesha airport than mke due to vectors around WX. However, I elected to continue to mke due to 2 reasons. One, the surface winds were 330 degrees at 18 KTS gusting to 25 which was a direct crosswind for waukesha's instrument runway 10. Second, mke has far superior crash fire rescue equipment compared to VE5 and I felt that was very important considering our possible engine fire.

Title: SMT CARGO FLC HAS ENG FIRE LIGHT ACTIVATE. AFTER EMER CHKLIST PROCS THE FIRE LIGHT REMAINED ILLUMINATED.

Narrative: APPROX 2 MINS AFTER TKOF, THE R ENG FIRE LIGHT ILLUMINATED. WE PERFORMED THE ENG FIRE INFLT EMER CHKLIST WHICH INCLUDED FIRING THE FIRE BOTTLE INTO THE ENG. AFTER THE CHKLIST WAS COMPLETED, THE FIRE LIGHT REMAINED ILLUMINATED. THERE WAS NO VISUAL INDICATION OF A FIRE, BUT WE ASKED FOR CFR UPON LNDG AS A PRECAUTION. WE WERE THEN VECTORED FOR LNDG ON RWY 7R AT MKE. THE FLT PROCEEDED NORMALLY FROM COMPLETION OF THE CHKLIST. AFTER LNDG, WE REQUESTED THE CFR TO CHK THE ENG FOR FIRE/SMOKE THAT WE MIGHT NOT HAVE SEEN. THEY RPTED NO FIRE OR SMOKE SO WE PROCEEDED TO PARKING. AS I ASSUMED, IT WAS AN INDICATION PROB. NO FIRE OR SMOKE DAMAGE WAS DISCOVERED ON POSTFLT. ALSO, AT ONE POINT DURING THE FLT WE WERE CLOSER TO WAUKESHA ARPT THAN MKE DUE TO VECTORS AROUND WX. HOWEVER, I ELECTED TO CONTINUE TO MKE DUE TO 2 REASONS. ONE, THE SURFACE WINDS WERE 330 DEGS AT 18 KTS GUSTING TO 25 WHICH WAS A DIRECT XWIND FOR WAUKESHA'S INST RWY 10. SECOND, MKE HAS FAR SUPERIOR CFR COMPARED TO VE5 AND I FELT THAT WAS VERY IMPORTANT CONSIDERING OUR POSSIBLE ENG FIRE.
