Narrative:
On departure from singapore seletar airport; we were cleared for takeoff runway 21 and to climb runway heading. Normal takeoff clearance calls for a right turn after takeoff; to remain within the seletar control zone. There were 2 light aircraft in pattern; and ATC was coordinating the spacing. After takeoff at 1500 ft; the PF called for flaps up. This is contrary to our normal procedure for this runway. Just at that point ATC instructed us to make a right turn for the downwind leg and to remain with the seletar control zone. As our airspeed increased; I could see our current turn radius was not going to keep us within the control zone and I instructed the PF to tighten the turn. He then made a very minor correction and increased bank to approximately 30 degrees. At this point ATC again instructed us to remain within the seletar control zone and again I told the PF he needed to tighten the turn or we would not remain within our area. He made no further correction and allowed the airspeed to increase to 250 KTS. At this speed our turn radius was so big; we ended up flying north of the military control tower of the airport to the north and actually over its runway at 2500 ft and 250 KTS. When I informed the other pilot of what he had just done; he said he didn't care.
Original NASA ASRS Text
Title: GULFSTREAM IV FLT CREW ON DEP FROM WSSL (SELETAR; SINGAPORE) IS ISSUED CLRNC TO REMAIN IN SELETAR CTL ZONE.
Narrative: ON DEP FROM SINGAPORE SELETAR ARPT; WE WERE CLRED FOR TKOF RWY 21 AND TO CLB RWY HDG. NORMAL TKOF CLRNC CALLS FOR A R TURN AFTER TKOF; TO REMAIN WITHIN THE SELETAR CTL ZONE. THERE WERE 2 LIGHT ACFT IN PATTERN; AND ATC WAS COORDINATING THE SPACING. AFTER TKOF AT 1500 FT; THE PF CALLED FOR FLAPS UP. THIS IS CONTRARY TO OUR NORMAL PROC FOR THIS RWY. JUST AT THAT POINT ATC INSTRUCTED US TO MAKE A R TURN FOR THE DOWNWIND LEG AND TO REMAIN WITH THE SELETAR CTL ZONE. AS OUR AIRSPD INCREASED; I COULD SEE OUR CURRENT TURN RADIUS WAS NOT GOING TO KEEP US WITHIN THE CTL ZONE AND I INSTRUCTED THE PF TO TIGHTEN THE TURN. HE THEN MADE A VERY MINOR CORRECTION AND INCREASED BANK TO APPROX 30 DEGS. AT THIS POINT ATC AGAIN INSTRUCTED US TO REMAIN WITHIN THE SELETAR CTL ZONE AND AGAIN I TOLD THE PF HE NEEDED TO TIGHTEN THE TURN OR WE WOULD NOT REMAIN WITHIN OUR AREA. HE MADE NO FURTHER CORRECTION AND ALLOWED THE AIRSPD TO INCREASE TO 250 KTS. AT THIS SPD OUR TURN RADIUS WAS SO BIG; WE ENDED UP FLYING N OF THE MIL CTL TWR OF THE ARPT TO THE N AND ACTUALLY OVER ITS RWY AT 2500 FT AND 250 KTS. WHEN I INFORMED THE OTHER PLT OF WHAT HE HAD JUST DONE; HE SAID HE DIDN'T CARE.
