AN ACR MLG PLT BECAME CONCERNED THAT HE DID NOT KNOW AS MUCH ABOUT THE LCL TERRAIN AT CRW AS HE WOULD HAVE LIKED.

Narrative

TWR CLRED US FOR TKOF RWY 23; INITIAL ALT OF 4000 FT; WITH INSTRUCTIONS TO TURN L TO HDG 170 DEGS. WX RPTED AS SCATTERED CLOUDS; 6 MI VISIBILITY WITH HAZE. AS WE PASSED APPROX 300 FT AGL (APPROX 1300 FT MSL); TWR CTLR CAME ON AND SAID HE NEEDED A GOOD RATE OF TURN TO 170 DEG HDG AS HE HAD TFC HOLDING AT 2500 FT (I BELIEVE HE WAS AT KANCO; THE IAF FOR ILS RWY 5). AS WE PASSED 400 FT AGL; I TURNED ACFT INTO A 25 DEG L BANK MAINTAINING TKOF FLAPS; MAX RATED THRUST; AND V2 PLUS 10 SPD. AS I TURNED TOWARD 170 DEGS; I SAW A HILL/RIDGE AHEAD. I WAS NOT CONCERNED ABOUT THE SAFETY OF OUR POS RELATIVE TO THE HILL. (I LATER NOTED THAT THE HIGHEST POINT ON THE HILL WAS A TWR AT 1297 FT MSL.) AS WE FIRST LOOKED AT THE HILL; RADIO ALTIMETER WAS AT ABOUT 700 FT AGL AND WE MAINTAINED GOOD VISUAL ON THE HILL AND HAD A POSITIVE GRADIENT RELATIVE TO THE TERRAIN AT ALL TIMES. THE CTLR STILL SEEMED TO BE NOT SATISFIED WITH OUR TURN AS HE HAD US TURN FURTHER TO 150 DEGS BECAUSE OF THE TFC. WE COULD NOT TELL WHERE TFC WAS AND NEVER SAW IT. SHORTLY AFTER; TWR TOLD US WE WERE CLR OF TFC; TURN R TO 210 DEG HDG; CONTACT DEP. TWR CTLR CLEARLY KNEW THE HOLDING TFC WAS OUT THERE; BUT HE DID NOT SEE FIT TO IMPART THAT INFO TO US PRIOR TO OUR TKOF ROLL. SINCE; AT 400 FT AGL; HE WAS ASKING US TO MAKE OUR ACFT PERFORM OPTIMALLY; IT WOULD HAVE HELPED TO HAVE THAT INFO EARLY. I WOULD HOPE MY SITUATIONAL AWARENESS OF WHAT WAS OUT THERE WOULD HAVE BEEN MUCH BETTER HAD I KNOWN OF HIS REQUIREMENTS BEFORE HE CLRED US FOR TKOF.
