Narrative:

Tower cleared us for takeoff runway 23, initial altitude of 4000 ft, with instructions to turn left to heading 170 degrees. WX reported as scattered clouds, 6 mi visibility with haze. As we passed approximately 300 ft AGL (approximately 1300 ft MSL), tower controller came on and said he needed a good rate of turn to 170 degree heading as he had traffic holding at 2500 ft (I believe he was at kanco, the IAF for ILS runway 5). As we passed 400 ft AGL, I turned aircraft into a 25 degree left bank maintaining takeoff flaps, maximum rated thrust, and V2 plus 10 speed. As I turned toward 170 degrees, I saw a hill/ridge ahead. I was not concerned about the safety of our position relative to the hill. (I later noted that the highest point on the hill was a tower 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 controller still seemed to be not satisfied with our turn as he had us turn further to 150 degrees because of the traffic. We could not tell where traffic was and never saw it. Shortly after, tower told us we were clear of traffic, turn right to 210 degree heading, contact departure. Tower controller clearly knew the holding traffic was out there, but he did not see fit to impart that information to us prior to our takeoff roll. Since, at 400 ft AGL, he was asking us to make our aircraft perform optimally, it would have helped to have that information 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 cleared us for takeoff.

Title: 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.
