Narrative:
We were given 5000 ft MSL as initial clearance altitude. Upon taxi instructions, we were changed from runway 28 to runway 22, which are crossing runways. After a short taxi, 2500 ft was given as our initial altitude at takeoff clearance. After breaking ground, tower instructed 2000 ft to be maintained as commercial traffic was climbing on a 180 degree turn off runway 28. This traffic came into view at 2 O'clock with uncomfortable range for commercial traffic in a TCA. We called traffic in sight and further climb was given. It is our opinion that sufficient clearance was maintained and tower gave no indication of a conflict. I fail to understand the initial altitudes below 5000 ft, especially in large turbojet aircraft and congested TCA's.
Original NASA ASRS Text
Title: FLT CREW OF MLG GIVEN 5000' FOR INITIAL LEVEL OFF RECEIVED AMENDED CLRNC 2000'.
Narrative: WE WERE GIVEN 5000 FT MSL AS INITIAL CLRNC ALT. UPON TAXI INSTRUCTIONS, WE WERE CHANGED FROM RWY 28 TO RWY 22, WHICH ARE XING RWYS. AFTER A SHORT TAXI, 2500 FT WAS GIVEN AS OUR INITIAL ALT AT TKOF CLRNC. AFTER BREAKING GND, TWR INSTRUCTED 2000 FT TO BE MAINTAINED AS COMMERCIAL TFC WAS CLBING ON A 180 DEG TURN OFF RWY 28. THIS TFC CAME INTO VIEW AT 2 O'CLOCK WITH UNCOMFORTABLE RANGE FOR COMMERCIAL TFC IN A TCA. WE CALLED TFC IN SIGHT AND FURTHER CLB WAS GIVEN. IT IS OUR OPINION THAT SUFFICIENT CLRNC WAS MAINTAINED AND TWR GAVE NO INDICATION OF A CONFLICT. I FAIL TO UNDERSTAND THE INITIAL ALTS BELOW 5000 FT, ESPECIALLY IN LARGE TURBOJET ACFT AND CONGESTED TCA'S.
