Narrative:

Waited for ATC release for IFR departure from agc. Was released and cleared for takeoff. During climb over departure end of runway, was cleared to departure. Contacted departure control 'out of 2100, climbing to 3000'.' there was a squeal of numerous xmissions, which ended with 'stop your climb at 2500.' this instruction was repeated prefaced with our tail #. Level off was at 2600', and we saw a flight check small transport fly over in a right turn at 3000'. If we had been doing a better rate of climb, it probably could have been a collision. Flight check aircraft was VFR and requested IFR to acy. Opinion would say if flight check aircraft are in area, they should be on IFR (WX 1100' and 3 mi) flight plan. Also should be in better coordination with departure control. Also, I disagree with aircraft operating in opp direction of traffic flow in use. (This aircraft was on ILS to when traffic was on runway 28.

Original NASA ASRS Text

Title: NMAC. ATX ACFT MISSES GOVT ACFT ON APCH PATH TO OPPOSITE END OF DEP RWY. DEP CTLR ALERTS ATX FLT CREW.

Narrative: WAITED FOR ATC RELEASE FOR IFR DEP FROM AGC. WAS RELEASED AND CLRED FOR TKOF. DURING CLB OVER DEP END OF RWY, WAS CLRED TO DEP. CONTACTED DEP CTL 'OUT OF 2100, CLBING TO 3000'.' THERE WAS A SQUEAL OF NUMEROUS XMISSIONS, WHICH ENDED WITH 'STOP YOUR CLB AT 2500.' THIS INSTRUCTION WAS REPEATED PREFACED WITH OUR TAIL #. LEVEL OFF WAS AT 2600', AND WE SAW A FLT CHK SMT FLY OVER IN A RIGHT TURN AT 3000'. IF WE HAD BEEN DOING A BETTER RATE OF CLB, IT PROBABLY COULD HAVE BEEN A COLLISION. FLT CHK ACFT WAS VFR AND REQUESTED IFR TO ACY. OPINION WOULD SAY IF FLT CHK ACFT ARE IN AREA, THEY SHOULD BE ON IFR (WX 1100' AND 3 MI) FLT PLAN. ALSO SHOULD BE IN BETTER COORD WITH DEP CTL. ALSO, I DISAGREE WITH ACFT OPERATING IN OPP DIRECTION OF TFC FLOW IN USE. (THIS ACFT WAS ON ILS TO WHEN TFC WAS ON RWY 28.
