Narrative:

Briefed IFR departure as a heading until 4 DME, right turn to 070 degrees, cross a radial (280 dgs) at or above 4000' and below 7000'. After takeoff, raised gear, called departure control. First officer called for, '1/2 climb rate, flaps up, climb power,' and departure control said, 'turn left at 2 DME to 095 degrees, intercept ? Radio off of ? VOR and climb to ? Altitude, ' and to then proceed to another VOR and then as filed. At XA30 in the morning I wasn't in the right mood and just told him we would turn to 095 degrees and call him back. I thought the ATC system went through a communication/instruction purge a few yrs ago to avoid all those changes at a critical phase of flight. If not, they need to. Yes, I probably could have started taking notes at 1000', but is it safe? Not in my mind.

Original NASA ASRS Text

Title: FLT CREW OF ACR MLG OBJECTS TO AMENDED CLRNC JUST AFTER TKOF.

Narrative: BRIEFED IFR DEP AS A HDG UNTIL 4 DME, RIGHT TURN TO 070 DEGS, CROSS A RADIAL (280 DGS) AT OR ABOVE 4000' AND BELOW 7000'. AFTER TKOF, RAISED GEAR, CALLED DEP CTL. F/O CALLED FOR, '1/2 CLB RATE, FLAPS UP, CLB PWR,' AND DEP CTL SAID, 'TURN LEFT AT 2 DME TO 095 DEGS, INTERCEPT ? RADIO OFF OF ? VOR AND CLB TO ? ALT, ' AND TO THEN PROCEED TO ANOTHER VOR AND THEN AS FILED. AT XA30 IN THE MORNING I WASN'T IN THE RIGHT MOOD AND JUST TOLD HIM WE WOULD TURN TO 095 DEGS AND CALL HIM BACK. I THOUGHT THE ATC SYS WENT THROUGH A COM/INSTRUCTION PURGE A FEW YRS AGO TO AVOID ALL THOSE CHANGES AT A CRITICAL PHASE OF FLT. IF NOT, THEY NEED TO. YES, I PROBABLY COULD HAVE STARTED TAKING NOTES AT 1000', BUT IS IT SAFE? NOT IN MY MIND.
