Narrative:
Handoff from msp departure control to ZMP frequency 134.85 was requested to increase airspeed to 300 KTS above 10000 ft. I advised unable due to turbulence 250 KTS maximum turbulence speed. We requested a heading change for avoidance of WX. We were only allowed 10 degrees change. We requested higher than 17000 ft avoid more WX and were held down to lower altitude, while other aircraft were cleared to higher altitudes. We later were cleared to FL210, still in the thunderstorm tops, requested higher and was given a turn directly into the storms for our climb. We advised unable. I reported a PIREP of moderate turbulence and advised the center not to oppose our every request. She explained that we should advise her of our situation. I thought we had with our PIREP and 250 KTS saying it was our maximum turbulent air penetration speed. (This ATC controller should understand the restr and limitations of transport aircraft. Spacing is important to ATC for safety. I understand that, the WX environment causes problems for us all.)
Original NASA ASRS Text
Title: CAPT OF AN LGT BECAME UPSET WITH ARTCC CTLR SINCE HE COULD NOT OBTAIN HIGHER ALTS TO GET OUT OF TURB OF TSTMS.
Narrative: HDOF FROM MSP DEP CTL TO ZMP FREQ 134.85 WAS REQUESTED TO INCREASE AIRSPD TO 300 KTS ABOVE 10000 FT. I ADVISED UNABLE DUE TO TURB 250 KTS MAXIMUM TURB SPD. WE REQUESTED A HDG CHANGE FOR AVOIDANCE OF WX. WE WERE ONLY ALLOWED 10 DEGS CHANGE. WE REQUESTED HIGHER THAN 17000 FT AVOID MORE WX AND WERE HELD DOWN TO LOWER ALT, WHILE OTHER ACFT WERE CLRED TO HIGHER ALTS. WE LATER WERE CLRED TO FL210, STILL IN THE TSTM TOPS, REQUESTED HIGHER AND WAS GIVEN A TURN DIRECTLY INTO THE STORMS FOR OUR CLB. WE ADVISED UNABLE. I RPTED A PIREP OF MODERATE TURB AND ADVISED THE CTR NOT TO OPPOSE OUR EVERY REQUEST. SHE EXPLAINED THAT WE SHOULD ADVISE HER OF OUR SIT. I THOUGHT WE HAD WITH OUR PIREP AND 250 KTS SAYING IT WAS OUR MAXIMUM TURBULENT AIR PENETRATION SPD. (THIS ATC CTLR SHOULD UNDERSTAND THE RESTR AND LIMITATIONS OF TRANSPORT ACFT. SPACING IS IMPORTANT TO ATC FOR SAFETY. I UNDERSTAND THAT, THE WX ENVIRONMENT CAUSES PROBS FOR US ALL.)
