Narrative:

Takeoff runway 27 memphis international. Latest ATIS gave winds of 140 degrees/6 KTS, low level windshear alert in effect. No obvious windshear present to aircrew. Cleared for takeoff. Once airborne at approximately 1000 ft, tower was heard advising next aircraft for runway 27 that winds were 90 degrees 12 KTS, which are beyond maximum tailwind for B727. Suspect winds were observed increasing to out of limits as that aircraft was preparing to take runway. My aircraft was not advised of any winds near or out of limits. Takeoff was normal in all respects, with no noticeable wind effect upon aircraft. Supplemental information from acn 409641: on pre-departure briefing, discussed windshear probability, and given light winds and no convective activity in vicinity of airport, we felt it was not a factor, but would remain alert for any changes. To avoid a similar occurrence, I will make it a standard practice to request winds when cleared for takeoff (though it is sometimes not practical when given takeoff clearance, heading to fly at DME fix, and traffic, all in one sentence, to ask for one more piece of information).

Title: ACR B727 FLC IS MADE AWARE ON INITIAL CLBOUT THAT WIND FACTORS HAD CHANGED, NULLIFYING DEP RWY TKOF CRITERIA. NO NOTICEABLE WIND EFFECT WAS OBSERVED WITH ACFT CLB CHARACTERISTICS.

Narrative: TKOF RWY 27 MEMPHIS INTL. LATEST ATIS GAVE WINDS OF 140 DEGS/6 KTS, LOW LEVEL WINDSHEAR ALERT IN EFFECT. NO OBVIOUS WINDSHEAR PRESENT TO AIRCREW. CLRED FOR TKOF. ONCE AIRBORNE AT APPROX 1000 FT, TWR WAS HEARD ADVISING NEXT ACFT FOR RWY 27 THAT WINDS WERE 90 DEGS 12 KTS, WHICH ARE BEYOND MAX TAILWIND FOR B727. SUSPECT WINDS WERE OBSERVED INCREASING TO OUT OF LIMITS AS THAT ACFT WAS PREPARING TO TAKE RWY. MY ACFT WAS NOT ADVISED OF ANY WINDS NEAR OR OUT OF LIMITS. TKOF WAS NORMAL IN ALL RESPECTS, WITH NO NOTICEABLE WIND EFFECT UPON ACFT. SUPPLEMENTAL INFO FROM ACN 409641: ON PRE-DEP BRIEFING, DISCUSSED WINDSHEAR PROBABILITY, AND GIVEN LIGHT WINDS AND NO CONVECTIVE ACTIVITY IN VICINITY OF ARPT, WE FELT IT WAS NOT A FACTOR, BUT WOULD REMAIN ALERT FOR ANY CHANGES. TO AVOID A SIMILAR OCCURRENCE, I WILL MAKE IT A STANDARD PRACTICE TO REQUEST WINDS WHEN CLRED FOR TKOF (THOUGH IT IS SOMETIMES NOT PRACTICAL WHEN GIVEN TKOF CLRNC, HEADING TO FLY AT DME FIX, AND TFC, ALL IN ONE SENTENCE, TO ASK FOR ONE MORE PIECE OF INFO).
