Narrative:
After takeoff at about 300 ft, I had a stick shaker stall warning and a momentary 'slat' (amber) on the primary flight display. Condition lasted several seconds and disappeared. At about 600 ft the stick shaker started again along with an amber 'slat' annunciation on the primary flight display and a 'slat disagreement' alert on the electronic attitude display. This condition lasted about 10 seconds and disappeared. Airspeed was above V2 +10 KTS in both sits. Indications remained normal after slat and flap retraction. Flight continued to anc. On flap extension to 28 degree flaps, the 'slat disagreement' alert came on for 10 seconds and then disappeared. A normal landing was made.

Title: A LARGE COMMERCIAL FIXED WING CARGO ACFT ON TKOF EXPERIENCED THE STALL WARNING STICK SHAKER WITH MOMENTARY SLAT WARNING LIGHT. ALL NORMAL AFTER FLAP-SLAT RETRACTION.
Narrative: AFTER TKOF AT ABOUT 300 FT, I HAD A STICK SHAKER STALL WARNING AND A MOMENTARY 'SLAT' (AMBER) ON THE PRIMARY FLT DISPLAY. CONDITION LASTED SEVERAL SECONDS AND DISAPPEARED. AT ABOUT 600 FT THE STICK SHAKER STARTED AGAIN ALONG WITH AN AMBER 'SLAT' ANNUNCIATION ON THE PRIMARY FLT DISPLAY AND A 'SLAT DISAGREEMENT' ALERT ON THE ELECTRONIC ATTITUDE DISPLAY. THIS CONDITION LASTED ABOUT 10 SECONDS AND DISAPPEARED. AIRSPD WAS ABOVE V2 +10 KTS IN BOTH SITS. INDICATIONS REMAINED NORMAL AFTER SLAT AND FLAP RETRACTION. FLT CONTINUED TO ANC. ON FLAP EXTENSION TO 28 DEG FLAPS, THE 'SLAT DISAGREEMENT' ALERT CAME ON FOR 10 SECONDS AND THEN DISAPPEARED. A NORMAL LNDG WAS MADE.
