Narrative:

I had done all the normal preflight planning (density altitude; takeoff; endurance; etc) and then proceeded to take off. I did take off; however I was unable to climb out. Instead of proceeding into turn at a low altitude; I turned west into a wooded area. Still attempting to climb; I performed a 180 degree turn and headed back to the airport. At this point; I contacted the tower; declared an emergency; and requested landing. I was given permission and I landed without problem. My feeling is that the airplane is old (1968) and the graphs/charts are for a new airplane. So at a high density altitude a C150 will not perform well; especially with any extra weight. In the future; I will not takeoff anywhere near the edge of the envelope.

Title: C150 PLT HAS PERFORMANCE PROBS DURING TKOF.

Narrative: I HAD DONE ALL THE NORMAL PREFLT PLANNING (DENSITY ALT; TKOF; ENDURANCE; ETC) AND THEN PROCEEDED TO TAKE OFF. I DID TAKE OFF; HOWEVER I WAS UNABLE TO CLB OUT. INSTEAD OF PROCEEDING INTO TURN AT A LOW ALT; I TURNED W INTO A WOODED AREA. STILL ATTEMPTING TO CLB; I PERFORMED A 180 DEG TURN AND HEADED BACK TO THE ARPT. AT THIS POINT; I CONTACTED THE TWR; DECLARED AN EMER; AND REQUESTED LNDG. I WAS GIVEN PERMISSION AND I LANDED WITHOUT PROB. MY FEELING IS THAT THE AIRPLANE IS OLD (1968) AND THE GRAPHS/CHARTS ARE FOR A NEW AIRPLANE. SO AT A HIGH DENSITY ALT A C150 WILL NOT PERFORM WELL; ESPECIALLY WITH ANY EXTRA WT. IN THE FUTURE; I WILL NOT TKOF ANYWHERE NEAR THE EDGE OF THE ENVELOPE.
