Narrative:
Departed 8s2 (1800 ft runway) with 4 on board in 80 degrees outside air temperature. Prior to departure, I did not do density altitude and aircraft performance calculations. On the upwind I was unable to achieve more than a 50 FPM climb rate. Standard left traffic crosswind is a turn toward rising terrain and with our lack of climb capability we would not have cleared it. I made a right crosswind toward descending terrain which allowed me to achieve a flyable airspeed. For about 1 mi I was below the 1000 ft AGL minimum for population dense areas. Once I attained a flyable airspeed, I initiated a gradual climb to 2500 ft MSL and returned to eat (pangborn) for a successful landing. In the future, I will be attentive to density altitude and performance calculations. More training in that regard would have been helpful.
Original NASA ASRS Text
Title: A C172 PVT PLT TAKES OFF WITH 3 PAX ON A HOT DAY AND HAS TO OVERFLY A DENSELY POPULATED AREA AT A LOW ALT WHEN THE ACFT FAILS TO PERFORM AS EXPECTED OUT OF S82, WA.
Narrative: DEPARTED 8S2 (1800 FT RWY) WITH 4 ON BOARD IN 80 DEGS OUTSIDE AIR TEMP. PRIOR TO DEP, I DID NOT DO DENSITY ALT AND ACFT PERFORMANCE CALCULATIONS. ON THE UPWIND I WAS UNABLE TO ACHIEVE MORE THAN A 50 FPM CLB RATE. STANDARD L TFC XWIND IS A TURN TOWARD RISING TERRAIN AND WITH OUR LACK OF CLB CAPABILITY WE WOULD NOT HAVE CLRED IT. I MADE A R XWIND TOWARD DSNDING TERRAIN WHICH ALLOWED ME TO ACHIEVE A FLYABLE AIRSPD. FOR ABOUT 1 MI I WAS BELOW THE 1000 FT AGL MINIMUM FOR POPULATION DENSE AREAS. ONCE I ATTAINED A FLYABLE AIRSPD, I INITIATED A GRADUAL CLB TO 2500 FT MSL AND RETURNED TO EAT (PANGBORN) FOR A SUCCESSFUL LNDG. IN THE FUTURE, I WILL BE ATTENTIVE TO DENSITY ALT AND PERFORMANCE CALCULATIONS. MORE TRAINING IN THAT REGARD WOULD HAVE BEEN HELPFUL.
