182 thermal shock

Howdy,
Anyone out there flying a 182 on parachute ops? What power settings and airspeeds do you use for descent?What sort of times are you looking at to get down from 10,000ft?
Cheers

The guys at Warnervale used to use a C182 for PJing. Dunno whether they still use it or indeed still operate. Try the phone book or yellow pages online (Central Coast, NSW). In a C185 I used to use 18" and 2000 rpm for descent, but I would suggest ALWAYS using the power setting that you are told to use by the owner or operator, after all, it is his a/c.

Cjam,
I'm currently flying a 182 on parachute ops and as soon as the meat bombs are away company ops have us setting 18" 2300rpm, 145kts and maintaining this all the way down. Descent rate is generally over 2000fpm so about 4mins to the circuit pattern.

The procedure I used in the 182 (H model-1965) was cowl flaps closed and 20" 2000 rpm and a lean mixture 1 1/2 miles or 1 minute before the drop, then hold 20" 2000 rpm and a lean mixture (around 150 kts) all the way down to base then a slow reduction of power slowly bring the mixture to full rich and a slow increase in pitch till full fine on finals. have used this procedure on 600 odd hours of skydive ops and ive never cracked a pot average sortie time of 0.5 for 5 pob and 0.6 with 6 pob (tacho). we did use 20" and prop full course for a while but we blew out the prop guvenor within 100 hours.

Thanks for that, it is fairly similar to what the owner has me doing,
150kts with the power coming back slowly so you hit 15" by circuit height.
