So I went flying a 172s with another pilot this weekend. It was a 2008 SP model. I noticed the other pilot used flaps-10 on every takeoff. I didn’t think much about it, but he also didn’t cleanup until 700 AGL. When I asked why – he said his instructor had recommended this. Later, during a descent 8 miles away from the airport, he put in flaps-10. Again, he said his instructor had advised. I'd been flying S models for years and never seen this. And I've never had an instructor recommend this either. I checked the POH to see where this idea might have come from. I was surprised to discover Cessna now recommends flaps-10, even for a normal takeoff, and to only retract at a “safe altitude”. A check of descent procedures leaves flaps to pilots discretion, but since they mention flaps in the checklist – it’s easy to see where someone would consider during descent normal. Just wondering what other S drivers are doing?
