If it's warm and wet, the engine may very well ice up at reduced power without the proper precautions. At sea level and lightly loaded, the 182 gives an impression of being big and brawny, especially when compared to its lighter Cessna and Piper siblings. But take it to the high country where the engine is putting out much less power, and load up some friends with camping gear. The climb performance is underwhelming. One final area worth noting is the high number of landing accidents in the 182.
Most aircraft have a higher incidence of landing accidents than any other phase of flight.
It is the leading cause of pilot-related causal factors by a large margin and is higher in the 182 than the comparable aircraft. Fortunately, most of these accidents cause more damage to the airplane than to the occupants, but it relates to proficiency and understanding the landing dynamics of a heavier aircraft. The 182 is known to be heavy on the controls, and pilots apparently expect more float and lighter pitch forces on touchdown. Nearly half the landing accidents are due to hard landings, which generally result in collapsed nose gears and bent firewalls. It's hard to imagine overshooting a runway with the huge 182 flaps, but perhaps there is an overreliance on them to save the bacon on a bad approach if the aircraft is high.
