A C172 has been the default aircraft in [[FlightGear]] since 2000, when it replaced the [[Navion]]. It has had a long development and includes a wide variety of simulation features. In 2015, it went through a complete refresh, including engine options, various tire sizes and floats.

The new | The new C172p has a much better 3D model and is now fully textured (including the interior). All the buttons in the cockpit are clickable. It also has an improved FDM, more complex procedures and new realistic checklists, new sound effects, and damage modeling. The aircraft can get damaged if mishandled (e.g. gear collapse after a hard landing). | ||

The pilot must then use the Cabin Heat and Cabin Air levers (on the right of the flaps) to control it. Alternatively, it's possible to disable the effect in the "Aircraft Options" in the "Cessna 172P" menu. This effect depends on the new ALS effects found in 3.5 and above, and will also have the side effect of producing grey windows in versions prior to 3.5. | ||

The aircraft may enter into a spin in case of an asymmetric stall (a particularly dangerous situation when turning to final, in which case the aircraft is at low speed and low height). The FDM has also been tweaked to include hydrodynamics effects while taking off or landing on water, as well as adding a new 180 HP engine. | ||
