Over the many years of Cessna 172 production, the stationary panel has been redesigned several times, which creates many different nonstandard layouts through the early years. It is a part of the aircraft’s structure and, according to the Cessna 172 service manual, considered not ordinarily removable due to being directly secured to engine mount stringers and a forward fuselage bulkhead. That structural piece is called the stationary panel. Instruments typically considered less sensitive, such as engine and temperature gauges, were often mounted directly to the structure behind the plastic. The shock panel is attached to the structure behind it using a set of rubber mounts, meant to isolate the sensitive instruments from the vibration of the aircraft. Once the plastic overlay was pulled off (or broken off due to age and wear), most of the instruments are contained in an aluminum panel known as the shock panel. The first was a plastic overlay, which revealed only the faces of the instruments and presented the pilot with a relatively pleasing and uncluttered view. The original instrument panel came in three parts.

When older models are purchased, owners often look at their jumbled instrument layout and consider how they can create that six-pack layout that they trained on. When compared to the 172N, P, R, and early S models, older models have nonstandard layouts that seem to lack symmetry and purpose. Modern Cessna 172s are equipped with impressive G1000 “Glass Cockpit” screens, but it is more likely that many pilots who learned in the Cessna 172 learned with “steam gauges” in a standard six-pack layout with a center radio stack. When was the last time you thought about why your instruments are arranged the way they are? Often the only time it is thought about is when a pilot is looking to upgrade their instruments or rearrange them to a more pleasing layout.
