Bendix/King Radio Stack as found in the RealAir Simulations 172 (and many others)
This is a common arrangement of the radios and related equipment that comprise a well equipped (IFR) Aircraft radio stack.
Learn the names and positions of each component as well as how to set/adjust them, initially with emphasis on the NAV and Com radios in particular, as these will be used on your first flights with TX Flight Sim Ground School. If you know what the standby frequency of Nav 2 is, for example, it will make life a bit easier for all.
Also note that the "Comm Selector" is more aptly called the audio panel.
