General Aviation Cockpit Instrument Cutout Standards
(OP)
Does anyone know if there is a specification or standard that defines typical instrument cutouts and fastener patterns for an aircraft like a Cessna 172?





RE: General Aviation Cockpit Instrument Cutout Standards
cut-outs are defined by the instruments.
lay-outs (of the instruments) is something different, if that's what you're after.
RE: General Aviation Cockpit Instrument Cutout Standards
Standards enables cometition among avionics manufacturers and that competion helps keep prices down for operators.
I don't expect things to be as well defined in GA, but I'm certain every instrument OEM wants you to retrofit to their product as easily as possible.
Airframe builders usually want to drill one set of holes that works for most reasonable customer choices too.
RE: General Aviation Cockpit Instrument Cutout Standards
The panels are analyzed or tested for your particular instruments and panel configuration.
It isn't as tightly controlled presumably because the consequences of a GA aircraft having issues doesn't impact quite as many people.

MS28055, FLANGES, MOUNTING, ATTACHABLE, AIRCRAFT INSTRUMENT
and
MIL-F-6836, "Flanges, Mounting, Attachable, Aircraft Instrument"
From the MIL specs, you can also find the relavant instrument case bodies, fasteners, materials, etc, in addition to the dimensions.
