Scope
The purpose of this AIR is to provide recommendations for the minimum dimensions of characters and symbols used in aircraft instrument dials and panel displays as related to the conditions stated in para. 3.
Numerous variables influence the legibility of aircraft instrument dial characters. This situation makes it very difficult, if not impossible, to establish an exact act of rules for optimizing all installations.
Character size, one of the important considerations, can be optimized where adequate dial space exists. Usually this is not the case and the designer is faced with placing the information in a limited space while continuing to strive for error-free legibility. Appropriate minimum size requirements have been stated herein for guidance in air transport use.
Rationale
This Technical Report contains no changes from the previous revision, other than the addition of a Stabilization Notice Page. This document has been determined to contain stable technical information which is not dynamic in nature.

Issuing Committee
A-4 Aircraft Instruments Committee
The A-4 Committee is responsible for mechanical, electromechanical and electronic cockpit instrumentation standards applicable to all civil aircraft, with emphasis on minimum performance standards intended for reference in the Federal Aviation Administration (FAA) Technical Standard Orders (TSO).
A list of the technical reports developed by the A-4 Committee can be obtained by searching on 'aircraft instruments' and selecting 'standards', from the SAE Home Page. A-4 Standards For additional information about the A-4 Committee or SAE, contact Maureen Lemankiewicz mlemank@sae.org Let us contact you about suitable committee participation opportunities. Advise us of an industry issue for an SAE Technical Committee.Reference

* Redlines comparisons are available for those standards
listed in the Revision History that contain a radio button. A
redline comparison of the current version against a revision is
accomplished by selecting the radio button next to the standard and
then selecting 'compare'. At this time, Redline versions only exist
for some AMS standards. SAE will continue to add redline versioning
with ongoing updates to SAE MOBILUS.
