Scope
The instrument system specified shall accept an input of static pressure and in some equipment other inputs that contribute altitude information to provide a visual indication of pressure altitude. If equipped with an automatic correction mechanism, it shall indicate by a positive means when the automatic correction mechanism is not in use. If the static source pressure error compensating mechanism is operational it shall be functional throughout the required operating envelope of the particular aircraft. Each aircraft type has its own static source error data which shall be obtained from the airframe manufacturer’s certified data. When a Central Air Data Computer is used in the altimeter system, the CADC shall be certified to its own governing document and the altimeter system (CADC and display) shall comply with the requirements of this document.
NOTE: The instrument system specified herein does not include the aircraft pressure lines and pressure sources.

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.
