Barometry for Altimeter Calibration

2020-01-15
WIP
AIR1075B
This SAE Aerospace Information Report (AIR) is concerned only with aspects directly relating to available accuracy. While well-designed photoelectric, inductive or capacitive readers and pressure regulators, and other accessories are highly desirable for convenience and production rate, they are considered to be outside the scope of this AIR. This AIR is intended to define three classes of barometers, working, reference and transfer and some aspects of their use so that altimeters and air data transducers calibrated aginst working barometers will be comparable. An accuracy of ±0.003 inch (or ±0.076 mm) Hg should be approachable with working barometers meeting the recommendations in this AIR.

Numeral, Letter and Symbol Dimensions for Aircraft Instrument Displays

2020-01-15
WIP
AIR1093B
The purpose of this AIR is to provide recommendations for the minimum dimensions of characteris 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 considertions, can be optimized where adequate dial space exists. UIsually 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.

Maintenance of Pitot-Static Systems of Transport Aircraft

2020-01-15
WIP
AIR975B
In efforts to increase the accuracy and reliability of altimetry, speed measurement and other aspects of air data, a great deal of attention and money have been expended on new and refined pressure transducing and computing systems and on the standards by which they are calibrated. So much progress has been made in this that the limiting factor is, or may soon be, the sensing and transmitting in the aircraft of the pressure to be transduced. Until the appearance of References 1 - 13 and 18 there was little guidance available on the maintenance of pitot and static systems. This report presents what information is available, suggests limits, and lists the principal original papers on the subject. To set forth in a single document the principles and practices for maintenance of pitot and static pressure systems of transport aircraft.

AIR818E
This Aerospace Information Report, (AIR) is intended to provide the sponsors of Aerospace Standards, (AS), with standard wording, formatting, and minimum environment and design requirements for use in the preparation of their document. The individual shall use only those parts of this AIR which apply to their particular document. The individual sponsor may expand the standard wording, especially under Sections 4, 5, and 6 as required. The paragraphs of this AIR shall be used verbatim wherever possible. Unless otherwise directed by SAE, cross referenced documents shall be called out by specific revision letter, e.g. "shall be in accordance with AS XXXXB." In addition, all non-SAE documents called out shall include the document title when initially identified. However, every effort shall be made to keep cross-referencing to an absolute minimum.
