Maintenance of Pitot-Static Systems of Transport Aircraft

2020-02-20

CURRENT

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 pressures 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.

ARP667

This recommended practice establishes objectives for high performance control motor tachometer generators to be used with aeronautical and associated equipment in protective enclosures or completely within the shell of the aircraft so that they are subjected only to the internal climatic conditions of heat, cold, shock, vibration, and humidity. Control motor tachometer generators larger than size 23 are not covered in this document.

MINIMUM PERFORMANCE STANDARD FOR BANK & PITCH INSTRUMENTS

2008-02-16

CURRENT

AS8001

This Standard covers Bank and Pitch Instruments which measure and display the angular displacement of bank and pitch from a gyroscopic vertical reference. This reference may be pneumatically or electrically driven and be contained within the instrument display case or located remotely. Unless otherwise specified, whenever the term "Instrument" is used, it is to be understood to be the complete system of gyro component, any auxiliary equipment and display.

AS8014

This Aerospace Standard covers two basic Stall Warning Systems, one measures air flow and pressure distribution on the airfoil and the other measures the angle of airflow with respect to an arbitrary reference line. Each type of system includes, as a minimum, a sensor and the means for activating a device which warns the pilot of an impending stall.
