BS 2G 201:1996

This standard BS 2G 201:1996 Specification for counter and pointer pressure altimeters is classified in these ICS categories:

• 49.090 On-board equipment and instruments

This British Standard specifies the general design and performance requirements for pressure altimeters having a combined counter and single pointer presentation in two forms as follows.

1. Type A. A panel-mounting indicator operating from any form of remote altitude transducer.
2. Type B. A panel-mounting indicator containing its own sensing mechanism inside the case.

The standard provides for instruments operating over an indicated range of–1 000 ft to + 50 000 ft (geopotential).

The design may include provision for applying corrections to the aircraft static pressure system error.
