本航空航天标准确立了主要用于往复式发动机动力运输飞机的歧管压力仪表的基本最低安全性能标准，其运行可能会使仪表受到第3.3节规定的环境条件的影响。本航空航天标准涵盖以下两种基本类型的歧管压力仪表:I型-直接指示。II型-远程指示。

This Aerospace Standard establishes the essential minimum safe performance standards for manifold pressure instruments primarily for use with reciprocating engine powered transport aircraft, the operation of which may subject the instruments to the environmental conditions specified in Section 3.3. This Aerospace Standard covers two basic types of manifold pressure instruments as follows: TYPE I - Direct Indicating. TYPE II - Remote Indicating.
