meteorological matters which are common to 

 all Federal agencies. These Handbooks, entitled 

 "Federal Meteorological Handbooks," contain 

 meteorological practices and procedures common 

 to all Federal agencies. Individual agencies may 

 issue addenda to cover policies peculiar to their 

 agency. However, these addenda apply only to 

 the issuing agency. Changes to the FMHs will 

 be coordinated and issued by the Working Groups 

 responsbile for the handbooks. These changes 

 will be made to the handbooks immediately and 

 the proper entry made on the handbook's Record 

 of Changes page. The NAVAIR number of each 

 FMH is directly related to the FMH number; 

 i.e„ FMH No. 1 is NAVAIR 50-1D-1, FMH No. 

 2 is NAVAIR 50-1D-2, etc. A brief description 

 of the effective FMHs follows.

 contains a comprehensive background on ba- 

 rometry; a description of the various pressure 

 measuring devices and their related equipment; 

 pressure-instrument calibration methods; meth- 

 ods of computing the required pressure data; 

 and a compilation of tables used in pressure 

 computations.
