it is not intended to discuss all of the various GFMPL
programs available, only those commonly used by
several warfare communities. Table 2-1 lists the most
widely used OAML models and table 2-2 lists the data
bases contained in OAML.
The OAML data bases and models are used in
data bases as you progress into a senior Aerographer’s
Mate.
REVIEW QUESTIONS
Q1.
What is the purpose of OAML?
TESS, IMOSS, MIDDS, and many other environmental
prediction systems used throughout the fleet. You will
learn much more about the use of OAML models and
