speed of light? correct answers 186,000 miles per second
Outside air temperature (OAT) (also known as true air temperature (TAT)) is determined by
what? correct answers Correcting the measured or indicated air temperature for compression and
friction heating.

parallel? correct answers perpendicularly
In thermal circulations the strong the temperature gradient results in what? correct answers
stronger pressure gradient and stronger wind
When the isobars on the surface analysis chart are close together, the pressure gradient force is
what and winds are what? correct answers Pressure gradient force is large and wind speeds are
strong
Isobaric patterns infer what about wind? correct answers direction
