ambient temperature increase
What sort of atmospheric conditions would decrease or reduce aircraft takeoff and climb performance?

4 (one per thing)
What is the minimum number of Global Positioning System satellites that are observable by a user anywhere on Earth?
AIRMET's are advisories of significant weather phenomena but of lower intensities than SIGMET's and are intended for dissemination to whom?
