International Weather Flashcards
Can you deviate from your oceanic route for weather without attempting to get a deviation clearance?
(Atlantic Hi/Lo 1/2, Tab 2, mid panel)
• No, you must attempt to get a deviation clearance. If you cannot obtain the deviation clearance, you can deviate and obtain a deviation clearance at the earliest possible time.
(EXHIBIT 4) What does the highlighted field represent, on the METAR at UHHH?
UHHH 031900Z 01007MPS CAVOK M07.M17 Q0998 NOSIG
• Wind 010 At 7 Meters Per Second, (multiply by two, gives you 14 KNOTS)
