FAR 91.179

East 360-179 = Odd thousands

West 180-359 = Even thousands

67
Q

What is a Crossing restriction on a Standard Terminal Arrival Route (STAR)?

A

It represents the altitude required cross a fix

  • An altitude listed above a line indicates that you must be at or above that number
  • An altitude BETWEEN two lines means that you must be at that specific altitude
  • An altitude BELOW a line means that you cannot be higher than that number
68
Q

How should you complete your Descent Planning to meet the altitude restriction of a STAR?

A
  • Plan 3nm for every 1,000ft of altitude to be lost
  • Divide GS by 2 and multiply by 10 to get your FPM descent rate

*example:
GS = 100.
100/2 = 50
50 X 10 = 500 FPM

69

A

MCPRAWNT

M - MOA
C - Controlled firing area
