Determine the NAM given a NGM of 180 NM, TAS of 165 kt and GS of 150 kt:

  • A
    198 NM
  • B
    164 NM
  • C
    165 NM
  • D
    180 NM

To get Air Miles Multiply by Air Speed:

Multiply the couple Ground Miles/Ground Speed by (True) Air Speed.

  • NAM = NGM x TAS / GS
  • NAM = 180 x 165/150
    NAM = 198 NM
