Meteorology and Flight Planning
1.
EXAMPLE 1--turbulence and icing level: The flight
Fig 28: Interpreting
plan states that your flight will be going from SPS to
the DD-175-1
ABQ at FL350, departing at 1900Z.
(Example 1)
NOTE: Be aware that the plane could encounter
icing from SPS to CDS at 1,000 ft AGL to 12,000 ft
MSL on climbout and will encounter severe
turbulence from TXO to ABQ between FL230 and
FL390. These phenomena affect how you decide to
proceed with your flight plan.
2.
EXAMPLE 2--destination forecast requires an
Fig 29: Interpreting
alternate: The flight plan states that your flight will
the DD-175-1
be going from NQI to NPA with PAM as an alternate,
(Example 2)
departing at 1730Z and flying at FL370.
NOTE: The alternate airfield is required because
the weather at the primary is below 3,000-3,
overcast at 500 and 1,400, thunderstorms and winds
at 20 kts gusting to 45.
3.
EXAMPLE 3--The proposed takeoff time very close
Fig 30: Interpreting
to void time of 175-1: flight plan states that your
the DD-175-1
flight will be going from NIR to ELP at FL350
(Example 3)
departing at 0000Z. You have been delayed for
maintenance.
NOTE: Be aware that because your revised takeoff
time of 0100Z will be after the VOID time, pilot(s) will
need to contact METRO to extend the VOID time
and perhaps receive a new briefing. In this case,
the forecaster rebriefs the pilot(s) at 0030Z and sets
a new void time of 0130Z.
4.
EXAMPLE 4--route of flight has a severe weather
Fig 31: Interpreting
warning (WW): The flight plan says your flight will be
the DD-175-1
going from NIR to TIK at FL370 departing at
(Example 4)
2200Z.
NOTE: The pilot(s) should be aware that a severe
weather warning (WW #25) is in effect between ALT
and ADM and should divert a portion of the flight
path west. Pilot(s) should ask forecaster about the
extent of the warning.
