Airport chart
Landing Minima
As per chart for ceiling and visibility
Alternate Requirements - Weather
Cloud - more than SCT below Alternate Minimum
Visibility - Below Alternate Minimum
or - Above Alternate Minimum with forecast perentage etc below
Wind - Crosswind or Tailwind more that max for Aircraft
INTER
30 Min Holding fuel
TEMPO
60 Min Holding fuel
ETU - Expected Time of Use
The ETA (rather than the operational requirement) that has the 30 - minute buffer, with the operational requirement then compared to this window. This results in the same operational outcome for weather forecasts however expands the concept to include additional operational factors such as NOTAMs, lighting & TAF validity.
Are INTER and TEMPO requirements cumulative
No
FM or BECMG buffer
30 min
unless inside TAF3 first 3 hours.
TAF3 requirements
If airborne and within 60 minutes flight time to the aerodrome of intended landing, the
Alternate Minima may be used to determine if a Destination Alternate is required,
providing the Destination:
* Has an available TAF3;
* Sufficient holding fuel is carried for the expected traffic holding; and
* The period from the ETA -30 to ETA +60 minutes is wholly encompassed within the
first three hours of a TAF3 (consecutive TAF3s may be combined to meet this
requirement).
