ALC: This field represents the carrier’s three-letter airline code. Generally only one airline code is maintained on each system, however there is support for multiple airline codes should the user have the requirement to manage more than one airline code.
Approach and Minima Section
Field | Description |
Landing Approach | STARS and DCT to the airport will use a landing approach if (Y) is selected. |
Types | Override allowed approach types (ILS, RNAV, etc) and order them in priority. Further information on what each letter represents can be found in the Approach and Minima article. |
Minima Src/Std | What is the minima data source (A)lc Only, (C)ommon or (B)oth and what is the Minima Regulatory Standard (P)art OPS, T(E)RPS, (T)P308 or (S)tate |
Minima Fallback | Defines system behavior when no minima are available for the selected runway at the destination airport. Options are:
|
Check Crew Qual | Controls whether crew approach qualification checks are enabled. Options are Y(es) or N (no).
|
Default Weather Minima Section
Field | Description |
Orig | Enter the minimum and warning values for ceiling (feet) and visibility (meters) for origin stations. |
Dest | Enter the minimum and warning values for ceiling (feet) and visibility (meters) for destination stations. |
Other | Enter the minimum and warning values for ceiling (feet) and visibility (meters) for other stations. |
Alt Rwy Mnm Buf Section
Information about this is also found in FOMS 170 Page 3.
Field | Description |
Normal | Enter the minimum and warning values for ceiling (feet) and visibility (meters) for alternate station. |
1Rwy | Enter the minimum and warning values for ceiling (feet) and visibility (meters) for alternate station with only one runway. |
>1Rwy | Enter the minimum and warning values for ceiling (feet) and visibility (meters) for alternate stations with more than one runway. |
High Minima Buffers Section
Defines which increase destination approach minima for High Min crew members can control ceiling and visibility buffers placed on minima.
Field | Description |
Ceiling | Enter ceiling buffer for high minima in feet. |
Visibility | Enter visibility buffer for high minima in meters. |
Dest Alternate Approach Minima Section
Field | Description |
Buffer Rule | Options are:
|
Allow Reciprocal |
1PA: Enter the ceiling (in feet) and visibility (in meters) buffer to be applied to approach minima at the alternate station when using a single precision approach to determine alternate minima. If the user has selected Buffer w/ Minimum Value, you will also be able to enter the minimum values for ceiling (in feet) and visibility (in meters). 2+PA: Enter the ceiling (in feet) and visibility (in meters) buffer to be applied to approach minima at the alternate station when using two or more precision approaches to determine alternate minima. If you selected Buffer w/ Minimum Value, you will also be able to enter the minimum values for ceiling (in feet) and visibility (in meters) |
Enr Alternate Approach Minima Section
Field | Description |
Buffer Rule | Options are:
