# Use the OFP Brief

The OFP Brief is the main in-flight reference view. It combines the parsed OFP with editable pilot-entered data.

## <mark style="color:$warning;">Review the hero and fuel plan</mark>

Start with the route header and fuel plan.

1. Confirm the flight, route, date, aircraft, and registration.
2. Confirm STD, STA, estimated takeoff, and estimated block time.

1. Enter actual block fuel when available.
2. Review taxi, trip, contingency, alternate, final reserve, hold, planned minimum, and preliminary block fuel.

## <mark style="color:$warning;">Track waypoint progress</mark>

The waypoint table lets you compare planned and actual progress.

| Field      | Use                                                      |
| ---------- | -------------------------------------------------------- |
| ATA        | Enter the actual time at a waypoint.                     |
| AFOB       | Enter actual fuel on board.                              |
| Notes      | Store VHF, HF, XPDR, CPDLC, or other waypoint notes.     |
| Current FL | Record an actual flight level if different from the OFP. |
| Alarm      | Set a UTC reminder for a waypoint.                       |
| Direct-To  | Mark skipped waypoints as abeam.                         |

## <mark style="color:$warning;">Understand fuel colors</mark>

AvComp projects expected fuel using the OFP planned EFOB curve. When you enter actual FOB, later waypoints recalculate from that anchor.

| Color                                      | Meaning                                                  |
| ------------------------------------------ | -------------------------------------------------------- |
| <mark style="color:$success;">Green</mark> | Actual fuel is close to or above the projected value.    |
| <mark style="color:$warning;">Amber</mark> | Actual fuel is below projection and should be monitored. |
| <mark style="color:$danger;">Red</mark>    | Actual fuel is significantly below projection.           |

## <mark style="color:$warning;">Use notes and frequencies</mark>

Tap a waypoint note field to enter:

* VHF frequency.
* HF 1 or HF 2.
* XPDR code.
* CPDLC or other text.

VHF entries can propagate forward to the next FIR boundary, helping reduce repeated typing.

## <mark style="color:$warning;">Send alternates to Alt Calc</mark>

Use the OFP alternates section to send alternate airport and fuel data to Alt Calc. Alt Calc can then use the OFP data as a starting point for holding and last-exit calculations.
