Briefing Fuel Plan

Casual & above

Personal fuel planning built right into your briefing — how much you have, how much you need, and exactly what to tell the truck.

What Is It?

The Briefing Fuel Plan is a lightweight fuel card that lives in your weather briefing under Route & Fuel. You enter your fuel on board, and PlaneWX calculates everything else: how much you need to be safe, exactly how much to add at the airport, the estimated burn, and what you'll land with.

It's separate from the Fuel Advisor — the Advisor finds the best fuel stop route for cross-country flights. The Briefing Fuel Plan is for any flight where you already know your route and just want a clear, at-a-glance fuel picture before you depart.

Your numbers, not a default. The plan is personal — it never appears on shared or crew views. Nothing is saved until you tap Save. You can always edit or remove the plan later.

How to Add a Fuel Plan

1

Open a briefing

On any Casual+ trip you own that doesn't already have a fuel plan, scroll to the bottom of the briefing. You'll see a dashed Route & Fuel card with an Add fuel plan button.

2

Check your aircraft profile

The button is enabled only when your aircraft profile has both a fuel capacity and a cruise fuel burn set. If the button is grayed out, tap it and follow the link to your aircraft settings to fill in those numbers.

3

Enter your fuel on board

Type how much fuel you have right now — before you go to the FBO. PlaneWX calculates everything from there.

4

Review the numbers and save

The card shows your Required FOB, how much to add at your departure airport, estimated burn, and estimated landing fuel. Tap Save when the plan looks right.

Save promotes to the required FOB. If the fuel you entered is below what you need for the leg plus reserve, tapping Save automatically records the Required FOB as your planned departure fuel — so you always depart with a safe load.

Understanding Each Field

W&B Max

Your weight-and-balance maximum fuel load. Leave it blank for full tanks. Set it when your aircraft W&B limits your usable fuel below tank capacity for a given loading.

Current FOB

How much fuel is in the tanks right now, before you go to the FBO. This is your starting point — enter the number from your fuel gauges or last fuel receipt.

Required FOB

The fuel you need in the tanks when you push off blocks: estimated leg burn plus your configured reserve (e.g. “leg + 45 min reserve”). This is the target to fuel to — it accounts for your aircraft's reserve settings, not a fixed number.

Add at [Airport]

Required FOB minus Current FOB — the number you give the lineman at the FBO truck. No mental math needed. Shown in amber when you need fuel; disappears once your FOB already covers the leg.

Est. burn

Projected fuel consumption for the leg: distance ÷ planned TAS × cruise fuel flow from your aircraft profile. This is a planning estimate — use your POH for exact numbers.

Est. FOD

Estimated fuel on descent — what you'll land with after the leg burn. Shown based on your post-fueling FOB (Required FOB) when you need to add fuel, so it reflects what you'll actually have, not what you have right now.

Quick Actions

Use required

Fills Current FOB to the Required FOB in one tap. Useful when you want to verify the Est. FOD before saving, or when you want to fuel exactly to the minimum safe load.

Fill to W&B max

Sets Current FOB to the W&B max (or full tanks if no max is set). A good choice when destination weather looks challenging and you want maximum divert margin.

Weather tip shown automatically. When the fuel advisory is active, the card reminds you to consider extra fuel if you expect storms at your destination or a possible divert. The Required FOB is the minimum — you can always load more.

Multi-Leg Journeys

If your trip is part of a linked journey — for example, KGDJ → KDTS → KGDJ — the fuel plan carries forward automatically when you save Leg 1. Leg 2's departure fuel is set to Leg 1's landing fuel plus the add-at-destination amount, so you don't have to recalculate the chain by hand.

Mid-journey legs

The destination line shows FOD · add N for next leg. The add amount is whatever you need so the following leg departs safely fueled.

Last leg (return)

The destination line shows FOD · add N to restore X FOB — restoring your home-base FOB so you know exactly what the tanks will hold when you land.

You can still edit each leg independently. Editing a leg updates that leg's plan; the sibling carry is applied fresh each time you save Leg 1. Downstream legs with no plan yet will be pre-filled when you add them.

Fuel Summary on the Dashboard

Once a fuel plan is saved, each leg card on your home dashboard shows a one-line fuel summary:

FOB 173.1g · FOD 60g · add 113.1g for KDTS→KGDJ

The full picture — what you depart with, what you land with, and what to add — at a glance without opening the briefing.

Aircraft Profile Requirements

The Briefing Fuel Plan needs two numbers from your aircraft profile:

Fuel Capacity (Usable Gallons)

Total usable fuel in gallons. Used to calculate the W&B max default (full tanks) and the “Fill to W&B max” button.

Cruise Fuel Flow (GPH)

Your typical cruise fuel burn. Used for Est. burn and Est. FOD. Make sure this is up to date for the most accurate numbers.

If either value is missing, the Add fuel plan button is disabled with a note to update your aircraft profile.

Frequently Asked Questions

Is this the same as the Fuel Advisor?

No. The Fuel Advisor finds multi-stop routes for cross-country flights. The Briefing Fuel Plan is a personal fuel card for any single leg — it shows up in the briefing you already have, with no route planning needed.

Can my crew or watcher see my fuel plan?

No. The fuel plan is personal. It never appears on shared or read-only briefing views.

What happens if I save with less fuel than the leg requires?

Save automatically promotes your departure fuel to the Required FOB so you always record a safe departure load. The advisory shows you the gap before you tap Save.

Can I delete a fuel plan?

Not yet — editing is available (tap Edit in the Route & Fuel card), but deletion is coming in a future update.

Does the reserve include alternate fuel or extra padding?

No. Required FOB = leg burn + the reserve you've configured on your aircraft profile (time-based or fuel-quantity). Adding extra for a potential divert or destination weather is your call — the Fill to W&B max button makes it easy.

Tips

  • Enter your fuel before you leave for the airport — the advisory tells you what to add before you even pull up to the truck.
  • For challenging weather or unfamiliar destinations, tap Fill to W&B max to give yourself the maximum divert margin.
  • On a multi-leg journey, add the fuel plan to Leg 1 first — the numbers carry forward to the return leg automatically.
  • Keep your aircraft's cruise GPH current. A stale burn rate produces a stale Est. FOD.

Fuel planning is your responsibility. Estimates are based on your aircraft profile and a simple burn model (distance ÷ TAS × GPH). Actual fuel burn varies with winds, power settings, weight, density altitude, and other factors. Always verify fuel loads against your POH, applicable regulations, and your own judgment before flight.

PlaneWX fuel calculations are a planning aid — the pilot in command is always responsible for ensuring adequate fuel.
