Flight planning

Route, fuel, and endurance planning for a trip, with a go/no-go banner computed live from the aircraft's performance profile — ground speed and ETE from cruise TAS and wind, enroute/reserve/taxi fuel, and the mandatory 91.167(a) alternate-fuel leg when 91.169 requires one — rather than a back-of-the-envelope fuel burn. It replaces the separate planning tool the department reached for before.

Who it's for

A corporate pilot who plans route, fuel, and endurance for a trip instead of reaching for a separate planning tool.

What it replaces

The separate planning tool the department reached for before, and a back-of-the-envelope fuel burn.

What flight planning gives you

  • Route, fuel, and endurance planning per trip
  • A live go/no-go banner computed from the aircraft's performance profile
  • Save as a draft, file it, then mark it flown

Route, fuel, and endurance, computed live

A corporate pilot builds a route, fuel, and endurance plan for a trip, and the numbers compute live from the aircraft's performance profile — ground speed and ETE from cruise TAS and wind, enroute/reserve/taxi fuel, and the mandatory 91.167(a) alternate-fuel leg when one's required — rather than a back-of-the-envelope fuel burn. It replaces the separate planning tool the department reached for before.

  • Route, fuel, and endurance planning per trip
  • The 91.167(a) alternate-fuel leg is included when 91.169 requires one

A go/no-go banner from the performance profile

The go/no-go banner computes from the aircraft's performance profile — route, fuel, and endurance together — as a planning aid the pilot reads before a trip. It is not a certified dispatch tool; the pilot in command stays the final authority.

How an operator uses this

A corporate pilot builds a route, fuel, and endurance plan for a trip, and a go/no-go banner computes live from the aircraft's performance profile — ground speed and ETE from cruise TAS and wind, enroute/reserve/taxi fuel, and the mandatory 91.167(a) alternate-fuel leg when 91.169 requires one — rather than a back-of-the-envelope fuel burn. The browser computes from the same pure engine the server persists with, so the numbers on screen match what's saved. A plan moves Draft → Filed → Flown. It replaces the separate planning tool the department reached for before, and it's a planning aid, not a certified dispatch release — the pilot in command stays the final authority (14 CFR 91.3).

Illustrative — every screen reflects what's in your own data, nothing more.

How it works

Flight planning, step by step

  1. Enter the route, cruise performance, and fuel onboard for the trip.

  2. Fuel and endurance compute live — ground speed and ETE, enroute/reserve/taxi fuel, and the 91.167(a) alternate leg when one's required.

  3. A go/no-go banner reflects the route, fuel, and endurance together, and flags a missing required alternate.

  4. Save the plan as a draft, file it, and mark it flown once the trip is complete.

Questions

Flight planning — frequently asked

Is flight planning available today?

Yes. Route, fuel, and endurance planning with a live go/no-go banner is live on /app/flight-planning for Part 91 flight departments.

Where does the go/no-go banner come from?

It computes live from the aircraft's performance profile — ground speed and ETE, enroute/reserve/taxi fuel, and the mandatory 91.167(a) alternate-fuel leg when 91.169 requires one. It's a planning aid; the pilot in command stays the final authority.

Every Part 91 workspace also includes the platform-wide backbone — logbook, credentials, compliance, reporting, and audit trail.
