The brief, read the way a captain reads it.

TEMassist assembles your plan — weather, NOTAMs, threats, error and management — into one briefing. Nothing invented. Nothing hidden. The gaps, shown.

Pre-flight briefing release

A briefing, not a dashboard.

Most pre-flight tools hand you a wall of numbers and a colour legend to decode. TEMassist reads the plan the way an experienced crew does — what matters, what to watch, and what isn’t there. Built for SimBrief flight plans, tuned for pilots who fly for real.

Read like a crew
Threats ranked the way a captain would, not the way a database happens to store them.
Grounded in the plan
Every call traced to the OFP, the TAF, the NOTAM. If it isn’t in the data, it isn’t claimed.
Honest about gaps
What we couldn’t place or verify is shown as a gap — never smoothed into a green.

Deterministic. No model writes your brief.

02 — The brief

The brief. Every surface of the flight.

Below is not a mock-up. It is the briefing engine's own output for a sample flight, rendered by the same code that renders a real one.

Local knowledge
Adhere to curfew restrictions: Takeoffs limited to Runway 16R only, with taxi clearance required prior to the cutoff time.
Do not commence taxi if departure clearance is received after the curfew window unless a dispensation has been granted for specific emergencies.
Ensure crew passports and declaration forms are available for Border Force inspection before pushback or post-flight duties.
Report any use of reverse thrust beyond idle immediately to ATC.
Expect radar vectors rather than standard departure procedures.
Confirm parking bay assignments and marshalling requirements prior to arrival at the stand.

Nothing lit unless it needs you

The annunciators are dark at zero. A panel where everything glows tells a crew nothing — so dark means checked and clear.

Every verdict shows its operands

The window it was resolved for, the bulletin it came from, the wind it was computed against. A conclusion you cannot check is a conclusion you cannot use.

Nothing is deleted, only dimmed

Critical, High, Medium, All — the reader chooses what is surfaced, and the control always states what it is holding back.

Why it’s different

Two surfaces, one truth.

A deterministic card renders on every tier — the hard facts, always. The assessment layer adds what a crew would infer, and when it can’t, it says so. The map renders whatever the engine already produced: same component, honest content, no second source.

What’s included

A full pre-flight briefing from your SimBrief plan — take-off, enroute, landing, weather, NOTAMs, threats, error and management.

The trial

Twenty full briefs, then the standard brief for fourteen days. No card, no countdown.

The honest part

Where TEMassist is limited — what it can’t place, what it doesn’t cover — is stated plainly, here and in every brief.
