// 01 · FREE ENVIRONMENTAL BRIEFING
FROM AIRPORTS
TO SOURCES.
Designed to put environmental information and its limitations in one place, without pretending to replace official sources or the operator's procedures.
Inspect the sources.
Examine available weather, NOTAM, historical GPS interference, global space weather and experimental airport RAIM—with provenance and data-status warnings.
Take the briefing.
Generate a Pilot Brief or Full Source PDF from the briefing. Source documents and operator procedures remain authoritative.
// 01 · The problem
Nine tools. Nine formats. One preflight.
Checklists, PDFs, weight and balance sheets, performance charts, weather, NOTAM, GNSS services, fuel checks and company risk forms, each in its own window. ROTORCORE brings them into one continuous workflow built for helicopters.
Each source is correct. None of them talk to each other. The crew is the integration layer.
The same information, entered once and carried through one helicopter-native sequence. Official sources, approved manuals and operator procedures remain authoritative.
// BEYOND THE FREE BRIEFING
The briefing is only the beginning.
ROTORCORE connects cockpit references, checklists and mission preparation in a helicopter-focused EFB suite. Dispatch Mode is in development.
// 02 · Current capability
Seven checks. One flow.
Every module states what it does and where it stops. Select one to open it.
Available
See the load. See the CG. Before you lift.
Build the cabin configuration, enter crew, passengers, baggage and fuel, and check total weight and centre of gravity against the configured longitudinal and lateral envelopes.
Limitation
Uses operator-provided aircraft data. The approved Weight & Balance method and the aircraft documentation remain authoritative.

Advisory
ROTORCORE RAIM Engine
GNSS integrity prediction, even where official coverage stops.
For a planned location and time window, the engine produces an independent, advisory prediction of whether the expected satellite geometry can support the integrity the operation requires.
Where a supported official service covers the location, ROTORCORE uses it. Where it does not, the engine provides the prediction instead. The crew stays in one workflow and always sees which provider produced the result.
RAIM is an established aviation concept. What is proprietary is ROTORCORE's engine, its implementation and its place in the preflight workflow.

In development
Advisory only. ROTORCORE RAIM does not replace certified avionics, approved navigation equipment, required official prediction services, operator procedures or regulatory obligations.
// 04 · Briefing context
Two different questions.
The briefing keeps integrity prediction and interference history apart, because they answer different things. Alongside them: METAR, TAF and NOTAM for the covered airports, and space weather.
RAIM · advisory prediction
Will the expected satellite geometry provide the required integrity for the planned time and location?
See the engine ↑
Interference · historical open source
Where was GNSS disruption recently observed?
Observations from a public open source, typically from the previous day. They provide context only and do not predict what will happen during the flight.
Historical D–1 context
Not real-time
Not an onboard RF detector
// 05 · Built for the cockpit
Four things it does not trade away.
Safety
Advisory stays labelled advisory. Every limit is stated where the result appears.
Standardisation
The same sequence and the same layout for every crew and every aircraft in the fleet.
Compliance
Built around the operator's approved procedures and documentation, never in place of them.
Autonomy
The cockpit does not depend on a signal. Critical information stays available offline.
See it in the light you fly in.
The interface runs in day, night and NVG modes. NVG mode removes all red from every colour (R=0).
// 06 · What comes next
Coming soon — in development
Dispatch Mode
From the operations desk to the cockpit, as one controlled flight package. It is designed to save the desk and the crew from re-keying the same information.
01Dispatch preparesBriefing, W&B, route, flight plan, NOTOC, manifest and attachments.
02Versioned packageOne structured package with a version and a timestamp.
03Pilot reviews & signsThe crew reviews the package, signs it and sends it back.
04Traceable recordDesigned to keep every version traceable and tamper-evident, and available offline in the cockpit where applicable.
Future capability. Nothing in this section is presented as available today.
// 07 · Founder
Designed from the cockpit outward.
Every module started as a task that took too long, or a number that had to be copied between three tools. ROTORCORE was built to remove that friction, by someone who had to deal with it on every flight.

// 08 · Questions
What operators ask first.
Is ROTORCORE certified or approved?+
No certification or authority approval is claimed. ROTORCORE is an advisory tool. Whether and how it is used operationally is the operator's decision, under the operator's own approvals and procedures.
Which aircraft does it support?+
ROTORCORE is configured per operator, using that operator's aircraft data, layouts and procedures. Nothing is presented as universal to all helicopters.
Does it work without connectivity?+
Yes, where implemented. Checklists and configured cockpit information stay available offline. Briefing sources need a connection to refresh.
Is the GNSS interference information live?+
No. It is historical open-source data, typically from the previous day. It is not real-time, it is not an onboard RF detector, and it does not confirm whether interference is present or absent during a flight.
Does it connect to our company systems?+
ROTORCORE provides configured access to the tools the operator selects. It does not claim data integration, synchronization, single sign-on or automatic submission.
Is Dispatch Mode available?+
Not yet. Dispatch Mode is in development and is not available today.
