Helicopter cockpit at night, tablet mounted on the instrument panel.

Helicopter mission & preflight suite

The mission startsbefore the rotors turn.

ROTORCORE brings helicopter mission preparation, operational references and advisory decision-support tools into one cockpit-ready workspace.

Weight & balance, environmental briefing, digital checklists, operator-authorized QRH access, fuel cross-checks, Power Assurance Check and GNSS integrity prediction — configured around the aircraft and the operation, not adapted from fixed-wing tooling.

// 01 · The operational problem

The information exists. The workflow is the problem.

Preparing a single flight can send a crew across checklists, PDF documents, weight-and-balance tools, performance references, weather and NOTAM sources, GNSS integrity services, fuel verification and company risk or reporting tools. ROTORCORE reduces that fragmentation by bringing those flows into one continuous, helicopter-oriented operational environment.

  • Embedded referenceQRH provided by the operator
  • Tailored proceduresChecklists built to operator requirements
  • External sources, one viewEnvironmental briefing · weather, NOTAM, GNSS
  • Aircraft toolsWeight & balance · PAC · fuel check
  • Company systemsConfigured access to operator-selected tools

One hub, not one more tool. Operator-provided content, external services and ROTORCORE advisory calculations sit in the same workflow — and every result still shows where it came from.

ROTORCORE does not replace official sources, approved manuals, certified systems or operator procedures. Those remain authoritative.

// 02 · Who it is designed for

Rotary-wing crews and the desks that support them.

ROTORCORE is built for operations where the aircraft is a helicopter and the configuration is specific to the fleet — not for a generic aviation audience.

  • Helicopter pilotsSingle-pilot and crewed operations preparing and flying the mission.
  • Operations departmentsThe desk that prepares, checks and hands over flight information.
  • Helicopter operatorsFleets that need tools configured to their aircraft and procedures.
  • HEMS operationsShort-notice tasking where preparation time is the constraint.
  • Offshore operationsRepeated sectors with load, fuel and environmental checks every leg.
  • SAR & special missionsOperations where the plan changes after the briefing starts.

// 03 · Current capability

One mission. Seven connected checks.

Each capability states what it is, what it is for, what it resolves and where its operational limit lies. Select a step to open it.

Weight & Balance

See the load. See the CG. Before you lift.

Represent the cabin configuration, record crew, passengers, baggage, equipment and fuel, and calculate total weight and centre of gravity. ROTORCORE presents the result against the configured longitudinal and lateral envelopes, alongside the configured weight-altitude-temperature limits, so the crew gets a fast visual cross-check instead of re-reading a spreadsheet.

  • Cabin-layout configuration
  • Station weights
  • CG longitudinal & lateral
  • WAT limitations
  • Fuel & unit support

Uses operator-provided aircraft data. The approved Weight & Balance method and the aircraft documentation remain authoritative.

// 04 · Proprietary engine

ROTORCORE RAIM Engine Advisory

Integrity prediction. Coverage without guesswork.

The crew enters a location and a time window. ROTORCORE checks whether a supported official prediction service covers it and makes that path explicit. Where supported official coverage is not available, the proprietary ROTORCORE RAIM Engine produces an independent advisory prediction inside the same preparation flow.

What it is

A proprietary engine that generates an independent, advisory GNSS integrity prediction for a given location and time window, integrated into the ROTORCORE workflow.

What it is for

It helps the crew judge whether the expected satellite geometry can support the integrity requirements associated with the planned operation.

What it resolves

There are locations where supported official services provide no coverage, or cannot be used directly inside the preparation flow. ROTORCORE keeps the query in one place and makes visible which provider produced each result.

Terminology

RAIM is an established aviation concept. ROTORCORE did not invent it. What is proprietary is the engine, its implementation and its integration into the ROTORCORE workflow.

// Technical detail In development

How the engine decides, what it uses, where it stops. Written for the person who has to justify an advisory GNSS result to a chief pilot or an authority — the workflow, the inputs, the output and the stated limits.

Advisory only

ROTORCORE RAIM does not replace certified avionics, approved navigation equipment, required official prediction services, operator procedures or regulatory obligations. Internal thresholds, algorithms and implementation detail are not published.

// 05 · Two different questions

Integrity is predicted. The briefing is gathered.

One is a calculation about the future; the other is a briefing picture drawn from external sources. The page keeps them apart so the difference cannot be misread.

RAIM · integrity

Will the expected satellite geometry provide the required level of integrity for the planned time and location?

A forward-looking calculation. It is computed for the window the operation is planned in, and the provider that produced it is shown with the result.

InputPlanned location + time window
ComputedOn request, for the planned window
ProviderOfficial service where covered · ROTORCORE engine where not
OutputAdvisory integrity prediction
UseInput to the crew’s own decision
Applies to the integrity prediction Preflight prediction, not monitoring Not a receiver status readout Not a replacement for certified avionics

It informs planning. Required official prediction services and operator procedures still apply.

Briefing context

What is the environment around the operation — and where was GNSS disruption recently observed?

The briefing gathers the operational picture for the covered locations: weather, NOTAM, space weather and open-source GPS degradation reporting, each labelled with its source and how current it is.

METAR / TAFCovered airports · configured source
NOTAMCovered airports · configured source
Space weatherConfigured source
GPS degradationOpen public source · historical
CurrencyTypically previous day · D‑1
UseSituational awareness only
Applies to GPS degradation reporting Historical D‑1 context Not real-time Not an onboard RF detector

It does not confirm that interference is present — or absent — during the flight, and does not necessarily predict what will occur.

Coming soon — in development

One flight package. Desk to cockpit and back.

Today a single departure can cost the desk an hour of assembling, emailing, chasing a signature and filing the result.

Dispatch Mode is being designed to close that loop inside one tool: operations assembles the package from the sources the company already uses, the pilot reviews and signs it, and the signed record is retained with its own trail — replacing the email, phone and paper handoffs that currently sit between the two.

  • Encrypted in transit and at rest
  • Versioned — supersedes, never overwrites
  • Not modifiable after signature
  • Traceable end to end
Time back to the deskAssembly, distribution and filing happen in one place instead of across four tools.
One channel, not fourThe package replaces the email thread, the phone call, the printout and the shared folder.
Audit trail without adminThe record is a by-product of the workflow rather than a separate filing job.

Future capability, described as designed intent. Dispatch Mode is not deployed and nothing in this section is presented as available today. Encryption, timestamping and retention behaviour are design objectives, not certified or independently assessed claims.

// 08 · Built from operational experience

Designed from the cockpit outward.

ROTORCORE exists because safety, standardisation and compliance should not depend on the size of the operator. Large fleets build bespoke systems to hold those three together. Small and medium operators carry the same obligations without the same budget.

It was started by a helicopter pilot and systems engineer working in the gap between that operational reality and generic digital tools. Every capability begins with a task the crew already performs, and asks how to make it clearer, faster and more consistent. Not another screen. One fewer.

SafetyThe same checks, run the same way, every departure.
StandardisationOperator procedures configured once and followed consistently across the fleet.
ComplianceRecords and provenance as a by-product of the workflow, not a separate filing job.
AutonomyThe cockpit does not depend on a signal. Critical information stays available offline.
