AHRS functionality is part of the sensing architecture used by the Intuos IFU.- Airworthiness Directive (AD)A mandatory instruction issued by an aviation authority to address an unsafe condition affecting an aircraft, engine, propeller or component. The Manager© supports AD/SB compliance tracking and planning.- AOG (Aircraft on Ground)A status indicating that an aircraft is unavailable for operation, often because of a technical issue or required maintenance. Condition monitoring can help reduce the risk of unplanned AOG events by providing earlier visibility into developing anomalies.- Audit-Ready ComplianceAn operating state in which records are structured, current and readily retrievable to support regulatory audits and compliance reviews. Intuos supports this through its CAMO & Maintenance and flight-school solutions.- Aviation-Grade PrecisionA positioning term used to describe data quality and sensing performance intended for professional aviation use.

Intuos' eTL is part of The Manager© operations suite.- Engine Fault DetectionThe process of identifying abnormal engine behaviour or degradation before it results in operational failure, performed acoustically by the Engine Monitor Unit.- Engine Vibration AnalysisThe measurement and interpretation of engine vibration patterns to detect early mechanical wear or imbalance, captured by the AEM's accelerometer sensors.- Envelope Warning / Flight Envelope LimitsAn alert generated when monitored flight parameters approach or exceed configured operational thresholds. These thresholds support safety monitoring but should not be interpreted as a replacement for certified aircraft warning systems.- FDM (Flight Data Monitoring)The systematic collection and analysis of flight data to identify events, trends and operational risks and support safety improvement. The InFlight Unit enables flight-data monitoring capabilities for general aviation.- First-Time Pass RateThe percentage of students who successfully pass a check, test or exam on their first attempt. Intuos' data-driven training tools can support monitoring and analysis of this training KPI.- Fleet UtilizationA measure of how effectively available aircraft hours are used relative to their operational capacity, tracked and optimised through The Manager©.- Flight Data Monitoring DeviceHardware that captures in-flight parameters such as position, attitude and acceleration for safety and training analysis, such as the Intuos Inflight Monitor Unit.- Flight School DigitalizationThe process of replacing paper-based scheduling, logbooks and training records with integrated digital systems, the mission of Intuos for Flight Schools & Aeroclubs.- FTL (Flight Time Limitations)Regulatory or organisational limits governing flight time, duty periods and rest. The Manager© can support automated checks within scheduling workflows to help identify potential non-compliant assignments.- Ground-to-Air MessagingA secure, encrypted text communication channel between ground personnel and the cockpit, used for guidance without occupying radio frequencies - available via the Inflight Monitor Unit.- Hard Landing DetectionAutomated identification of landing events that exceed configured acceleration and/or vertical-motion thresholds, flagged for review in the IFU Safety Event Dashboard.- HUMS (Health and Usage Monitoring System)A system or approach that monitors equipment health and usage parameters to support maintenance and reliability decisions, widely used in rotorcraft and other aviation applications. Intuos' engine-monitoring approach brings selected condition-monitoring concepts to general aviation.- IFU (InFlight Unit)Intuos' plug-and-play onboard hardware device that captures and transmits flight telemetry for real-time monitoring and post-flight analysis. See the InFlight Unit for full specifications.- IMU (Inertial Measurement Unit)A sensor unit using accelerometers and gyroscopes to measure specific force and angular rate. Its measurements are processed as part of the InFlight Unit's attitude and motion estimation.- Instructor AlignmentThe process of standardising teaching techniques and evaluation criteria across multiple instructors within an organisation, supported by Intuos' instructor analytics.- Life-Limited Parts / Serialized Component TrackingThe practice of individually tracking aircraft components with a fixed service-life or serial number. The Manager© manages this through a dedicated inventory and spare-parts module.- Machine Learning Engine DiagnosticsThe use of machine-learning techniques to analyse engine acoustic, vibration and operating patterns and identify deviations from expected behaviour, supporting the Engine Monitor Unit's diagnostic capabilities.- Mission Real-Time OversightContinuous situational awareness of an aircraft's status and position during high-stakes commercial missions such as Medevac or SAR, delivered to Commercial Operators via the IFU.- Multi-Base SchedulingThe coordination of aircraft, instructors and bookings across multiple operating locations from a single system, a core capability of The Manager©.- Native Integration (Zero-API)Intuos' architecture principle whereby its hardware and software components exchange data natively, reducing manual data entry and the need for customer-managed third-party API configuration within the Intuos ecosystem.- Non-Scheduled Commercial AviationCommercial air operations conducted outside a fixed published schedule, including certain charter and special-mission operations. Requirements vary by jurisdiction and type of operation; this is a segment addressed by Intuos for Commercial Operators.- Objective Flight DebriefingA training review method based on recorded flight data rather than instructor memory, improving accuracy and consistency - enabled by the Inflight Monitor Unit's 3D replays.- Part-ATOEASA approval framework for an Approved Training Organisation authorised to provide specified pilot training courses.

It defines organisational and management requirements for continuing airworthiness activities, supported by Intuos' CAMO & Maintenance solution.- Part-DTOEASA framework for a Declared Training Organisation, allowing certain pilot-training activities under a declaration rather than an ATO approval. These activities are supported by The Manager© training modules.- Pilot LogbookA record, physical or digital, documenting a pilot's flight hours, routes and qualifications - digitised as part of The Manager©.- Piston Engine DegradationGradual mechanical wear affecting a piston aircraft engine's performance and reliability over time - the primary condition the Engine Monitor Unit is designed to detect early.- Predictive MaintenanceA maintenance approach that uses condition and trend data to identify developing issues and support earlier, better-informed maintenance decisions.

Its regulatory status depends on the applicable authority and circumstances; it can be tracked alongside ADs in Intuos' CAMO compliance workflows.- SLA (Service Level Agreement)A contractual agreement defining measurable service commitments such as availability, response times or performance levels. Operational and condition-monitoring insights can help operators manage risks that may affect SLA performance.- Solo Flight SupportReal-time ground monitoring and communication support for a student pilot flying without an instructor on board, provided through the Inflight Monitor Unit.- Supplemental Type Certificate (STC)An approval for a change to an aircraft type design that is outside the scope of minor changes or applicable standard changes. Intuos devices are designed for non-invasive installation and do not require a STC; whether an STC is required depends on the aircraft, installation configuration and(...)- TelemetryData such as position, speed and attitude collected in real time from an aircraft and transmitted to a ground system, captured every two seconds by the Intuos IFU.- Telemetry ChartingGraphical visualisation of recorded flight parameters over time, used for incident investigation and maintenance planning - one of the IFU's post-flight tools.- The Manager© (Aviation Operations Software)Intuos' modular software platform for managing scheduling, training, fleet maintenance and regulatory compliance from a single system.
