Information
This example demonstrates the modeling and verification of the following aircraft requirement:
Requirement:
To prevent cold heat exchanger clogging, the time integral of the product of AirHumidity and MassAirFlow is limited.
This requirement can be modelled with the SignalAnalysis.TriggeredIntegrator and LogicalBlocks.LessThreshold blocks.
