During simulation of mathematical model occuring following error

Derivative of state '1' in block 'Model/Integrator1' at time 161.23669481078912 is not finite. The simulation will be stopped. There may be a singularity in the solution. If not, try reducing the step size (either by reducing the fixed step size or by tightening the error tolerances)

Use limit output option for selecting integrator saturation limits. May be in your case, its running indefinitely.

The evolution of the states due to one or some unknown singularity-induced terms (something happened in the feedback loop, not displayed in the image) caused the system to blow up to .
Please check the Equations of Motion for the division-by-zero terms, or the logarithmic or trigometric singularities. A light aircraft probably have the mass of 5,000 kg.
