Aural Null Simulator Screen Shots

Here are some screen shots of SARMobile.Ca AirNav program running in Aural Null simulator mode. This is an Aural Null Procedure A which took about 1 hour 20 minutes to complete from first detection of the ELT until overflight of the computed location.

The magenta circles are the aural null detection points captured as the ELT signal is first heard. The green squares are convenience way points marked when the signal is lost. This just allows for planning the turn to re-acquire the signal and capture the aural null point.

The simulated ELT was at N 45 10 W 76 20, and here is the Aural Null calculation screen showing a 2dRMS of 0.11 nm:
