PlanePlotter Mode-C window

The Blue Angels were performing here in Grand Junction over the past weekend. I took a few screenshots of the performance on the PlanePlotter Mode-C altitude window. You can see the altitude trace in green near the bottom of the 3 screens between 5,000 ft and 15,000 ft. The Grand Junction airport is at about 4,800ft MSL.

These are great posts ....and demonstrate the much under used facility in PlanePlotter which allows us to track the profile of anything sending Mode A/C within range of our receiver

A few weeks ago we had a B2 depart the UK after appearing at the Fairford airshow.
He was of course flying without his Mode S switched on....but the instant he sent a Mode A sqwk it was possible to get a brief fix on his position
The B2 only cycled his sqwk for a very short time , but enough for Beamfinder Plus to grab him.



Regular visitors to the UK are U2s on rotation.
About 50% send Mode S , the others don't


Here;s the descent profile of a U2 descending from 60,000 feet within range of my receiver , no mode S .....his trace is hilighted...
