The variometer on the right is from the world of hang gliders and sailplanes. It serves as altimeter, speedometer, and rate-of-climb indicator. Here, I'm at 5,003 ft. above sea level. My airspeed is 54 mph, and I'm climbing very slightly. I can tell that because the black bar on the left is above zero. The number 0.4 says that my time-averaged rate of climb is 40 feet per minute.

The GPS unit is aimed at the Harford Airport, which is dead ahead (the red arrow is straight up) and 7.02 statute miles away. My current ground speed is 52.0 mph. At this rate, I'll arrive at Harford in 12 minutes and 13 seconds. Oh, and my compass heading is about 78 degrees, so my GPS is my compass. But I never use compass headings. Instead, I use the GPS, and after that, the chart in my kneeboard. As Hugh says, I fly IFR - not instrument flight rules, but "I Follow Roads."
