This is my personal tracking page with Delorme InReach aviation data plan.
Delorme provides:
1 minute update cycles vs. 10 for spot :-(
Airspeed - spot nada
Altitude - spot nada
Heading - spot nada
Spot is really designed for people on hikes moving slowly along in remote area's.
Delorme is better suited for aviation. They have numerous plans based on the number of hours you plan to fly. You can also change to 10 min tracking if you want to save $$$ but still get altitude, etc.
The experience of following a flight with 1 minute updates, heading, altitude and airspeed is far more enjoyable, meaningful and FUN that watching spot. My experience is that very few people even bother watching spot tracking flights because it is so boring. If we all had InReach it would be much more fun to follow along.
Just sayin...
