It would be very handy to have both low cloud level and the ground level shown at the same time. I know ground level isn’t on here yet but it should definitely be an option!
It would be very good to know that the cloud base is 3000ft approx but the ground level is at 1000ft above sea level. Therefore the difference between the ground level and clouds base is 2000ft. This would be especially important when mounting flying. Even more important when night flying.
Meaning you are still able to maintain VFR (H) flights. Especially over a long route you would be much better equipped to navigate. This obviously isn’t your primary method of navigating but it would certainly highlight a possible mistake before a flight.
