How excessive am I? A tip for seagoing drone pilots

This can be a fast tip for drone pilots capturing boats. Reasonably than wanting on the display in your controller to see what altitude your drone is at, have a look at the horizon.

In case you’re photographing boats with a drone it is rather essential to know the way excessive you’re above the moist stuff. Too low and also you danger clipping a wave, not excessive sufficient and you may run into the boat you’re capturing.

My tip…

In case you can see the horizon within the body, then the place the horizon bisects the boat is identical degree above the water because the Drone.

E.g. On this shot, the Drone is simply above the peak of the Radar however beneath the highest of the Sat Com.

On this shot, the Drone is on the peak of the Anchor, possibly 2 Metres above the water.

On this shot, the Drone is on the peak of the highest of the mast.

On this shot, we’re fairly low, possibly 1.5 Metres.

On this shot the Drone is on the peak of the bottom of the Sat Com dome.

On this shot, the Drone is … Oooops.

Nah simply kidding.

When over water, it may be tough to guage your precise altitude. You possibly can use the reported altitude out of your controller however that’s measured utilizing a barometer constructed into the drone. The bottom/take off measurement is taken when the Drone is began on board the boat. Once you fly out over chilly water that barometric stress will lose its relevance to the preliminary measurement because the air density is totally different from the take-off level.

Additionally, a quantity on a display has restricted usefulness. Relative peak is the essential measure.

I hope this little tip will assist my fellow Drone pilots who could not have already been conscious of this relationship between the horizon and altitude.
