Hello,

Is anyone FPV'ing and using Video Glasses or a monitor with an Artificial Horizon ?

I would like to have something which shows attitude on the monitor while flying.

If so, what are you using ?

Thanx.

peoples don't use artificial horizon because they have the real horizon in front of the eyes. No one fly fpv in cloud for long period or in the night, we prefer sunshine :)
to have altitude many osd are available.

Intelligent Flight is working on one that will interface with their DragonOSD. They're in the development/design stage now.

So, people are not loosing orientation when flying ?
Are they using wide angle lenses on the cameras ?

People tend to lose orientation with where they are flying from, and can't work out how to get back, rather than seeing the horizon.

Horizon is super easy to find, If you see sky, nose down, if you see ground, pull up :) OSD's are there to help you find your way home safely.

It's common to think we lost orientation while flying for people who never tried it, but imagine yourself 100 to 400ft from the ground, you will see the landscape, you will see everything the same but on another angle, you have no reason to lost orientation.
Sure if you take-off and go in straight line and begin to think where you are 5 min later, you will be lost. But normally when you are not familiar somewhere, you go progressively to explore and come back rapidly.
In seven years of flying, it happen to me only one time I was lost for around 30sec. but I take time while turning and finally see something that help me to know where to go. If I had not know where to go, I would land there, and watch the video in playback to understand in which direction I gad gone and where I land.
When you learn to fly like in a real plane, you don't use anything other than your eye and horizon, forgot osd at first, you will need osd with return home feature when you will go beyond 1km, inside this range you will easily recognize your landing spot aera.

It's still a good idea to familiarize yourself with the flying field. You CAN get lost. It does happen to people that jump into FPV and are not prepared. The best thing to do is to look at your flying field using Google Earth. Study all of the terrain features (trees, roads, buildings, etc.). Then you will be much more prepared. Also keep in mind that you will have a lot smaller field of view than if you were actually in a real airplane. Your eyes have about 180 degrees of view without turning your head. This is much more than you will see through the camera, which will be closer to 90 degrees. Using a wide angle lens will definitely help.

Has anyone else encountered a 'phase change' at about 600 ft?
Below this, it seems easy to stay orientated, have a 'feel' for where one is.
Above this, suddenly you feel you are 'up in the sky', the ground can appear to drift slowly by or even feel as if it has stopped moving.

It probably varies with the field of view, but I'm impressed (and made anxious!) by the feeling of detachment that seems to switch in.

Not really... of course the references you've used yourself to will become smaller and less apparent, but that's where you take other ones further apart and do the same ;)

I look forward to having a artificial horizon. I have been in clouds where it would have been very useful. I have flown at night where it also would have been very useful. In fact, I prefer to fly at night, the scenery can be much prettier!

Turbostangs reply good advice, fly around at increasing altitudes near the field and look for prominent features near the field. If you are really worried about it, keep a coloured smoke flare handy, if you get lost fire it up and look for the smoke! Good system if flying where there are few stand-out features.
