Landing gear indications

[Pobb]

I am wanting to show my landing gear indications on my EMS display. I can see what is required for gear down and gear unsafe indications, but can you advise if there is a condition that will give me no (blank) indication. I would like to use the red indication as a gear in transit warning and the blank indication when the gear is up.

This is possible, but it depends a bit on what switches or outputs you have from your landing gear system.

You can define SkyView to show red below one voltage, blank between two voltages, and green above the voltage (or any color for each range.) So what you want is an input that isn't just grounded or not grounded, but has 3 states: Grounded, not grounded, and grounded via resistor.

If you have a mechanical switch for each strut, one when down and one when up, this is easy. If you have an electronic controller, it all depends on how that output things.

Let us know what sensors you have and we can help more.

Thanks DS. I will have 2 change over micro switches which I can configure to obtain the three states needed.

I take it from the install manual that 0 to 2.5 volts will give a green indication, and 2.5 to 5 volts will give the red. You say in your post that this can be achieved using a ground/no ground/ resistive ground state, which would make the wiring much simpler than what I had planned. Which of these states will give me the colors that I require?

Thanks, Oldngrey

You can actually set the colors (red/yellow/green/black) to any 5 voltage bands between 0-5v you like (you can reuse colors). So for Example, you could have

0-1V = Black
1-2V = Red
2-3V = Yellow
3-4V = Green
4-5V = Red

just to invent an arbitrary example.

Thanks again DS.

I am just starting to get my head around how flexible this system is.
