I was thinking how easy it would be to build
an auto land system.

Anybody know how to program Android apps?

All you need is a tablet with a USB port and moving map software.

Then you build a pressure altimeter using a single
chipper and a pressure sensor with a USB interface.

The GPS is built into the the tablet.
You set the coordinates of the end of the runway you want to land
on and that will put you within 15 feet.

The last little bit is done with a ultrasonic back up sensor.

It is not difficult to write program for Android phones up to version 2.30. I suspect Android tablet 3.0 is similar.
However, I would not use it to land. The entire system with all the other un-tested apps will be too much to be able to guarantee stability.

Instead, I would build a standalone auto-land system and use the tablet as Human Interface Device to present the data.

Are you building a rotary powered airplane Henry? If so are you planning
on buying Tracy's EC and EM?

Is there an app interface call for the UPS port in 2.30?
