Landing gear activation

Does anybody know whether it's possible to activate retractable landing gear using the barometer/GPS with Pixhawk?

I'd like to have my gear automatically switched into the down postion at say 5 metres above the ground when landing....

Thanks. DP

    No built in functionality for altitude based deployment right now.  If you check the wiki page there are some options for mode based deployment.  I assume you are working with 'copter, anyway.

    It is also possible to DIY it, if you are ambitious.  I don't know how hard it would be to modify the firmware, I don't know a lick of it. If someone asked me to do this for work, I would use a $10 arduino mini to listen to the RC signal and to the mavlink messages for altitude in the telemetry.  From there I would implement some logic like retract the landing gear when the switch is up, but if the altitude is less than 5 then deploy them.
