Gear up

[[email protected]]

Is it possible to test the gear up alert on a L-NAV while on the ground?

The manual says it needs to think its going 25 KTS and may have a altitude setting as well.

I would like to add a test in my pre flight.

You might try (gently and carefully) pressurizing the pitot tube with a
large syringe, but that would be a big pain to do on every preflight.
You could also test the system off tow or any other time in the flight
by cracking the spoilers with the gear up.

A better solution would be to develop a habit of verifying the gear
handle is in the down and locked position before beginning your base
turn. Relying on electronic warnings can result in repair bills.
