Vessel Altimeter

The Vessel Altimeter is a convoluted-working piece of machinery designed by the brilliant minds in Comta. It uses pressure and liquid temperature to automatically detect how high above the clouds it is, as the clouds being "Zeroth", or height zero. This makes the clockwork for the side flaps work automatically, depending on height. If it can't bounce sound from the clouds and back, it thinks it is on the ground, so all machinery stops working. That is then why Skyway Naval Force ships never try to travel over anything. If it is destroyed, then the works must be operated manually. Since SNF equipped their ships with more firepower than armor, the altimeter, located on the bottom, can easily be destroyed if low enough.
