Re: Flat Earth
My kit is slightly below sea level, just like the ground floor of my house. More importantly, computer manufacturers have been asked in the past to recertify their products to guarantee it from somewhere like 10 meters below sea level to their current maximum height above sea level, just to secure an order from Schiphol (Amsterdam Airport) as it is at minus 7 meters. Luckily for most pilots, air planes mostly use radio altimeters now.
