There are various methods that can be incorporated for such environments such as using gyros, digital compasses or some method of inertial navigation.
Flight measurements from accelerometers and rate gyros provide airplane motion characteristics relative to axes fixed within the airframe.
Navigation is state of the art with ring laser gyros, inertial reference systems GPS, doppler and radar altimeters.
Tzatziki is a delicious cucumber yogurt sauce that is the perfect topping for Gyros sandwiches and a great dip for pita bread.
After the sauce sat for a few hours, I was able to pour it directly onto Gyros Sandwiches thanks to the pitcher's pouring spout.
