An aircraft can be anything that flies, but an airplane is a specific type of aircraft with wings that uses aerodynamic forces for flight. It is also helpful to recognize that the plural of aircraft is aircraft and never "aircrafts.". The word "aircraft" has an irregular plural, so it is both singular and plural.the astrodynamics literature as precision OD (POD). The objective of POD is to obtain an accurate orbit that accounts for the dynamical environment in which the motion occurs, including all relevant forces affecting the satellite's motion. Through this process, a preliminary orbit is estimated using a minimum number of obser-vations.Introduction.
