Vision is one of the most important issues in aerospace engineering. Vision technologies have major improvements in last five years. Day and night conditions of flying environment have nearly equal conditions in operations. Virtual reality technologies, which are known as flight training material, have a huge contribution to safety.
Virtual reality technologies are widely used in simulation environment of aircrafts. However, beyond training these technologies are being used as synthetic vision equipment. By synthetic vision upgrades it is possible to have synthetic safety in aircrafts.
Basic concept of synthetic vision technology uses optical flow of 3D rendered environment. This situation eliminates day and night difference and can be used during take off and landing operations. Artificially created views have immediate response to altitude, speed and angle.
You can ask if it is really necessary to have synthetic vision in aerospace engineering. The answer is yes. Accidents during take off and using new vision technologies can prevent landing. Synthetic Vision System (SVS) reduces work load of pilots. Enhancing awareness is key point in all operations of flight.
Accidents that happened because of fatal errors differ from other control accidents. Nearly all loss of control accidents happened in conditions that have no external or helpful references in aircraft. By using synthetic vision system it is possible to decrease accidents that happened after loss of control.
Optical flows of the elements in various scenes are main parts of synthetic vision technology. Natural and intuitive symbols of aviation increase safety. Graphic design and screening technology are visual side of vision technology. There are some basic standards about these systems. However commercial usage of technology in aircrafts are not common yet. It is planned to use these helpful systems in aerospace engineering through 2020.
Synthetic vision technologies are used during landing of aircrafts. But it is possible to use these concepts in guidance systems. GPS-based approach can enrich basic technology in commercial aircrafts. Nevertheless, certification of these systems is not possible. There are a lot of details that need to be considered. Due to high interest of aerospace engineering brands like Boeing and Airbus, it is not clearly approved yet.
However there are commercial aircrafts that has head up display and synthetic vision system. SVS equipped aircrafts are only allowed used in distinct area and conditions.
Hybrid systems can be next generation of navigation in aircrafts. Software based and GPS aided structure move safety to one step further in aerospace engineering.
Ultimate vision in aircraft is not dream. Night vision technologies were first step for day and night difference elimination. It is broadly used in military. But software based technologies make sense for all conditions of flight. Prototypes are successful. But HUD limitation and regulation that is related with cockpit control is not suitable. Anyway we can say that one more eye can prevent lots of things in aerospace engineering.
