Final answer:
The full alignment process for the INS in the EGI typically takes around 14 minutes. During alignment, the INS uses information from sensors to establish a precise reference frame. The alignment time may vary depending on the specific INS model and the desired level of accuracy.
Step-by-step explanation:
Inertial Navigation System (INS) is an advanced navigation technology used in aircraft and spacecraft. The alignment process in an INS is essential for accurate navigation. In the Enhanced Ground Interface (EGI) system, a full alignment typically takes around 14 minutes. During alignment, the INS uses information from various sensors such as accelerometers and gyroscopes to establish a precise reference frame.
This allows it to determine the aircraft's position, velocity, and attitude. The alignment time may vary depending on the specific INS model and the desired level of accuracy. For example the Honeywell LASEREF IV INS commonly used in commercial aircraft, typically takes approximately 14 minutes to complete a full alignment. However newer technologies such as Global Navigation Satellite Systems (GNSS), have reduced alignment times even further.
