Which of the following is a key feature of the ERJ's navigation system?

The key feature of the ERJ's navigation system is its GPS capability for enhanced route precision. The integration of GPS technology significantly improves the accuracy and reliability of navigation by utilizing satellite signals to determine the aircraft's exact position. This capability allows for more precise routing, direct flights, and efficient use of airspace, which contributes to overall operational efficiency and safety.

Incorporating GPS into the navigation system aids pilots in maintaining situational awareness, particularly in areas where conventional navigation aids may be less effective or unavailable. The advanced navigation functionality that GPS provides is essential for modern commercial aviation, as it supports various flight modes and enhances the aircraft's capability in executing complex approaches and departures.

By leveraging GPS alongside other navigation aids, the ERJ can achieve a higher level of navigational precision compared to systems reliant solely on traditional methods like dead reckoning.
