What is the recommended altitude for a typical cruising flight in the ERJ 170/175?

The recommended cruising altitude for the ERJ 170/175 aircraft is typically around FL350, which is 35,000 feet. This altitude is chosen for several operational reasons, including optimal fuel efficiency and aircraft performance.

At FL350, the aircraft is able to take advantage of more stable air and reduced turbulence, which can enhance passenger comfort and improve overall flight safety. Additionally, flying at this altitude allows the ERJ 170/175 to balance fuel burn and altitude performance within its operational limitations while meeting regulatory requirements for altitude and airspace traffic management.

Although the aircraft has the capability to fly higher, such as at FL390 or FL410, the choice of FL350 is more common for routes that demand efficient fuel use and effective route planning. Thus, this altitude represents a sweet spot that many operators prefer for maximizing efficiency during typical cruise flights.
