Regional Jets

Regional jets are smaller commercial aircraft used for short-haul regional flights, typically serving smaller airports and connecting hubs. They have a seating capacity of around 50 to 100 passengers. Examples of regional jets include the Embraer E-Jet series and Bombardier CRJ series. The industry is supported by similar equipment and instruments as narrow-body aircraft to ensure accurate performance measurements, weight distribution, temperature control, and structural integrity.
