About the ATR 42-300
The first ATR 42-300 flew from Toulouse on August 16, 1984. Certification followed in September 1985, and Air Littoral received the first production aircraft later that year.
Seating capacity
ATR’s specification sheet lists 48 seats for the standard ATR 42-300 configuration. The seat count on a particular flight depends on the cabin fitted by the operator.
Cabin layout
The standard diagram shows one aisle with two seats on each side. ATR lists a 30-inch seat pitch for this arrangement, measured between the same points on consecutive rows. The diagram also identifies exits, a galley and a lavatory. Consult the operator’s seat map for the layout on your flight.
How to recognize an ATR 42-300
Look for a high-mounted wing with one propeller engine on each side and a short fuselage. ATR lists the length as 22.67 meters. Other ATR 42 variants share the overall silhouette, so use the registration and model record to confirm the series.
