About the ATR 42-600
ATR launched its -600 program in October 2007 for the ATR 42 and the larger ATR 72. In its announcement about FAA certification, ATR described the updated flight deck with five LCD screens. The ATR 42-600 is the smaller of the two passenger models.
Seating capacity
ATR lists a range of 30 to 50 seats. Its examples include a 48-seat passenger cabin and a 30-seat passenger cabin. A separate layout uses part of the cabin for additional cargo while retaining 30 passenger seats.
Cabin layout
The 48-seat plan shows a single aisle with two seats on each side. ATR lists a 30-inch seat pitch for that plan and 34 inches for the 30-seat passenger plan. Seat pitch measures the distance between the same points on consecutive rows. Check the airline’s seat map for the layout on your flight.
How to recognize an ATR 42-600
Look for a short fuselage, a high-mounted wing and a propeller engine on each side. ATR lists the fuselage length as 22.67 meters. Earlier ATR 42 variants have a similar outline. The registration and model record give a more reliable identification.
Variants and related aircraft
ICAO assigns AT46 to the ATR 42-600 and AT45 to the ATR 42-500. The longer ATR 72-600 belongs to the same generation and uses AT76.
