On June 25, 2020, the MC-21-300 test aircraft, painted at Spektr-Avia, Ulyanovsk, returned to Ramenskoye airfield (Zhukovsky, Moscow region), where it will continue its flights under the certification test program.
The aircraft is equipped with a passenger cabin with a maximum capacity of 211 economy class seats. The salon features increased width of seats and minimum aisle width. The maximum dense configuration has been chosen to carry out certification tests of the passenger cabin, including emergency exit tests.
Currently there are 172 passenger seats, control and measuring equipment and test engineer workstations are in the cabin. Before testing the passenger cabin test equipment will be dismantled and full seat configuration will be installed.
The MC-21 has the advantage of the widest fuselage in its class. This allows customers to choose the layout with increased aisle or with more comfortable seats. In particular, the MC-21-300 maximum dense layout is designed primarily for low-cost airlines.
