The 717 features a two-crew [[glass cockpit]] that incorporates six interchangeable liquid-crystal-display units and advanced Honeywell VIA 2000 computers. The cockpit design is called Advanced Common Flightdeck (ACF) and is shared with the [[McDonnell Douglas DC-10#MD-10 upgrade|MD-10]] and similar to the [[McDonnell Douglas MD-11|MD-11]]. Flight deck features include an Electronic Instrument System, a dual Flight Management System, a Central Fault Display System, and [[Global Positioning System]]. Category IIIb automatic landing capability for bad-weather operations and Future Air Navigation Systems are available. The 717 shares the same type rating as the DC-9, such that the FAA approved transition courses for DC-9 and analog MD-80 pilots could be completed in 11 days.<ref name="alpa">{{Cite journal |last=Rogers, Ron |date=March 2000 |title=Flying the B-717-200 |url=http://cf.alpa.org/internet/alp/2000/marb717.htm |url-status=dead |journal=Air Line Pilot |page=26 |archive-url=https://web.archive.org/web/20071215195504/http://cf.alpa.org/internet/alp/2000/marb717.htm |archive-date=December 15, 2007}}</ref>

In conjunction with Parker Hannifin, MPC Products of Skokie, Illinois designed a fly-by-wire technology mechanical control suite for the 717 flight deck. The modules replaced much cumbersome rigging that had occurred in previous DC-9/MD-80 aircraft. The [[Rolls-Royce BR715]] engines are completely controlled by an electronic engine system ([[FADEC|Full Authority Digital Engine Control]] — FADEC) developed by [[BAE Systems]], offering improved controllability and optimization.<ref name="alpa" /> The engine claimed significantly lower fuel consumption compared to others then available with the equivalent amount of thrust.<ref>{{Cite web |title=BMW Rolls-Royce Power Plant for the Boeing 717 |url=http://www.boeing.com/commercial/aeromagazine/aero_05/textonly/ps03txt.html |access-date=December 20, 2016 |website=boeing.com |publisher=Boeing}}</ref>

Like its DC-9/MD-80/MD-90 predecessors, the 717 has a 2+3 seating arrangement in the main economy class, providing only one middle seat per row, whereas other [[narrow-body aircraft|single-aisle]] [[twinjet|twin jets]], such as the [[Boeing 737]] family and the [[Airbus A320 family]], often have 3+3 arrangement with two middle seats per row.<ref>{{Cite web |title=717-200 Seating Interior Arrangements |url=http://www.boeing.com/commercial/717/pf/pf_interior_seating.html |url-status=dead |archive-url=https://web.archive.org/web/20011122095503/http://www.boeing.com/commercial/717/pf/pf_interior_seating.html |archive-date=November 22, 2001 |access-date=July 13, 2015}}</ref><ref>{{Cite web |title=Superior Passenger Seating Comfort 717-200 |url=http://www.boeing.com/commercial/717/pf/in_cross.pdf |url-status=dead |archive-url=https://web.archive.org/web/20011122095526/http://www.boeing.com/commercial/717/pf/in_cross.pdf |archive-date=November 22, 2001 |access-date=July 13, 2015 |website=Boeing}}</ref> Unlike its predecessors, McDonnell Douglas decided not to offer the MD-95/717 with the [[Boarding (transport)|boarding]] flexibility of aft [[airstairs]], with the goal of maximizing [[fuel efficiency]] through the reduction and simplification of as much auxiliary equipment as possible.<ref name="acaps">[http://www.boeing.com/assets/pdf/commercial/airports/acaps/717.pdf "717-200 Airplane Characteristics for Airport Planning"].
