New Cessna Citation Latitude Features Stand-Up Cabin
By J. Mac McClellan, Director of Publications, EAA 747337
The Cessna Latitude is placed squarely between the longer-range Sovereign and the smaller and shorter-range Citation XLS+.
The G5000 system features three 14-inch screens that can be “windowed” into several partitions.
The standard interior measures more than 16 feet long and a flat cabin floor with 6 feet of headroom in the center.
October 10, 2011 – On the opening day of the NBAA convention in Las Vegas, Cessna announced development of a new Citation that will have the company’s first stand-up cabin with a flat floor. The new jet is named the Latitude.
Cessna’s two largest cabin jets, the Ten and Sovereign, have dropped aisles with about 5 feet, 8 inches of headroom. The new Latitude will have a flat cabin floor with 6 feet of headroom in the center.
The Latitude is a derivative of the Sovereign using essentially the same wing and tail sections, and retaining the same primary systems. At the announcement Cessna had not selected an engine for the Latitude but overhaul interval targets for the engine are 3,000 hours to hot section inspection, and 6,000-hour TBO. Pratt and Whitney PW306C engines power the Sovereign and do have a 6,000-hour TBO.
The Latitude will have Garmin’s new G5000 avionics system that has also been selected for the Citation Ten now in development. The G5000 system features three 14-inch screens that can be “windowed” into several partitions. The G5000 is controlled by four touch-screen units with two each in the center pedestal and one each on the outboard corners of the instrument panel. Each touch-screen unit can control all avionics functions so both pilots can always reach a touch screen with either hand.
Cessna expects the Latitude to have a full fuel payload of 1,000 pounds and an NBAA maximum range with four passengers of 2,000 nautical miles. The maximum operating altitude will be 45,000 feet, but in another Citation first, the cabin altitude at that flight level will be 6,000 feet instead of the 8,000 feet the rules allow.
The Latitude maximum cruise speed goal is 442 knots at an altitude of 35,000 feet, and time to climb to 43,000 feet is targeted at 23 minutes. The airplane can continue the climb without stepping all the way to 45,000 feet under ISA conditions. Maximum weight takeoff runway requirement is planned for 3,900 feet.
The standard interior for the Latitude includes six passenger chairs and a two-place divan directly across from the entry door. The passenger cabin is just over 16 feet long with a large lav at the rear. The external baggage capacity is approximately 100 cubic feet, similar to the baggage room in the Sovereign.
Another first for Citation on the Latitude will be a powered airstair door. But the airplane will retain the fully mechanical flight controls of the Sovereign, along with the same electrically powered wing flaps. The only hydraulically operated surfaces are the spoilers and speed brakes.
The Latitude wing will have the same 16.3-degree leading edge sweep used on the Sovereign along with a straight trailing edge. At 72.3 feet, the wingspan - including new winglets - on the Latitude will be about 9 feet greater than the Sovereign. The Latitude will need a new wing-to-body fairing to account for the larger fuselage tube diameter, which will be one of several critical areas to control drag.
Base price of the Latitude is set at $14.9 million in 2011 dollars, placing the cost squarely between the longer-range Sovereign and the smaller and shorter-range Citation XLS+. Cessna is offering a million bucks off the price for initial orders.
Cessna has set an ambitious schedule for Latitude development since the program was given the green light just a few weeks before the announcement. First flight is set for the middle of 2014, certification a year later, and entry into service in the second half of 2015.
