Overview

Summary

The G400 occupies a very strong range for those who need international autonomy without entering the brand's larger aircraft category. It delivers a balanced package between range, speed and cabin, which helps maintain an executive routine of long trips with fewer stopovers and a more constant onboard experience throughout the year.

Up to 12 passengers

The cabin configuration allows you to accommodate executive team schedules without sacrificing useful space on board.

4,200 nm range

Autonomy serves international routes with less scale dependence and more schedule stability.

Large cabin for long stay

At 1.88 m high and 2.31 m wide, the environment favors real use for work and rest.

Cabin

Space and onboard experience

In the cabin, the G400 works with measurements that make a difference in real use: 1.88 m high, 2.31 m wide and 11.07 m long. In practice, this means more freedom to move around, organize short meetings during the flight, alternate between moments of focus and rest and maintain comfort even on long legs. The configuration for up to 12 passengers allows you to adjust the aircraft for different usage profiles, from more reserved trips to schedules with reduced staff.

Performance

What the official numbers show

In reference numbers, the model combines a range of 4,200 nm, a maximum speed of Mach 0.90, takeoff at 5,000 ft, an initial cruise altitude of 41,000 ft and an operational ceiling of 51,000 ft. This set favors international travel with good time predictability and helps reduce schedule losses in operations with frequent trips.

Analysis for purchase

Reading for the purchasing executive

For the purchasing executive, the G400 makes more sense when the operation calls for intercontinental range with a large cabin, but with a more rational use structure than that of a larger ultra long range. It is an aircraft that stands out for high-frequency routines, combining competitive travel time with comfort for long trips.
