The most notable modern feature of the multirole helicopter GÖKBEY (T625) is located on the dashboard in front of the pilots. Analog gauges have been replaced by a fully digital glass cockpit and a domestic avionics suite based on ASELSAN. This architecture is designed to reduce workload when flying with one or two pilots and to make task data readable at a glance.

Glass Cockpit: Multifunctional Displays

Instead of mechanical needles, GÖKBEY features large multifunctional digital displays (MFD). Flight data, engine and system status, navigation maps, and mission information are layered on these screens. The pilot can rearrange the layout according to the flight phase, and critical alerts are displayed by priority. This is the essence of the glass cockpit philosophy: several large screens are read faster than many small instruments.

4-Axis Digital Autopilot

A key feature of the control system is the 4-axis digital automatic flight control system (AFCS/autopilot). The four axes cover pitch, roll, yaw, and collective (vertical axis). This allows for maintaining a set altitude and speed, while the automatic hover and approach modes ease the pilot’s workload. The digital autopilot is particularly valuable in poor visibility conditions, at night, and over water.

ASELSAN Avionics Complex

The GÖKBEY avionics are largely supplied by ASELSAN. The complex represents a domestic whole, including integrated navigation, communication, identification, and mission execution systems. Domestic avionics are important for both the security of the supply chain and reducing dependence on third-party export approvals.

Integrated Modular Avionics (IMA)

In modern helicopter avionics, there is a trend towards integrated modular avionics (IMA) instead of a separate unit for each function. Common computing resources are utilized through software-defined modules. The result is less wiring, less weight, and simpler upgrades. The contribution of domestic software developers, such as HAVELSAN, to the software base of GÖKBEY supports the resilience of this integrated architecture.

Pilot workload and task flexibility

The overall goal of the glass cockpit, digital autopilot, and integrated warning management is to reduce pilot workload. In transport, search and rescue, medical, or maritime missions, the crew can focus on managing the task rather than piloting. The ability to customize the screen layout for the task also facilitates the use of a single platform in different variants.

NOTE

The avionics configuration of GÖKBEY may vary by customer and variant; final systems are defined by contract. Some task execution systems have not yet been officially disclosed individually.
