New equipment at DI Khan Airport to enhance navigational capabilities
The Pakistan
Airports Authority (PAA) has successfully commissioned a state-of-the-art Doppler VHF
Omnidirectional Range and Distance Measuring Equipment (DVOR/DME) system at
Dera Ismail
Khan Airport, significantly enhancing the airport’s navigational
capabilities.
The DVOR/DME is a ground-based radio
navigation aid that enables aircraft to accurately determine their position,
bearing, and distance from a fixed reference point, thereby supporting safe and
efficient flight operations.

According to a PAA spokesperson, the project was launched in 2024 to replace the existing conventional VOR (CVOR) with a more advanced navigation system. The upgrade aims to improve aerial navigation accuracy, operational efficiency, and overall aviation safety.
The spokesperson credited the
successful completion of the project to the professional expertise and
dedicated efforts of the Communication, Navigation and Surveillance (CNS) team.
Flight inspection and calibration of the newly installed system were carried
out over the past two days and concluded successfully. Following this process,
the DVOR/DME has been formally commissioned and inducted into operational
service.
The commissioning underscores PAA’s
commitment to modernising aviation infrastructure and ensuring safe, reliable,
and efficient air operations in accordance with international standards.

The DVOR (Doppler VHF Omnidirectional Range) provides aircraft with precise bearing information using very high frequency (VHF) radio signals, employing the Doppler effect to enhance accuracy and minimise signal interference. Meanwhile, the DME (Distance Measuring Equipment) supplies slant-range distance data by measuring the time taken for radio signals exchanged between the aircraft and the ground station.
