Every calibration mission is conducted under real flight conditions to ensure systems meet international regulatory standards and provide pilots with accurate guidance throughout every stage of flight.

Backed by extensive operational experience, The ACAM Group provides comprehensive support including calibration planning, compliance assistance, data analysis and detailed reporting. Our commitment to precision, reliability and operational excellence helps improve airport performance, reduce delays and enhance aviation safety, delivering trusted calibration solutions for airports, governments and aviation organisations worldwide.

ILS FLIGHT CALIBRATION

ILS flight calibration verifies the accuracy of an airport’s Instrument Landing System, a key navigation aid used during approach and landing. The system provides precise lateral and vertical guidance, helping pilots land safely in low visibility and adverse weather conditions.

Using a specialised inspection aircraft, ACAM conducts flight checks to assess signal accuracy, alignment, coverage and overall system performance. These tests ensure compliance with international aviation standards and confirm reliable guidance throughout the approach phase.

Regular ILS calibration is essential for maintaining runway safety, reducing operational risk and ensuring consistent landing performance. ACAM delivers accurate, dependable services worldwide

VOR FLIGHT CALIBRATION

VOR flight calibration ensures the accuracy, reliability and safety of one of aviation’s most widely used navigation systems. A VOR beacon provides directional guidance to aircraft, helping pilots navigate safely and efficiently throughout their journey. Using specialised inspection aircraft and advanced flight inspection technology, ACAM tests signal strength, bearing accuracy, stability and overall performance under real operating conditions.

These inspections confirm the VOR is transmitting precise radial information and meeting international aviation standards. Regular VOR flight calibration helps prevent navigational errors, improve airspace efficiency and support safe aircraft operations. ACAM delivers accurate, dependable and ICAO compliant calibration services worldwide.

DME Flight calibration

DME flight calibration verifies the accuracy and performance of Distance Measuring Equipment, which provides aircraft with precise distance information from a ground station. Using specialised inspection aircraft, ACAM evaluates signal timing accuracy, strength, coverage and reliability across different altitudes and ranges to ensure compliance with ICAO standards.

These tests confirm that distance readings remain consistent and dependable for both en route navigation and approach procedures. Accurate DME performance is essential for situational awareness, safe separation and integration with other systems such as VOR and ILS.

Regular DME flight calibration improves navigation accuracy, reduces operational risk and supports efficient airspace management. ACAM delivers precise, reliable calibration services worldwide.

radar flight calibration

Radar flight calibration ensures the accuracy and integrity of surveillance systems that track aircraft in controlled airspace. Primary and secondary radar provide air traffic control with real time position, altitude and identification data. During calibration, ACAM uses specialised aircraft and advanced instrumentation to test coverage, detection accuracy, signal timing and reliability across multiple headings, altitudes and distances.

These checks confirm that radar returns match the aircraft’s true position, supporting safe separation and efficient traffic flow. Regular radar calibration helps identify blind spots, validate system performance and ensure compliance with aviation standards. ACAM delivers precise, reliable calibration services worldwide.

Frequently Asked Questions
