Laversab 6300 and 6600 Pitot-Static Testers: What's the Difference?

Key Takeaways

1. Laversab's 6300 series (M3, M4, W) and 6600 series (L, NG) are both fully RVSM-compliant, automated, and designed for annual calibration – but they serve distinct aircraft types. The 6300-M3 and M4 are purpose-built for military applications; the 6300-W and 6600 series are designed for commercial, business, and general aviation platforms.
2. The 6600 series adds three-channel output and SmartProbe™ compatibility – making the 6600-L and 6600-NG the right choice for aircraft from Embraer, Gulfstream, HondaJet, Airbus, and other manufacturers that use SmartProbe air data systems.
3. Wi-Fi connectivity is available on the 6300-W and 6600-NG, enabling wireless control via tablets or laptops and reducing the need for physical connections during testing. The 6600-NG also offers an optional internal battery for 6–8 hours of portable, off-grid operation.
4. The 6300-M3 and M4 share nearly identical capabilities, with one key distinction: the M3 supports both AC and 28V DC power, while the M4 is AC-only – making the M3 the better fit for operations requiring DC power compatibility.
5. PJi offers the full Laversab pitot-static tester lineup with flexible acquisition options – purchase, rent-to-own, and one-time rentals – backed by aviation specialists who can match the right model to your fleet and maintenance requirements.

Laversab offers two popular lines of pitot-static test sets – the 6300 and 6600 series – each engineered to meet specific aircraft testing requirements. These reliable tools verify the accuracy of critical flight instruments, ensuring the safety of flight crews and passengers.

In this article, we'll provide an in-depth comparison of Laversab's 6300 and 6600 series pitot-static testers, highlighting their key features, capabilities, and suitability for various aircraft types, to help you select the right equipment for your maintenance operations.

Which Laversab Pitot-Static Tester Is Right for Your Aircraft?

Laversab's 6300 and 6600 series pitot-static testers are designed to meet a variety of aircraft maintenance requirements. Whether you're servicing commercial airliners, military jets, or aircraft equipped with SmartProbes™, these testers offer reliable solutions for accurate air data system evaluations. Here's a closer look at the specific models within each series.

Laversab 6300-W

The Laversab 6300-W is a two-channel, RVSM-compliant pitot-static tester designed to deliver precise and efficient air data system evaluations across a wide range of aircraft. Equipped with built-in vacuum and pressure pumps and emergency manual bleed-down valves, this tester ensures reliable performance for both routine maintenance and critical inspections.

A compact, lightweight remote unit allows technicians to control the tester directly from the cockpit. The remote features a large, sunlight-readable display and intuitive keypad, facilitating seamless testing of altimeters, climb indicators, airspeed/Mach indicators, air data computers, and autopilot systems. Integrated Wi-Fi enables wireless control via tablets or laptops, enhancing flexibility and reducing the need for physical connections during testing.

The "Profiles" feature allows users to execute a sequence of test setpoints using a single key on the remote unit, streamlining the testing process and improving efficiency. Meeting the latest RVSM requirements, the 6300-W requires calibration only once a year, minimizing downtime and maintenance costs.

Laversab 6300-M3

The Laversab 6300-M3 is a robust, two-channel, RVSM-compliant automated pitot-static tester specifically engineered for military and defense aviation environments. It supports comprehensive evaluations of altimeters, airspeed/Mach indicators, vertical speed indicators, air data computers, and autopilot systems, and operates reliably across a broad temperature range, making it suitable for a wide range of military applications.

A compact, lightweight remote control allows technicians to operate the tester from the cockpit, displaying critical parameters such as altitude, climb rate, and airspeed. Built-in vacuum and pressure pumps with a membrane dryer deliver clean, dry air for accurate system performance, and manual bleed-down valves ensure safe depressurization in the event of power loss.

The 6300-M3 stores up to 20 profiles, each containing up to 50 setpoints, and can be executed with a single key on the remote – and "Jog" functionality allows incremental set-point adjustments for added precision. Annual calibration keeps maintenance downtime to a minimum. The unit supports 90-260V AC (47 to 440 Hz) or 28V DC power sources, accommodating diverse operational environments.

Laversab 6300-M4

The Laversab 6300-M4 shares the same core architecture as the 6300-M3 – including RVSM compliance, built-in pump and membrane dryer, Profiles and Jog functionality, cockpit remote operation, and annual calibration – but is specifically engineered for higher-performance military applications, including fighter and attack aircraft. The primary distinction is its power compatibility: the 6300-M4 supports only 90-260V AC (47 to 440 Hz), without the 28V DC option available on the M3. For operations requiring DC power compatibility, the 6300-M3 is the appropriate choice.

Laversab 6600-NG

The Laversab 6600-NG is a versatile, three-channel, RVSM-compliant pitot-static tester tailored for aircraft equipped with SmartProbes™, such as those from Embraer, Gulfstream, HondaJet, and Airbus. Its three outputs – primary static (Ps1), pitot (Pt), and a configurable third channel (Ps2) that can simulate angle of attack (AOA) or angle of sideslip (AOS) – provide the flexibility needed across a wide range of testing scenarios.

Technicians can operate the unit from the cockpit using a compact remote that displays altitude, climb rate, and airspeed. Built-in vacuum and pressure pumps, along with emergency manual bleed-down valves, ensure reliable performance during routine and critical inspections alike. Wi-Fi connectivity enables wireless operation via tablets or laptops, and the Profiles and Jog features support streamlined, precise test execution.

The 6600-NG supports 90-260V AC (47 to 440 Hz) power and offers an optional internal battery providing 6–8 hours of operation for added portability. With annual calibration as the only scheduled service requirement, the 6600-NG is an efficient, low-maintenance solution for testing air data systems on modern commercial and business aircraft.

The Bottom Line

Whether you're maintaining commercial airliners or military aircraft, selecting the right pitot-static tester is crucial for ensuring accurate air data system evaluations. Laversab's 6300 and 6600 series offer reliable, RVSM-compliant solutions tailored to a wide range of aircraft requirements.
