SmartPath Ground-Based Augmentation System

Honeywell’s SmartPath ground-based augmentation system (GBAS) provides a cost-effective precision navigation solution to increase airport capacity, decrease air traffic noise and reduce weather-related delays. It also reduces operating costs for both the aircraft operator and Air Navigation Service Providers (ANSP).

By providing aircraft operators with very precise, high integrity digital navigation data, Honeywell’s SmartPath GBAS provides unparalleled flexibility to terminal operations that enables ANSPs to efficiently manage airspace in ways that were not possible with legacy instrument landing systems (ILS).

Honeywell’s SmartPath GBAS is the world’s only certified satellite-based navigation and precision landing system.
The current SmartPath SLS-4000 GBAS is certified to Category I (CAT I) precision landing. The SLS-4000 CAT I system available today has a defined technical solution that will meet the requirements for CAT II/III GBAS.

Frequently Asked Questions

What is the typical lead time for gas turbine overhaul services?

The lead time for gas turbine overhaul services ranges from 6 to 14 weeks, depending on the damage assessment, parts availability, and whether hot-section repairs are required. Expedited options may reduce this by 30%.
Do you provide customizations for legacy turbine control systems?

Yes, we retrofit legacy systems (e.g., GE Frame 5, Siemens V94.2) with modern digital controllers, typically completing hardware integration within 4-8 weeks. Software migration requires additional validation time.
How often should industrial gas turbines undergo performance testing?

We recommend annual performance testing under ISO 3977-2 standards. Critical applications (e.g., offshore platforms) may require semi-annual tests with emissions compliance checks.
Are your radiation-hardened (rad-hard) semiconductors compliant with MIL-PRF-38535?

All rad-hard devices (e.g., FPGA, ADC) are QML Class V certified under MIL-PRF-38535 and tested to MIL-STD-883 Method 1019 for SEU tolerance. Full qualification reports are available upon request.
What temperature ranges do your military-grade ICs support?

Our ASICs and power management ICs operate across -55°C to +175°C ambient temperatures, with derating curves provided in military temperature range (MTR) datasheets.
Are PMA parts interchangeable with OEM components?

Our PMA parts (e.g., actuators, sensors) hold FAA/EASA Form 1 certification and match OEM form/fit/function. Installation requires SB/MB documentation per FAA AC 23.1529.
What traceability standards do you follow for aircraft fasteners?

All NAS/MS fasteners include full DNA traceability: melt source (AMS 2301), heat/lot numbers, and AS9100-compliant MTRs with ultrasonic test reports.
How do you handle urgent AOG (Aircraft on Ground) requests?

AOG orders ship within 4 hours for stocked items (FAA-PMA, EASA Part 21G). Non-stock critical parts trigger priority manufacturing with 72-hour max turnaround.
