LPV-Approach Solution for Boeing 737-NextGen

Benefits

Contact us
Enhanced Availability

Protects scheduled service between city pairs when ILS is out of service or unavailable. Greater runway coverage than ILS.

Stability and Precision

Offers a more stable approach to CAT-1 minima than ILS. LPV minimums are consistently lower than RNAV (Area Navigation) minimums.

Versatility and Robustness

Supports RNP and RNP AR approaches, making it adaptable to various operational scenarios, theoretically capable of a rock-solid glide path up to 80 miles from the landing runway threshold.

Adaptability

Displays an ILS look-alike interface, simplifying crew interaction requiring minimal training.

Additional Benefits
  • No additional fuselage penetration or OEM software required.
  • Interoperable with EGNOS, WAAS, etc.
  • Does not require replacement of MMR.
  • Readily interfaces with any other existing aircraft system (Transponder (ADS-B), HUG, CPDLC, EGPWS, etc.)

SBAS Landing System for Boeing 737-Classic

Logic Air’s STC integrates renowned CMC’s CMA-5024 GPS/SBAS Landing System Sensor Units and CMA-5025 SLS control panels (or Gables’ Touch DU – EASA 10075510) with the aircraft systems (FMS, EFIS and DFCS) to provide operational and safety benefits of Localizer Performance with Vertical Guidance (LPV) fully coupled precision landing capability.

This system can be implemented in two parts

GPS / RNP

Introduces the GPS sensor units with the required interface to the aircraft systems (IRS, ADC, FMS, EGPWS and Transponder (ADS-B)) for RNP 1/RNP 0.3 operation.

SLS / LPV

Provides GPS precision landing capability in an ILS look-alike format, requiring minimal crew training.

Introduction of 2nd Flight Management Computer for Boeing 737-Classic

Logic Air’s STC adds a 2nd Flight Management Computer (FMC) to a non-2nd FMC-provisioned aircraft; the installation is fully integrated with all aircraft systems and coupled with the F/D and A/P for LNAV/VNAV.

Logic Air’s installation kit is complete and reconfigures the existing FMC into FMC-L and introduces FMC-R (in E1-2 shelf). Furthermore, this installation conforms to the Boeing Airplane Flight Manual, so crew training is not required.

Versatility

Dual FMC greatly improves the aircraft’s versatility, meets the requirement of RNP 4, RNP 2, RNP 1, RNP APCH, RNP AR (per SL-02-025-D).

Adaptability

Designed to accommodate provisioned or non-provisioned aircraft. No additional software and/or Service Bulletins are required.

Enhanced Opportunities

Dual FMC is required for transoceanic/extended over-water operation.

Additional Benefits
  • Increases the aircraft’s dispatchability
  • Retains navigation capability in the event of first FMC failure
  • Simplifies CAA issuance of RNP 1/RNP 0.3 operational certificate
  • Enhances aircraft value (imparting it with identical operational performance to newer generation aircraft, when coupled with Logic Air’s GPS STC)
The Logic Air team has constantly exceeded our expectations in answering all GNSS (GPS) System. The selection of the right GPS system is complicated and requires absolute attention to details; accurate and timely advice – especially with the RNP System; and the Logic Air team made it simple and easy for us. The effective coordination with Logic Air team especially Linnea and Alain in overcoming the unexpected challenges, and providing real time solutions were the key success factors to the timely installation of GNSS System on our Boeing 737-300.
