AVIATION / Avionics & electrical / REVIEWED 2026-09-11
Observe weather ahead of the aircraft.
Weather radars compare by detection mode and installation as well as range. Weather returns, turbulence detection and windshear functions have different limits.
Program applicability is stated for each listing. 737NG, 737 MAX, and other aircraft examples are distinct configurations; listed products are not automatically interchangeable or approved for installation.
Airborne weather radar detects and prioritizes convective hazards; numerical example refers specifically to the WXR-2100A sheet. [1][2]
Contact the manufacturer or aircraft OEM for the applicable approved program and configuration. This is an inquiry route, not an assertion of stock, price or installation eligibility.
Automatic volumetric weather radar for business-aircraft installations. [3]
Other aircraft — business aviation; no 737 fit established [3]
Contact the manufacturer or aircraft OEM for the applicable approved program and configuration. This is an inquiry route, not an assertion of stock, price or installation eligibility.
Solid-state Doppler weather radar with installation-dependent display integration and optional turbulence functions. [4]
Other aircraft/retrofit candidate; no 737 applicability established [4]
Contact the manufacturer or aircraft OEM for the applicable approved program and configuration. This is an inquiry route, not an assertion of stock, price or installation eligibility.
A company address is shown separately from a published factory location. Request the manufacturing site and lot traceability for the exact part when sourcing.
Aperture, scan clearance, radome loss and mounting determine performance.
Specify mode and target/precipitation conditions rather than equating display range with guaranteed detection.
Compare each hazard function separately, including optional features.
Horizontal/vertical coverage and automatic tilt affect workload and coverage.
Heavy precipitation can obscure weather farther away.
Verify compatible buses, screens, dual-pilot modes and software.
Transmitter power differs from total electrical consumption.
Review antenna, radome and avionics changes as one installation.
Specifications belong to the named product and configuration.
Manufacturer performance statements; target and operating conditions affect actual detection.
Manufacturer pages and technical documents support the linked claims. A review date is not a publication date or stock check.
