Landing Height System (200 ft) with Gear Warning System.

In stock (can be backordered)

SKU: LHS-200-C Category:



UPDATE: Certified Airplanes can now enable callouts down to 1 ft.

Our updated FAA Certificate as mentioned in the Rev A3 Installation Guide does not limit Certified Airplane callouts.
Previous Certified Mode option that limited the callouts to 5 ft is now removed. This applies to all installed units.


This is our FAA NORSEE Certified Landing Height System with Gear Warning System.  This unit is suitable for airplane with a retractable landing gear.
This unit can also be installed on a fixed gear airplane with the Gear Warning System disabled in the Setup menu.


This Landing Height System is FAA-approved for installations on FAA-certified airplanes.

It includes a built-in eye-safe Class 1 Laser (Light Detection and Ranging) along with an audio interface system so height announcements can be heard when coming to land.

  • Aural height announcements starting 200 ft.
  • Fully enclosed unit with quick-disconnect 5-wire connector
  • An advance Audio interface that can be updated to use any language or accent if desired
  • Built-in Wi-Fi interface for Set-Up and feedback with any Phone (iOS or Andriod), Tablets, or PC/Laptops
  • Runs on both 12V or 24V Aircraft power Systems.
  • Gear Warning System with isolated input to detect the status/condition of the Landing Gear using a single wire.
  • GPS RS232 input from an external GPS


The Landing Height System offers situational awareness aid, added safety, and great advantages; especially in situations such as:

  • When being used to 50 ft wide runway then visiting a 100 ft or 150 ft wide runways.
  • Night landings especially when not current.
  • When transitioning from a slower/trainer airplane to a higher-performance airplane.


Customers actual feedback:

– Perfect when going to a wider or different width runway.

– Precise and perfect landing each time.

– Helped me a lot at night landings with my not-so-bright landing light


New Features:

LHS-200-C units includes Gear Warning System;  a physical check with a single wire that can be hooked to the gear switch/lever or to a single gear indicator light to detect if the gear is is still raised when the unit starts to detect the grounds.   Once the unit detects the landing gear is still raised, it does not announce height but keeps repeating “Check Landing Gear” every 4 seconds.  
The 200-C also includes a GPS RS232 Aviation/NMEA 0183 format input.  This input when connected to a GPS source on the airplane, will offer higher GPS reported altitude.   The 200-C uses the exact same case & laser sensor as the previous 100-B model.


This unit is approved for installation on an access panel or inspection plate internally (above the access panel; inside the wing or fuselage).  Contact us for a different unit that is approved for external installations (below an access panel or inspection plate)
