Read in an interview with Norwegian ceo Bjørn Kjos in Norwegian finance Magazine Kapitial 16 (September 26, 2013) that Norwegian is the only airline in Europe with GLS:

"We are the only airline in Europe that can create our own glideslope and fly in automatically on handsfree We were offered the GLS system free from Boeing when we ordered aircraft because the manufacturer wanted to test it out"

Sounds great

Anyone know how this system works ?

Wich Norwegian aircrafts have this installed or is about to get this installed ?

What other airlines have it ?

GLS stands for GPS Landing System. It can be used for approaches, but not for landing.
Look at this

This is quite common in the USA, but not in Europe. In Europe the ILS system has been in use for 60 years, and is fitted to all large and medium airports. If you fly a major airline like SAS or BA, 95pc of landings in Europe are on ILS. The exception is the BA A320 fleet which has MLS Microwave Landing System at LHR which is more accurate and stable than ILS.

In the USA where airliners fly into quite small airports then GLS has caught on because the airfield installation is zero for an approach, and very little for an autoland.

So Norwegian has got GLS fitted to its Boeings, but it is of little use unless they can convince people to install the Differential GPS system referred to in the link.

Respectfully, not sure where you are getting your information as it is not totally correct.

In the U.S. there are very few airports that have GLS approaches charted for public use, the two that come to mind are EWR and IAH. Scroll down to the instument procedures part of these links:



Having been fortunate to be involved in the GLS project at IAH a few years ago, there have been issues with GPS jamming at EWR which delayed the program implementation while working on solutions so the ground station would not go off line. This mades siting the ground station at IAH very important and the first GLS approach to IAH was finally flown with a United sCO B738 or B739 in April.


The GLS approaches at these two airports only have landing minimums similar to CAT I ILS procedures and autoland is not being done last I knew.

There are more and more aircraft being delivered with the capablilty of having a receiver capable of tuning the GLS frequency, but the number is quite small yet growing with new deliveries.

Any views shared are strictly my own and do not a represent those of any former employer.
