Head Up Guidance

Hi folks,

I just have to show you this -real- picture.

It shows an EMJ 190 approaching London City Airport (LCY). The EMJ 190 has a special so called “steep approach capability”. The LCY airport has a 5.5 glide instead of the regular 3.5 glide. LCY is a Category C airport, meaning all pilots hve to have a simulator training in advance + a certain amount of landings in a consecutive 90 day period.
LCY has a very short runway.

In my opinion, the HUG is truly a large step to a safer way of flying. First of all, you have all the neccessary information available while looking outside!! - Second, when using it in all phases of flight, you dfinitely improve the overall performance.

Our data actually show, that using the HUG in all phases of flight improved the performance with regard to adherence to SID, STARS and -very important- the landing/touchdown footprint (1000ft point).

it is also a huge help in upset recovery (which was never neccessary to use in the real world) and in resolution advisories of the Traffic Collission Avoidance System (TCAS).

By the way, did you know, we have something like TCAS in IF too? - have a look on the map page in crowded areas:-) , you ll see a similar info like on the real world TCAS.

Safe landings,

Clipper 747PA

…well, of course you need all other instruments too and Pilots get trained to be able to fly the aircraft also without the HGS. The cockpit scan is different compared to the aircraft without HGS.

One of the biggest advantages lies in the fact, that you receive data support, while you look outside. In comparison, even on the most advanced aircraft, if you have no HGS and look out, you have no more info available than the old Charles Lindbergh (…well, maybe you do, because you can look in the direction you fly;-)

HGS is in fact an instrument, that projects every information and provides every function, that is avaiable in todays PFD (Primary Flight Display) onto the, so called, Combiner (the glass being the projection area).

If you folks would like to see or try by yourself how it works in real life, you may want to try an app by Rockwell Collins, available in the Apple App store:

HGS Flight

It is a, well rudimentary, flight simulation combined with their HGS. But its fun and you learn a lot about this powerful instrument

another picture for all EMBRAER 190 and 195 fans around.

By the way, the usage of dual HGS in all phases of flight was initially very much influenced by an US Airline: Jet Blue
They developed the advanced training methods, the operating procedures and are true Pros in this.

You can fly CAT III approaches with the HGS and auto orcmanual thrust.
You do not need the autoland function in the autopilots.

From the economical standpoint, most airlines decide between HGS or Autoland. While both features are comparable in cost, the autoland function is used quite seldom (depending in which region of the world an airline operates), while they use the HGS in all phases of flight (…as mentioned before)

It is a very clever example of a powerful and reliable man machine integration.

Happy Landings



HGS Flight is an interesting app. The HUD symbology is very intuitive and easy to fly, but those approaches are really steep! I know that is an issue unrelated to the HGS, but I wish they would fix that.
