GLS Approach Tutorial by Real 737 Captain | ZIBO MOD 737 | X-Plane 11

[@Fabi_Hansi92]

Very nice tutorial as always :) I'll try to give some insight on the GBAS approach as I remember from my ATPL theory studys. Normal GNSS guidance isn't precise enough for precision approaches since the satellite signals are suffering from ionospheric delays, multipath reception errors and also other factors. The ground based augemantion system (GBAS) which is installed on the ground close to or at the airport "knows" its own exact position (in terms of coordinates) since it is stationary on the ground. It also receives the GNSS signals (just like the aircraft) and thus can compare the calculated position from the GNSS with its known exact position. Thus it is able to calculate the GNSS position error in the vicinity (which again is caused by various factors like ionospheric delays which vary with time). The position error is then being sent to the aircraft which uses this information to greatly improve the GNSS accuracy and allowing for precision approaches. So the GBAS station actually doesn't send any real guidance to the aircraft (like an ILS would) but rather correction signals regarding the GNSS accuracy which I think is really cool :) Hope it makes sense and keep up the awesome work!

Very nice Fabi! We didn't even cover the topic when I studied for my ATPL theory all those years ago, we were still being taught LORAN-C! FD2S

[@KEITHGEE1000]

Great stuff as always. Your tutorials have become so polished as you have gained experience in the IT and presentation areas. (They were great when you first started!). Maybe it’s time to consider pulling all tutorials into a bespoke series for the B737 (as some have done for other types). It would provide an ready reference for all aspects. Be more than happy to pay for such a product. Lockdown here for a while longer, sadly.

6:38 What does the green circle on the ND mean? I've see seen multiple times in your videos, but I still don't know what it means and how to activate them... Thanks for the Tutorial mate!

[@flightdeck2sim]

Hi Major, Those are fix rings which you enter in the FIX page of the FMC, we use them to increase our situational awareness and we have company specific SOP's regarding its use., this one is based off the landing runway (RW27) X1 x3 Altitude Ring. We multiply our CRZ by x3. E.g. If cruising at FL370 we'd have a 111nn ring, this roughly will correspond with TOD X1 10nm ring. The latest point at which we can select Flap 1 X1 4 or 5nm ring. The point at which we select Gear Down, Flap15. FD2S

[@michals7650]

Once again a great tutorial!!! Just an idea for the next one maybe RNAV on A300?? It is much more complicated than on 737 or a320, quite a lot of fun actually if you are doing it right, would really appreciate some of your guidance :)

[@flightdeck2sim]

Great suggestion! For the A300 you want to be selecting V/S as the pitch mode and NAV for lateral guidance, you need to make sure you're using LNAV minima. FD2S

Amazimg video and turorial. I like your kind of turorials and videos very much! Since when has the feature of GLS/GBAS been implemented in Zibo Mod?

[@tomstravels520]

For some time now

[@pseudoAndy]

Cool. For some reason I've always thought that a GLS approach was just a 'subcategory' of an RNP approach, but I see that in Bremen there is actually a separate chart for that. Now at some airports there is no published GLS chart, but there is an option to tune an EGNOS channel during an RNP approach (e.g. CH 41194 for RWY27 in Bremen, which is different to the GLS one). Is there any difference in terms of PFD indication/guidance and would you still arm the APP mode in such case or use the LNAV/VNAV mode as usual?

[@flightdeck2sim]

Hi Ondřej! EGNOS is associated with RNP Approaches which use LPV minima. That system improves the accuracy and reliability of GPS information by correcting any signal errors from GPS using a Satellite Based Augmentation System (SBAS) and you use the MMR to tune. This approach in this tutorial is a GLS approach which uses a Ground Based Augmentation System (GBAS) which is accurate enough to provide a precision approach, again you use the MMR to tune. At my operator we don't have approval to fly RNAV approaches with LPV minima but we can fly the same RNAV approach using LNAV or LNAV/VNAV minima. With regards to arming APP on an RNAV approach this is for aircraft fitted with the IAN (Integrated Approach Navigation) mode, our fleet are not fitted with this option. You can arm APP I believe in this case the PFD will annunciate G/P (glide path) instead of G/S (glide slope). Flying IAN requires proper equipment and approval. FD2S

[@pseudoAndy]

@@flightdeck2sim Such a detailed answer, thank you so much!

[@maffie587]

Morning. Could you please explain (maybe as a video) why a certain chart is chosen for an approach over another. It's difficult choosing between X,Y,Z, RNP, GLS, NDB, and probably others I have missed. Flying TNCM/MDPC/TNCM I'm spoilt for choice.

[@tomstravels520]

Apparently the general rule is Z is used most commonly but if the direction you are approaching from isn’t supported by that chart than you’ll go off the one that does

[@LaurenV2500]

I flew the RNAV for 35 into Porto yesterday and noticed a similar but much higher 5 digit number-92423-labeled EGNOS; I tuned it but used LNAV/VNAV like a regular RNP; could I I have used it with final app since it was tuned, making it akin to a GLS? If not, what would be the purpose of tuning it into an MMR?

[@tomstravels520]

That would probably be to get LPV (Localiser Precision with Vertical guidance) minimums. If you look at the minimums on the chart if there chart has a 5 digit WAAS code then you can use that and you can get a lower minimums as it’s using satellite based correction data. That’s still not a precision approach though and I don’t know too much about the difference between LNAV/VNAV minima and LPV

[@manuelbranquinho6649]

Great video, just one question is it ok to intercept the glide path below the FAP altitude? I understand that in this case under radar control and above MSA obstacle clearance is not an issue but procedure wise is it ok? Thank you for those very educational tutorials, keep up the great work.

[@flightdeck2sim]

Hi Manuel! Well spotted and you're absolutely right, if flying procedurally you cannot descend below 3000ft until passing ROGBO, under radar vectors ATC could vector you to a shorter final and descend you below the FAF under radar control. FD2S

GLS equiped 737 is using BARO VNAV ? I m asking because in real life I have never flown GLS(always LNAV/VNAV)

[@flightdeck2sim]

Hi Samuel, the approach in this tutorial is a GLS approach which uses a Ground Based Augmentation System (GBAS) which is accurate enough to provide a precision approach, you use the MMR to tune. You use APP to fly and to the pilots it appears as a normal ILS BARO VNAV (VNAV) is used to fly RNP approaches to LNAV and VNAV minima, you use VNAV. RNP Approaches can also use LPV minima. To fly to LPV minima the aircraft must be fitted with the IAN (Integrated Approach Navigation) mode, our fleet are not fitted with this option. You can then arm APP and the PFD will annunciate G/P (glide path) instead of G/S (glide slope). Flying IAN requires proper equipment and approval. FD2S

[@WWMDandother]

In general, this method of landing is no different from a manual approach. You simply fly the course entered in the flight plan, and when you reach the glide path, maintain the required altitude and speed, and then approach in full manual mode. The GLS is here as a distraction and has nothing to do with it. In Zibo, the GLS approach was implemented extremely poorly.

Try recording a full landing and then voice overing it and pausing it it would be better I think if you don't do it already 😂
