Out of interest do you prefer RNAV or ILS?
If you captured the ILS and if you are correctly configured for landing it will engage the autoland modes itself.

Ok and I will not need to disengage autothrottle at all it will just automatically do reverse thrusts etc?
Sorry it is just I am so used to disengaging autothrottle and autopilot when I am near the runway threshold.
Also since this AAU2 update V1 speed doesn’t automatically alert when taking off - do you know how to set that? Would it be in FMC?
Hey, Black Cap - Both are fine and have their place. RNAV always requires a manual landing, which is great, and you can get down to essentially the same minimums as an ILS (using an LPV approach) so they are similar in profile and can be used in low visibility situations to a degree.
If weather minimums are quite low, I will typically use the ILS approach, and if visibility is essentially zero or very low, I will use a CAT III approach provided the aircraft and facility are certified (which applies to most major airports around the world). HTH!

i hope they don’t as they actually work, ok not study level but if you want that you wouldnt be buying them
Well the new AAU2 it is growing on me - lil more techy - but this is what makes us better.
I do think Microsoft will need to do a lil update for the AAU2 systems to get rid of lil approach mode bugs - an fuel bugs - however other than that it is all good!
This is a great topic/thread! I appreciate everyone’s contributions. I didn’t understand the differences between the ILS, IAN, and RNAV approaches until I read these posts. I’ve been flying only ILS approaches since AAU2. I’ll have to try both IAN and RNAV approaches.
Are RNAV/GPS approach charts used for IAN approaches? Are LPV altitudes valid for IAN approaches?
Word of advice - stick with ILS approaches with the new AAU2 update (on 747 and 787) because I have used RNAV and it is buggy sometimes it will capture the FAC (final approach cruise) other times it will not and when you press APPROACH mode button won’t capture the glidepath.
Whereas, I have used ILS a few times and it has worked perfectly.
So I think for the big airliners I will use ILS - but A320 (Asobo) will use RNAV (cos I do like RNAV approaches).
RNAV will capture perfectly (like your did there) other times glitchy you press approach and it is not capturing the FAC etc - Microsoft will need to update that I think - but considering this is the first version of this new update glitches-bugs are expected.
There isn’t any documentation I could find about the new Integrated Approach Navigation feature. After reading the posts here I tried one approach with the 787 and it worked!
The process to fly an ILS approach hasn’t changed except for autotune or manually entering the ILS frequency. Press LOC to capture the localizer and APP when entering the approach. If the conditions are met for an autoland, LAND 3 will be display in the FMA.
The process to fly a RNAV/GPS approach hadn’t changed. The LNAV and VNAV buttons should remain on.
The IAN (Integrated Approach Navigation) approach is like a hybrid RNAV and ILS approach. I used an RNAV approach initially with both the LNAV and VNAV on. The LOC button is pushed after starting the approach. It is different from an ILS approach because there is no localizer. It is actually called FAC (Final Approach Course). When armed it will be displayed in white under the green LNAV. When FAC is captured, press APP to “capture” the glide path. A white “G/S” is displayed under the green VNAV when the glide path is armed. When the glide path is captured, G/P is displayed instead of VNAV. The aircraft is now flying an IAN approach.
I tried enabling an IAN approach from a VOR-A approach but it didn’t work. A VOR-A is a “circle-to-land” approach which does not have a final approach course needed with a straight-in IAN approach.
Attached is a screenshot of how IAN approach looks. Notice the red diamonds on the vertical and horizontal tapes. Also the “green banana” shows the descent to finish right at the runway threshold.
Since there are no IAN approaches in any navigation database, I’m wondering about a missed approach. I suppose if there was a missed approach, the RNAV/GPS missed approach would be used. When ATC returns you to the airport, they are going to assign a new approach since they don’t know about any IAN.
Pink diamonds yes that is literally what the RNAV avionics looks like upon approach (if everything locks correctly as it should).
Nothing spectacular in the sense you press approach mode before reaching the penultimate waypoint before the runway.
But for me RNAV has been buggy as times sometimes locks perfectly others times not so…
For me - I will just stick with ILS approaches with the bigger birds - without hassle.
Nothing worst doing a long haul flight (setting of before going to bed or to work).
Coming back not far from destination ready to land only for the approach system to mess up and not capture what it should.
So I just stick to ILS with the giant iron birds cos that has worked 100% of the times.
I think Asobo will need to do more updates to sort out RNAV and give detailed official tutorials on the RNAV - IAN etc etc just to show the differentiation from the old system avionics to the new default avionic system that they have introduced us all to.
