FWIW I've never had a problem with entry, the hold itself or exiting the hold. I did a hold over LAM approaching LHR earlier and it was fine in all aspects.

 

The approach into the LAM hold is on the same heading as a few way points behind it though. As such it's not quite the same as above (where the entry is on a different heading to the actual hold legs), though I'll agree I've never had any issues holding there either.

Have any of you tried the other two holding entries? Direct is by far the easiest. Mine can't really fly the parallel and teardrop entries. Please try those, and make sure you let it try a couple of laps after the entry.

This is weird, Just tried flying the missed apps at LEPA for RW24L, holding at MJV, direct entry, flown perfectly fine in LNAV

But RW06L, holding at CDP, I flew that missed approach twice. First try it got the holding completely wrong. Second time around flew a perfect parallel entry and followed the magenta line no problem in it's left turn

2 out of three not bad. I just go heading mode if entry starts wrong. LNAV inbound to holding fix. I saw a G1000 mess it up in a real Columbia once as well.

Very true, I didn't quite read that properly my apologies.

 

But I can reiterate that I've never had an issue with holding (yet).

Maybe, but this isn't a Columbia. I've never seen the FMC mess up holding in real life. Granted, if there is some sort of limitation, then I understand and can live with it. I know that their NG and 744 for FS9 fly them ok, so maybe it can be fixed?

 

Would be nice to have a post from the developers, maybe they are already aware of this and it is on a list for future updates or SP2?

The current track on the picture is what it flew as the outbound leg instead of the magenta line as in the FMC.

This sentence probably encapsulates a lot of misunderstanding about holding patterns and how they are executed in real life.

You are NOT supposed to follow the outbound magenta line, you only should be on the magenta line when flying inbound. The more cross wind there is the more your true outbound leg will deviate from the depicted magenta line. It is actually a very poor IFR technique if pilot would attempt to follow the outbound magenta track.

 

In short if you want to judge how well holds are executed check 1. How well the inbound leg (only inbound) matches the magenta line 2. whether turns are executed on the correct side.

 

Only during the inbound leg course is NAV-tracked, the outbound leg is always flown as a fixed heading with exaggerated wind correction. Any textbook on IFR flying describes the technique.

 

But of course, with zero wind you should be very close to the magenta line both during the inbound and outbound leg.

In short if you want to judge how well holds are executed check 1. How well the inbound leg (only inbound) matches the magenta line 2. whether turns are executed on the correct side.

 

Additionally, you should be using the Stopwatch and probably backing up with raw data to be sure you're staying on the protected side of the hold.

Hi Michael, I see what you mean, the wording in the sentence could have been better. That said, I know how to fly a real holding, and I Timed the outbound and inboubd legs, to 1 minut, but still it did not fly the correct indbound track! if flew across the indbound track, like it was offset with 30 degrees or so.

The current track on the picture is what it flew as the outbound leg instead of the magenta line as in the FMC.

 

It did a perfect direct entry into the holding, and then continued passed the outbound course and flew this "new" not right holding!

This sentence probably encapsulates a lot of misunderstanding about holding patterns and how they are executed in real life.

 

Michael you're taking it out of context. I know that Anders knows how to fly a real holding. But Anders said that the NGX entered the holding correctly and started another holding 30 degrees off of the original inbound course, and not even following the magenta line inbound. The whole point here is that it didn't follow the inbound leg. In the picture that Anders attached you can clearly see that it's doing its own thing. Given the crosswind it's not supposed to be where it is.

I am not passing any judgment on anyone's ability to fly holding patterns but I obviously could be suspicious unless the person is a certified IFR pilot. There is some degree of misunderstanding about holding patterns that permeates this thread, also there are a few real pilots in this thread - they complain the least or not at all. As I said above - there is a simple test that he could do to check whether something is seriously flawed - fly the same hold with no wind and check results. Plus, his single image is really inconclusive to prove anything, he would have to show the whole sequence of shots and with resolution that makes images a lot clearer.

Here is my attempt, The a/c wants to go wings level on the base leg,and then overshoots the final to the hold,after a correct direct entry.
