Heathrow (EGLL) SMR Changes Based on New Source Images

[luke11brown]

What are the suggested changes?

I didn't really look at what differences there are, but new source images to be added anyway for SMR/ATM

Sources (if applicable)

Files to be changed (if known)

EGLL/SMR

(be aware that if an enhancement relates more to personal preference - such as colours - the issue may bear discussion)

Assigned to you.

What needs to be done first, is analyse the images vs. our current SMR/ATM. Then list them here, so we can discuss what we need/can change.

For example, the stands are not on the real SMR, but a decision was taken to leave them in by default, due to ease of use.

SMR Differences

(current SMR is on the left, new source images are on the right)

1. The right hand turn from F to B isn't included on source images

2. The outline of terminals 1 and 3 are drawn on the source image, in the middle of all the stands

3. Fire station and a couple of other buildings in that area are drawn on the source images

4. More buildings missing for terminal 2B, 5A, B and C

5. The Cargo apron is drawn very differently on the source images, however as the source images SMR date is 20th of July 2023, there might have been changes to the cargo apron in previous AIRACS, what's currently on the SMR matches the charts.

6. There are some more buildings missing on the eastern side of the airport and border that is currently on the SMR isn't there on the source images

7. Taxiway lines for part of M and AY are not drawn on source images

8. Runway threshold markings appear at the ends of all runways on the source images

9. There are what looks like holding points drawn to the north and south of the grey central parts, in between taxiways A and B, however these aren't included on up to date charts so I think our current SMR is correct. Looking at some more of the SMR these lines appear in lots of places where there aren't holds charted, any ideas on what they are?

10. The control tower is drawn on the source images

ATM Differences

(current SMR is on the left, new source images are on the right)

1. Certain helicopter reporting points are included on the source images however none are included on the current ATM
2. Parts of helicopter routes H10, H5, H9 and H4 are not included on the source images, however the current ATM matches up to date charts

3. This is included on the source images to the east of the airfield, not quite sure what it is, it doesn't appear on the current ATM

4. These are also included on the source images while not on our ATM. Again I'm not sure they are.

As an S1 I have no experience using a ATM, so I'm not sure what should and shouldn't be there so I've probably missed some differences.

That is the Northolt (EGWU) centrelines (already included in the sector file). The large square between them is Northolt itself.

Ah okay makes sense, thanks

@CLC0609 These are the borders of maintenance blocks, which also correspond to the intermediate stopbars; they're charted and published on the Heathrow Airside webpage. Do note that there may well be discrepancies between the SMR and the chart, in which case I'd follow the reference images.

@luke11brown which of these changes would you like me to make?

[matthew4301]

I've found some more differences to the SMR although these might be more relevant to vSMR. Can make a separate issue in the vSMR repo if needed.

LOT282 has a white background behind its callsign, perhaps this means its being towed?

Some of the arrival tags have a H next to the stand number, not sure what this could mean

The arrival countdown also includes aircraft type and stand number
