[REPORTED]32 of 33 airports have conflicting runway lengths

[Bailey]

Hello. While in a mission I clicked on the airport and got 'abc' number from the popup. I measured the lengths of the runways in ME and got 'xyz' number. My measuring guideline was the threshold of the painted perpendicular line right before the piano keys on the runway. If there wasn't a perpendicular line, I used the start and end of the piano keys. If there wasn't that I used the beginning of what looked like the "prepared surface". Differences range from about 200ft to 2000ft in length. Hoping this can get sorted for information purposes, whatever the method.

Great work! To add to this, the elevation of the airports is also quite off as I outlined in this topic. I would say that the airport data needs a check-up.

Do you know the difference between TORA, TODA and ASDA? :huh: Those are the ones that should be compared using RL charts to know the actual values.

 

 

Same with elevation, do you know published elevation is at the airport's mean elevation spot, not the highest nor the lowest? And many times the mean elevation means any random place in the apron, not the actual runway.

 

 

 

S!

Annex 14 definition disagrees with you (highest point of the landing area). Interesting that AIP's use a different standard then.

The example I used (Palmyra) is actually set to the lowest point of the entire airfield so that still doesn't make sense as the min, avg, max is 386,398,411 meter

Yep, different aviation administrations may definitely decide otherwise than others with regards to standards. Still my point stands in you can't just take the ruler in ME and say that's accurate at all if you don't know to what standard the charts were made in the first place, and that making the assumption some RL charts were used to check what's being said in OP.

 

S!

Yes, I understand. That is why I stated this in the OP:

My own review of this suggests that the data on the Airfield in the F-10 menu is static, and not linked to the values of the field, to Baileys point, the runway lengths differ significantly, and the elevations are inconsistently measured especially since these excellent fields all tend to vary in height. I think also the GPS position in a lot of cases seems to be mostly based on the location of the Western most Keys rather than the centre of the airfield.

Hi all

 

I have highlighted this post to the team in a report

 

thank you
