SearchBirdseyeInFlight Returning Incorrect Results


#1

Hi Flight Aware Team

I’m having a lot of trouble getting reliable results while trying to list cancelled flights for a specific time range.

The following:


https://flightxml.flightaware.com/json/FlightXML2/SearchBirdseyeInFlight?offset=0&howMany=15&query={true cancelled} {> ogtd 1457456400} {< ogtd 1457478000} {ident_or_reg {EZY*} }

Should be returning all cancelled EasyJet flights which were originally scheduled to depart between
Tue, 08 Mar 2016 17:00:00 GMT
Tue, 08 Mar 2016 23:00:00 GMT

It seems simple enough, but not a single of the 15 flights returned was cancelled according to the EasyJet site.

This is just 1 of many examples I have found; In all cases I’ve been lucky to get a single cancelled flight in the results. Am I doing something wrong?

In other queries I also seem to be getting results which don’t even fall between the time range in UTC - is it correct that the ogtd query will be against all flight times in UTC?

Thanks in advance

Phil

#2

The issue I am seeing is that FlightAware gets most tracking data for EasyJet with EZS, rather than EZY.
There is an open case to eliminate this confusion.


#3

Is there anything I can do to remedy the situation on my end (you say there is confusion), or is it a case of bad data on your end?


#4

I would say look for EZS for now.


#5

OK, thanks.

Are there any other similar exceptions that might catch me out? Is the open case for the EZY/EZS issue publicly visible? Is there a way for me to find out once the issue is resolved so I can adjust my system accordingly?


#6

It’s a case for internal use, not public. I will definitely keep you posted with regards to changes as they happen.
And I do not know of similar exceptions. So thanks for bringing this issue up.


#7

Additionally, is it a good idea to add extra query filters for fields that we would not expect to be set for a cancelled flight, such as the following, to try to filter out cases where the cancelled flag is incorrectly set to true?

{= departureTime 0}
{= arrivalTime 0}
{false arrived}
{null waypoints}
{= gs 0}

Can you think of any negative implications to doing this?

If not, are there any other field values you would advise to filter by?


#8

You could use the additional filters, they make sense, but I think a true cancelled should be enough … otherwise we would like to know about it as there may be a bug to be fixed.
In the case of EZY, they all look like legitimate cancellations and would respect all your filters, yet still wrong…


#9

Actually, the ground speed filter would have filtered those results out, unless I’ve missed something?

You missed the following questions from my previous posts:

  • Are there any other similar exceptions that might catch me out? Any other airlines that have data tracked with the wrong icao for example?
  • Is it correct that the ogtd query will be against all flight times in UTC?

Otherwise, thanks for the help. I’ll be sure to let you know about any other problems I spot


#10

Oh yes, I see {=gs 0} definitely gets rid of all those wrongly cancelled EZY.
I said I do not know of similar exceptions.
ogtd is an epoch timestamp so it better be UTC. If you think you found examples that do not respect the interval, post them and we’ll look at it.


#11

My mistake, so you did

I assume the data is stored in the same format then. Great.

I can’t remember exactly, but it could have been a case of the data from other sources saying the flights shouldn’t have appeared within those ranges. I’ll note it down if it crops up again anyway, I couldn’t guarantee that one wasn’t my mistake while trying a bunch of different things.

Thanks again


#12

Hi,
It looks like you wanted to see cancelled flights for several carriers, so I think it’s important to point out that
SearchBirdseyeInFlight with {true cancelled} will return all flights that FlightAware sees as cancelled + those that were cancelled by FlightAware for different reasons.
A lot of those EZY* flights are cancelled by FlightAware, that is why they show up as results to your query. The problem with some of the EasyJet Switzerland flights is that some of the data we receive calls the flights EZY* and some EZS* and this problem will not be fixed soon.

Even if it does, you might still see flights for other airlines that return as canceled when they were not. I expect this to happen rarely, but EZY is definitely heavily affected.
If you know the flights numbers that should be ESZ, then you could ignore the same flight numbers that show up as cancelled EZY.
It could be that your additional filters might get rid of many if not all the flights that are wrongly cancelled:
{= departureTime 0}
{= arrivalTime 0}
{false arrived}
{null waypoints}
{= gs 0}

The next version of FlightXML should stop sending all the flights that were canceled by FlightAware. Until then, which is half year or so away, I am running out of suggestions.


#13

Thanks for getting back.

For anyone else who reads, {= departureTime 0} should actually be {= actualDepartureTime 0}

I’m seeing something a little interesting


https://flightxml.flightaware.com/json/FlightXML2/SearchBirdseyeInFlight?offset=0&howMany=15&query={true cancelled} {airline 1} {= actualDepartureTime 0} {= arrivalTime 0} {false arrived} {null waypoints} {= gs 0}

returns


{"error":"no results"}

Removing the {= gs 0} returns results, but includes results where the groundspeed is actually 0. Should this evaluation be made differently?


https://flightxml.flightaware.com/json/FlightXML2/SearchBirdseyeInFlight?offset=0&howMany=15&query={true cancelled} {airline 1} {= actualDepartureTime 0} {= arrivalTime 0} {false arrived} {null waypoints}

returns

#14

SearchBirdseyeInFlight enforces groundspeed to be an integer.
{= gs 0} should work,. In your case it filtered everything out.
When you removed it, there were some results with unknown empty groundpeed, gs = “”. But since it was decided that groundspeed should be integer, “” was replaced with 0 before showing you the results.


#15

What was the conclusion there?

Is there a way to search where the groundspeed is empty? I notice the less than operator doesn’t seem to be affecting the results correctly when applied to the groundspeed field:


https://flightxml.flightaware.com/json/FlightXML2/SearchBirdseyeInFlight?offset=45&howMany=15&query={true cancelled} {airline 1} {= actualDepartureTime 0} {= arrivalTime 0} {false arrived} {null waypoints} {< gs 1}

One flight has a groundspeed of 294:

Another slight oddness I’ve spotted


https://flightxml.flightaware.com/json/FlightXML2/SearchBirdseyeInFlight?offset=30&howMany=15&query={orig_or_dest {EGKK}} {true arrived} {airline 1} {range arrivalTime 1458288000 1458295200} {> ogtd 1458259200} {< ogtd 1458345599}

The API is saying flight BAW2158 departed at 1458262320 (Fri, 18 Mar 2016 00:52:00 GMT) but according to the BA site the flight is scheduled for 18:45 17th March, and actually departed early

(Today’s flight isn’t scheduled till later today)

And your tracker page agrees with the BA site: flightaware.com/live/flight/BAW2158

#17

That BAW2158 flight seems to match all your filters, I don’t see the problem.
This is the flight returned:

https://flightaware.com/live/flight/BAW2158/history/20160318/0045Z/TLPL/EGKK

The website agrees with the FlightXML result:

departureTime":1458262320 = Mar 17 2016 20:52:00 (America/Anguilla) AST = 18 Mar 2016 00:52:00 GMT

Related to my previous post, the conclusion was that the results were not wrong, but there was a catch. I think you can filter empty groundspeed with {!= gs “”}


#18

My mistake, I conveniently ignored the fact the sites display local time!

Is it safe to assume the groundspeed will specifically be empty in the background, rather than 0, if the flight was cancelled? (to avoid having to query twice, once for empty and once for 0)


#19

{= gs “”} doesn’t seem to be filtering flights out with groundspeed > 0.

And as I mentioned before, the < operator doesn’t seem to do anything against the gs field either

#20

According to docs {null gs} might work.
However, if you are trying to eliminate all wrong cancellations, I am afraid a groundspeed filter is not enough, and no filters will be enough. This call will always return flights cancelled by FlightAware which you probably don’t want to see and there isn’t any combination of filters you can use to filter these out. In other words, SearchBirdseyeInFlight is not the function you should use to see airline cancelled flights.
