Georeferenced Approach plate NOT!!


Recommended Posts

Last month I flew to KLXT (Lee's Summit MO) for a dog rescue.  I was surprised to see the plate for their GPS rwy36 marked at the top to indicate NO georeferencing data available.   Some of the other approaches to KLXT are georeferenced.

 

I searched Mooneyspace for info on approaches lacking georeferencing, but came up blank.  My questions:

 

  1. I fly behind FlyQ.  Does the KLXT GPS 36 in Foreflighalso have geo-data?  I think Seattle Avionics data drives both software.
  2. any info on why data would not be available for certain plates?
  3. are there many other approaches without geo-data (this is the first I've encountered)?

Most likely an iFlyQ issue. However, not all approach plates/airport diagrams/arrivals/departures are able to be georeferenced due to note being drawn to scale or some other oddity of the plate's reference data not meshing into the code.

 

Something in iFly's code didn't line up. Give them a shout and let them know. With 15,000+ terminal procedures there are bound to be a couple glitches in the matrix.

I'm going to steal this thread for a moment. I have to renew my Foreflight next month I have basic and am thinking to upgrade to pro. My reciever is the basic Dual do I have to replace it with the more expensive reciever like a stratos to get the advantages of the Foreflight pro?

You actually don't even need the dual if your iPad has the GPS built in. If you like ForeFlight you can eventually buy a Stratusn and enjoy ADS-B in capabilities.

Bodie, how do you like the syn vis . I was going to update a couple days ago and did not due to having to stopping the old subscription and adding the new subs and include the syn vis option.seem silly but I most likely will do it soon.

A reply from Seattle Avionics' Keith Russo:

HI Neil,

Great question! The plate is legal to fly even without the geo-ref. In any case, this one did not pass our technical qc checks. Normally these get resolved within a cycle or two by the FAA.

I have flagged this plate to be reviewed again. Thanks for your feedback!

Fly Safe!

 

...and my reply to Russo:

Thank you for the quick reply.  However, you imply that this is a problem with the FAA.  Why, then, does the same IAP work in Foreflight?  Also, approximately how many IAPs in FlyQ, on the average, will exhibit this problem?  Is it rare and I just was unlucky in December?

and this from Seattle Avionic CEO Steve Podradchik, 

 

This is the difference between certified FAA DO-200A plates (FlyQ) and non-certified data that ForeFlight uses.

I just reviewed the plate. The FAA happened to have updated it for the cycle that starts on Thursday. And that's a good thing because we didn't geo-ref the old version because the FAA didn't do it right and it flunked our validation process. The new plate passed validation so you'll see it calibrated in a few days.

To be clear -- this is NOT a problem but a benefit to getting plates checked multiple times by different people for accuracy before they're released. Apparently ForeFlight has no such checks. Keep in mind we supply geo-ref data to 20+ apps and devices including certified systems like Aspen and Bendix-King so we have to accurate. In fact, in about 9 years of doing this and having processed over 1 million plates, we have precisely 1 case of us making a mistake -- that's a better track record than Jepp.

The FAA makes a few mistakes every month and have some plates, most notably VOR or NDB approaches, that have only one navaid on the plate (and no fixes) so there is no other way to cross-check the plate accuracy so we can't certify them.
