Nope. 26TX is "Lowrance Ranch".
The sectional on iFly shows it as "TX26" and it's in AirNav as "TX26".
To go to the source: The latest sectional downloaded from the FAA website (https://www.faa.gov/air_traffic/flight_info/aeronav/digital_products/vfr/), for San Antonio (San_Antonio_104_P.pdf), shows it exactly as it's shown on iFly's sectional, as TX26.
Lat/long (according to AirNav): 30.3129000,-97.7594333
If I click on the "H", I get a pop-up box but it's not for a heliport (see attached). If I click "Search Nearby...", then the heliport doesn't show up on the list. The lat/long shown at the top is almost identical to what's provided in AirNav.
Like I said... this particular heliport (to me) is not a big deal. I just wanted to know -- if it happens to me again, with a more important piece of geodata -- the procedure to report an airport (or similar) that should be in the iFly database, but isn't (like this one).
