Skyvector is horribly “out of date”
Example DCA LDAY RWY19
Jeppesen Depict the updated chart, with NO GS .
Sykvector is say Current “07 OCT 2021 - 04 NOV 2021”
but BOTH charts are dated Amended 1A 29 Mar 2018 ???
The GS on the LDA Y has been decommissioned for many YEARS NOW.
If you were using the SkyVector Plate, you would be wondering why you were not getting any GS information
