I have a subscription at https://www.vafinancials.com/v5/vcas/, a closed-source service. From a web control panel, you can bring up Pilot Reports (PIREPs) like this:
https://www.vafinancials.com/clientweb/flightlog.php?fn=35e097e62bec9147861a575a8f5a1264&va=18517&fy=2019&fm=11&fd=17
But only one at a time.
In that URL, the "fn" is each PIREP's unique address, va
is constant, fy/m/d
refer to the date.
With this information and the appropriate login credentials, can someone advise if it is possible to retrieve 1000s of PIREPs en-masse from the site?
