In the course of studying for the IFR written exam I came on this in the COM section of the AIM publication
3.16.8 Avionics Databases
GNSS avionics used for IFR flight require an electronic database that can be updated, normally on 28- or 56-day cycles. The updating service is usually purchased under subscription from avionics manufacturers or database suppliers.
Database errors do occur, and should be reported to the avionics database supplier. Jeppesen accepts e-mailed database reports at <[email protected]>. It is good practice to verify that retrieved data is correct, and it is mandatory to do so for approach data. Verification can be accomplished either by checking waypoint co-ordinates or by checking bearings and distances between waypoints against charts.
By using the word mandatory does that mean that we have to continue to carry all the paper approaches? or can we cross check with the data from, for example, the ForeFlight, charts.
What is practical, or what is actually done in practice?
Thanks in advance.
