Perhaps you have a little extra time indoors with all that is going on in the world these days...
A lot of good material has been put up from the American Bonanza Society on the FAA Wings site. Topics such as: Avoiding Gear Up Landings, BasicMed, Emergency Procedures and Basic Airmanship courses. Each course grants FAA Wings credits and many apply to both Basic and Advanced Wings credit.
Remember, completing 3 of these FREE on line courses counts as the ground school requirement for your BFR. In addition, many of the aircraft insurers will discount your renewals by 10% if you are actively participating.
