eAPIS
eAPIS became mandatory for all private aircraft into or out of the US effective yesterday - I'm sure that we're all compliant but this just as a reminder as the retribution is specific for non-compliance - a $5,000 fine levied on the PIC for first offence, $ 10,000 for subsequent events.
If you're not familiar with the acronym Google & there's plenty of gen out there.
