You don't know what 666 means in reference to IFR?


Yes-- I don't know. Please explain.

One you have your IFR ticket, you must get 6 hours of instrument time and 6
instrument approaches in 6 months to stay IFR current. Otherwise you will
need an Instrument Comp Check. Thus, 666 is an easy way to remember that.

You still need the 6 approaches in 6 months, but the 6 hours was
eliminated several years ago.
