Howdy folks! Zooroo here, and today I’d like to remind everyone, especially those who fly at the wrong flight level (FL) that here in IF we are compliant to the real life ICAO flight level standards. The ICAO FL rules are very simple to understand and should be very easily memorized by every pilot in IF. Unless you’re flying in the Chinese, North Korean, or Russian airspace, you need to use standard ICAO aeronautical units (i.e. ft for alt, nm for dis) as these three countries enforce the usage of the metric units (meters and kilometers).
For your reference here is the standard ICAO Flight Level chart for both IFR and VFR. Thanks for your attention.
