VFR navigation chart An aeronautical chart (using a scale of 1:500 000) designed for visual navigation of slow- or medium-speed aircraft. Topographic information on these charts features the portrayal of relief and a judicious selection of visual checkpoints for VFR flight. Aeronautical information includes visual and radio aids to navigation, airports, controlled airspace, restricted areas, obstacles, and related data.

VFR OTT Abbreviation for: VFR over-the-top Fr: VFR OTT
VFR over-the-top A VFR flight in which a pilot climbs in visual meteorological conditions (VMC), proceeds en route above inclement weather, and descends in VMC at a destination that had been forecast for conditions surpassing VMC for a period extending before and after the estimated time of arrival (ETA).
. abbreviation: VFR OTT
Note: VFR over-the-top does not exist in the U.S.
Fr: vol VFR au-dessus de la couche
VFR terminal area chart An aeronautical chart (using a scale of 1:250 000) that depicts terminal control area (TCA) airspace, which provides for the control or segregation of all aircraft within the TCA.
