# circling minimums

## circling minimums

Circling minimum indicated on approach charts.
The minimum descent altitude (MDA) and visibility required for the circling procedure.
circuit
i. The pattern followed by an aircraft from takeoff to landing. It consists of takeoff; climb straight ahead; turn onto the first crosswind (through 90°); turn onto the downwind—where the track the aircraft is following is parallel to the runway but opposite to the takeoff or landing direction; turn onto the base leg (through 90° to 135°); and final approach terminating in landing. On aircraft carriers, the circuit may be circular. Also referred to as an aerodrome traffic circuit.
ii. A path, consisting of various electrical devices joined by wires, to allow an electrical current to flow continuously through it.

Not only are circling minimums NA for Cat C and D, but so are straight-in mins.
There is no free lunch, of course, so remember that the new circling criteria expand the area of protected airspace, generally, by raising circling minimums themselves, to provide more obstacle-free airspace in which to perform the maneuvers.
You can call up an approach chart without fear (or guilt) that maybe the circling minimums changed last month.
The whole thing started when a reader asked about an approach to a Runway 26 that had the note, "Rwy 26 Straight-in and Circling minimums NA at night.
Some will restrict themselves to taking off only when circling minimums for the approach exist at the time of departure.
Good to know, even accepting that's 1200 feet above the runway, or a 24-degree descent angle to land straight in, and it's 600 feet above circling minimums.
In a circle-to-land maneuver, you must maintain circling minimums until you are in a position to make a normal rate of descent to the touchdown point.
Add departure minimums like, "Departure ceilings and visibility must be at or above circling minimums for an available approach.
Many current RNAV approaches list several different sets of minimums, including circling minimums, and an "LNAV MDA," as if you were using GPS in lieu of a localizer on a non-precision approach.
