circling ?

[alpergokgoz]

what is left or right circling:D

[Scuzi]

Orbiting? Holding?



What?:confused:

Do you mean "Visual Manouvering (circling)" - VMC (but not abbreviated to VMC because VMC is already in use.

Visual Manouvering (Circling) is where the aircraft makes an approach to one one runway, then at a point when they are visual with the airfield (and a number of other factors), fly round to the runway in use (due to wind or topography).

This is something that happens at airfields where this is instrument approaches to ONLY one runway; Biggin Hill, Cranfield immediately spring to mind.

That the answer to the question?

[ATCO2]

There are to types of circling.
1. Circling approach to Instrument RWY xx and
2. Circle to land (for other RWY).

what does it mean:

1. Some instrument procedures designed for certain RWY may be offset up to 30 degrees. If they are offset, instrument procedure may be called for example VOR/DME Circling RWY xx. Specification for offset is set by ICAO for cat a,b,c,d approach. In that case you land on that RWY for which Instrument approach is designed and,

2. Circle to land, means that you make instrument approch for RWY xx and due to mainly strong wind, aircraft on the instrument approach procedure, having RWY in sight, may ask for Circling for another RWY. Pilot is performing that manoeuver constantly having RWY in sight and of course it is done visually.

You may take a Jeppesen charts to see some procedures with both options where in case of circling to land there are different minima specified and displayed on the Instrument approch chart.

If I am wrong, please correct me.

Hi ATCO2:
I was wondering if the wind is too strong, is it possible for the aircraft to use another runway, what if it 's down to the wind?

[Permanent Standby]

It normally iis down to the wind or you would land on the instrummeent RWY. e.g. If the wind is 360/20kt but you only hhad an ILS on RWY 18, you would fly the ILS until you were at Cirling Minimma then fly the circling procedure (basically a low visual circuit) to RWY 36. (no aircraft I know have a tailwind limit above 15kts)

Can also be a function of terrain: have a look at the Riviera approach and circle with prescribed tracks for 22 at Nice.
