Wind Information
- Control Tower will provide two minutes mean wind values at Rosário and touchdown zone simultaneously with landing clearance or missed approach / go around instructions when landing clearance cannot be issued due to winds exceeding airport published landing limits.
- Further wind information after a landing clearance has been issued will be provided at Pilot’s request or upon occurrence of variations from the last 2 minutes mean wind direction of 60º or more, or mean wind speed of 3 knots or more.
- Instantaneous wind read outs will be provided at pilot’s request.
Wind Limitations
- When landing
1. Maximum of two minutes mean Wind Speed Values indicated by the Touchdown anemometer:
- In the sector 300° to 010° MAG (clockwise) – 15KT, with the maximum Wind Gust of 25KT
- In the sector 020° to 040° MAG (clockwise) – 20KT, with the maximum Wind Gust of 30KT
- In the sector 120° to 190° MAG (clockwise), and if Runway in use is 05 – 20KT with a maximum Wind Gust of 30KT, and if Runway in use is 23 – 15KT, subject also to maximum Wind Gust of 25KT as indicated by MID Anemometer.
2. Maximum of two minutes mean Wind Speed Values,including Gust indicated by the MID or ROSÁRIO Anemometers
- In the Sector 200° to 230° MAG (clockwise) – 25KT.
b. When Taking-off
- 1. Maximum of two minutes mean Wind Speed Values indicated by the MID anemometer:
- In the sector 300° to 010° MAG (clockwise) – 20KT with no Gust limitations
- In the sector 020° to 040° MAG (clockwise) – 25KT with no Gust limitations
- In the sector 120° to 190° MAG (clockwise) and if Runway in use is 05 – 25KT with no Gust limitations, and if Runway in use is 23 – 20KT, also with no Gust limitations
NOTE: The limitations above do not supersede any Operators or Aircraft Operations Manual (AOM) limitations if these are more restrictive
Turbulence
- Attention should be paid to the WIND DIRECTION INDICATORS located on the south side of the runway, near each touchdown area. They will reflect unexpected wind changes. Occasionally they will indicate wind from opposite directions;
- When landing on RWY 05 wind differences greater than 5 KT, between Rosário and MID anemometers, may indicate turbulence on final;
- When landing on RWY 23 with winds from South and Westerly Sectors, one may experience severe turbulence at low altitude over the RWY Threshold;
- Headwind or nearly so, up to 15 KT will cause “WEAK” turbulence on final;
- Wind of 15 KT from sector 020° to 050° MAG (clockwise) may cause “MODERATE” turbulence;
- Wind of 15 KT or even less from sector 300° to 020° MAG (clockwise) may cause “SEVERE” turbulence;
- Down drafts or up drafts are to be expected near the threshold of runways 05 and 23.
NOTE: Pilots are strongly requested to report to the Control Tower as soon as possible any turbulence and/or windshear that may affect operational conditions.
