Ezy6114 Nce To Brs 3/4/08
Hi- Had a GA on the final approach-my first!
Captain said it was due to an unexpected tail wind? Can anyone explain a bit more.Thought these sophisticated airbuses had all the tech to predict weather and speed of aircraft? Anything to do with the short runway at BRS? |
Most companies have very strict limits on the strength of tailwind with which a crew is allowed to land, depending on a/c type. Can't say what the limit is for the EZY 319, but in my company it is only 10 kts, which is little more than a moderate breeze.
Depending on a/c weight and runway length, any tailwind can mean that an a/c will be unable to meet the calculated landing performance criteria for a particular runway, although I would be surprised if that was the case here. As for the a/c systems, yes they are fairly sophisticated and provide accurate data to the pilots on wind speed and direction, but have no predictive ability that I am aware of. Pilots still rely on met forecasts for planning, and actual data from both a/c systems and ATC to monitor the situation on an approach to land. Whilst every effort is usually made to land with a headwind, occassionally situations arise where accepting a slight tailwind is required, often when the wind is a variable crosswind. Unfortunately, if the wind changes significantly during the approach, then a crew can suddenly find themselves with a situation outside of allowable limits, and have no alternative but to make a missed approach. |
