Building Induced Windshear

Alphaprot,

Good summation..however...

I would add Density Altitude (DA) and Building Induced Windshear/Turbulence to the mix....

Note the proximity of the Emirates maintenance hangars (A380 capable) to the Runway...less than 450m!....

Further, note that in general, Automated Weather Stations (AWS) globally, round 'wind direction' to the nearest deca degree (nearest +/- 10 deg)...

Speed is also recorded +/- a margin.....

The density altitude (DA), given the adverse combination of OAT and air pressure at the time was SIGNIFICANTLY HIGHER than ISA for Dubai....

Unfortunately, this crew were subjected to a multitude of adverse environmental conditions (vertical windshear, possible building induced Windshear/Turbulence and an elevated DA) which SHOULD be highlighted by the accident investigation team, if they are on the ball....
