Maybe somebody has an answer to this? today i was making pictures at 36R, when suddenly this visitor for Schiphol East came in. While i was shooting i heard this plane making a very strange noise. When i was checking my pictures i suddenly saw that this plane has it´s RAM air turbine deployed. Might this be a check or test if it still works properly, or do they only deploy this when there is a serious issue? As far as my knowledge goes, this will only be deployed with engine fall out, or hydraulic preasure loss, but i might be totally wrong of course.....check the nose on the left side. you can clearly see the turbine. If any one has an answer, please let me know........since i have not seen any fire trucks along the runway, i guess this would have been a test run....
