@paco: Since you have before heard about some questions did you maybe hear if EASA did something with this one:
Consider maximum range speed and speed for maximum angle of climb. How will headwind affect those speeds (everything else remain the same).
What seems the right answer is: Maximum range speed increases and speed for maximum angle of climb remains the same
BUT the correct answer according to comments and an another question bank is: Both speeds remain the same......
Have EASA corrected the question or we shall answer both speeds remain the same to skip contesting the question etc. itd. ? Seriously this is totally strange that other exams got their questions in shape while in this one no one knows what the CAA expect and whether or not they care about what is correct by the book.
