I was in an aircraft yesterday waiting for its turn in the departure queue on the taxiway and noticed that the windsock was showing a direction approximately 30 degrees but directed along the direction we were entering the runway in. i.e. The parallel component would point in the take-off direction & not against it.
Made me wonder: Are there instances when lined up aircraft have to be made to taxi to the other end of a runway due to a last minute wind direction reversal?
Never happened to me, nor seen it mentioned in any ATC conversations / videos online so made me wonder.
Of course, if the parallel component is smaller than the allowable tailwind for the aircraft then I guess it does not matter?
