From the
options given main wheel spin up is the only reasonable answer. Auto deployment
of the spoilers is achieved first by selecting armed, then a function of air
ground logic sensors, wheel speed, position of landing gear tilt sensors and
throttle position is required to activate the spoilers.
The JAA questions are not type specific and there are normally a number of
interlocks that must be operated before the spoilers deploy. For example on the
A300 rear main wheel speed must be above 70kts.
