Not so Kestrel,
The spoilers are ( in the armed position) fully extended and the lever driven to the up position, when the main gears are untilted and the thrust levers are at idle. Failing this they are also extended when either reverse thrust lever is moved to the reverse idle detent, provided again the main gear trucks are in an untilt condition. In the latter case the speedbrake lever does not need to be in the armed position.
The nose gear A/G compression sensing logic is used for controlling stall warning and portions of the caution and warning system.
