Rob Double, from Pyroban, describes the overspeed
Within two minutes, the autopilot disconnected, and five seconds later, pilots began receiving spurious cockpit alarms and alerts about stalling and overspeed
warnings, along with fluctuating airspeed and altitude readings.
light does not momentarily blink when the battery switch is turned on.
Plungers of both materials were tested to determine the effects of side loading forces, overspeed
and overpressure conditions, and low lubricity.
Other features include automatic rotor recognition, overspeed
protection and rotor imbalance detection.
Heading mode gives basic compass directions and overspeed
mode offers additional warnings when approaching speed detection devices.
This is tricky since the U-2 is dynamically unstable, and the difference between stall and overspeed
(and aircraft break-up) is only 15 knots at altitude.
You'll also find light sensitive headlamps, rain sensitive windscreen wipers and an overspeed
warning to avoid any nasty confrontations with the boys and girls in blue.
In wrap configured, traction-driven slitters, attempting to overspeed
the lower slitter system to compensate for upper blade speed loss is impractical.
A combination of a fully adjustable steering wheel, height adjustable front seats, remote control switches for the stereo system, a sensor that switches on the hazard warning lamps under emergency braking and an overspeed
warning system make this a class leader in no uncertain fashion.
The accident may have been prevented if maintenance had not been recently scaled back, and the overspeed
trip had been periodically tested for proper operation.
For example, a coach may train athletes with speed chutes (resisted training), but fail to employ a complementary overspeed
training method such as downhill running.
