How to determine if Brake Pressure is low
White normal, Amber below limit boxed, BRAKE PRES LO(CONFIG) One or both brake accumulator pressures are low.
what does red mean on the gear lights SD colors

which gear used for ground shift
nose gear
explain antiskid system
1 max brake without skidding 2 prevents brake application until wheel spin-up, At low speed automatically disabled to allow manual braking , tested automatically when power applied, when malfunction occurs an anti skid alert is displayed.
How is braking affected with loss of hydraulic pressure.
each main gear wheel disc-type brakes operated by 2 independent hydraulic systems. Both hyd brake systems power each brake assembly, Accumulator sufficient capacity to stop the airplane
how is nose gear steering affected by emergency gear extension
When the lever is raised the right hyd system is isolated front the landing gear. Nose steering to the left is restricted even when both hydraulic systems are operating.
the conditions that allow the aural gear warning horn to be silenced by pushing the gear horn switch
Landing gear warning horn and vocal warning will sound when
1) Landing gear is not down and locked with flaps extended in the landing range(cannot be silenced)
2) Landing gear is not down and locked, throttles retarded, airspeed less than 210KIAS and altitude below 1200 feet (may be silenced)
How are brake temperatures depicted
amber and white on SD Configuration page brake temp differential of up to 60 deg C is normal
what is the gear handle release
Allows pilots to raise the gear handle in the event of ground shift system malfunctions after takeoff.
what is also tested when the annun LT test button is pushed
When the annum is pushed a warning horn and voice warning will sound to alert the crew of a gear unsafe condition.
