Position and Warning

Position and Warning sys

QuestionAnswer
which of the following conditions is most likely to cause the landing gear warning signal to sound? landing gear not locked down and throttle retarded
an airspeed indicator measures the differential betwwen pitot and static air pressure
what landing gear warning device(s)is/are incorporated on retractable landing gear aircraft? a horn or other aural device and a red warning light
in most modern hydraulically actuated landing gear door operation is controlled by sequence valve (landing gear thin ksequence: doors>landing gear>doors again)
(Refer to figure 19) which repair should be made if the gear switch was placed in UP position and the gear does not retract? replace electrical wire #12
what safety device is actuated by the compression and extension of a landing gear strut? ground safety switch
The angle of attack detector operates from differential pressure when the airstream is not parallel to the true angle of attack of the aircraft
which repair would require a landing gear retraction test? gear downlock microswitch
antiskid breaking systems are generally armed by a switch in the cockpit
a typical takeoff warning indication system, in addition to throttle setting, monitors the position of which of the following? elevators, speed break, flaps, and stabalizer trim
(Refer to figure 20) what is the minimum circumstance that will cause the landing gear warning horn to indicate an unsafe condition. any gear not down and locked, and throttle retarded.
at what point in the landing gear operation does normal skid control perform its function? when the wheel rotation deceleration indicates an impending skid
the basic difference between an autosyn and the magnesym indication system is the rotor
the rotor in a magnesym remote indicating system uses a permanent magnet
in a brake antiskid system, when an approaching skid is sensed, an electrical signal is sent to the skid control valve which relieves the hydraulic pressure on the brake
which of the following are some uses for DC selsyn system? indicate the position of retractable landing gear, cowl flaps position, cooler door position, fuel quantity, and position of wing flaps.
the pneumatic (reed) type stall warning system installed in some light aircraft is activated by negative air pressure
in the air with the antiskid armed, current cannot flow to the antiskid control box because the landing gear squat switch is open
Landing gear warning systms usually provide which of the following indications? Red light for unsafe gear, green light for gear down, no light for gear up.
an antiskid system is designed to sense the deceleration rate of every main landing gear wheel and release then reapply pressure at a slightly lower value when a skid is detected.
Microswitches are used primarly as limit switches to control electrical units automatically
when an airplane's primary flight control surfaces are set for a particular phase of flight, such as landing or takeoff, the corresponding control-surface indicating system will show trim position (look up bc im confused)
in an antiskid system, wheel skid is detected by an electrical sensor
the rotor in an autosyn remote indicating system uses an electromagnet
an antiskid system is an electrohydraulic system
(Refer to figure 19) what is the indication of the red landing gear position light under the following conditions? aircraft on jacks; landing gear in transit, warning horn sounding. extinguished
(Refer to figure 20) what will illuminate the amber indicator light? closing the nose, left and right wheel gear full retract switches.
(1.) when an airplane is slowed before approximately 20mph, the antiskid system automatically deactivates to give the pilot full control of the breaks for maneuvering and parking. (2) an antiskid system consist basically of three components; wheel speed both 1 and 2 are true
when landing gear safety switch on a main landing gear strut closes at liftoff, which system is deactivated? antiskid systems
(1) a DC selsyn system is a widely used electrical method of indicating a remote mechanical movement or position. (2) a synchro-type indicating system is an electrical system used for transmitting info both 1 and 2 are true
stall warning systems are generally designed to begin warning the pilot when a stall is imminent
where is the landing gear safety switch usually located? on the main gear shock strut
which of the following functions does a skif control system perform? normal skid control, fail safe protection, locked wheel skid control, touchdown protection
(1) an antiskid system is designed to apply enough force to operate just below the skid point. (2) a warning lamp lights in the cockpit when the antiskid system is turned off or if there is a system failure. both 1 and 2 are true
the primary purpose of a takeoff warning system is to alert the crew that a monitored flight control is not properly set prior to takeoff. the system is activated by a thrust lever
