Yaw damper
Cards in this deck (21)
- 1what is the purpose of the yaw dampercounteracts unwanted yaw moments before dutch roll can occur
- 2what can the yaw damper act as, in relation to the autopilotthe 3rd axis of a duplex autopilot
- 3what can an unstable dutch roll lead tofin stall and loss of control
- 4what are the inputs for the yaw damperIRS and air data computer
- 5how does the yaw damper system worksmall deviations in yaw are detected and rudder inputs are automatically applied to prevent dutch roll from occuring
- 6what is the purpose of the ADCit provides speed info to the yaw damper computer so that the correct rudder inputs can be calculated
- 7what rudder input is needed at high speedless rudder input
- 8what aircraft require a yaw damper system, and how manyhave a main yaw damper system and a standby system for redundancy
- 9what is the purpose of calculating the rudder inputsto avoid over or under correcting
- 10what ac are parallel yaw dampers used onolder A/C
- 11how does the parallel yaw damper system workuses same control runs that the pilot uses to apply rudder, the Y/D moves the controls
- 12what is the main advantage of the parallel yaw damper systemyou know when the system is working as you can feel the rudder pedals moving
- 13main disadvantage of the parallel yaw damperssystem "fights" to some extent against pilot input
- 14can the parallel yaw damper system be over riddenthe pedals will react to whichever input the pilot puts in, but if the pilot lets go then it will continue with the yaw dampering inputs
- 15what is a series yaw damperthe yaw damper channel is separate from the rudder channel, meaning that the yd will move the rudder but not the pedals
- 16what is the series yaw damper system much better at dealing withEngine Failure After Take Off
or engine out landing - 17how does the combined system workfitted with both parallel and series Y/Ds but either system may operate depending on the phase of flight
- 18which system will be used in cruisesmall inputs so series
- 19during landing which system is requiredparallel system
- 20how is the yaw damper controlledwith an ON/OFF SWITCH
- 21how can the pilot know what input has been put in from the Y/Dthe indicator swings L and R to show rudder inputs made by the system
providing turn co-ordination
