Explain Me In Flight, How Many Attempts Will The Autostart Perform? |
|
Answer» The autostart will make CONTINUOUS START attemps until the ENGINE either starts or the PILOT aborts the start attempt. FCOM 1 70.20.7 The autostart will make continuous start attemps until the engine either starts or the pilot aborts the start attempt. FCOM 1 70.20.7 |

What Is Holding Current? |
|
Answer» When scr is conducting current in forward conduction STATE, scr will return to forward blocking state when the anode current or forward current FALLS below a low level called Holding current Note: Latching current and Holding current are not same. Latching current is associated with the turn on process of the scr WHEREAS holding current is associated with the turn off process. In general holding current will be SLIGHTLY LESSER than the latching current.

What Is Commutation? |
|
Answer» The currents in the coils connected to a brush are EITHER all towards the brush (positive brush) or all directed away from the brush (negative brush). Therefore, current in a coil will REVERSE as the coil passes a brush. The REVERSAL of current in a coil as the coil passes the brush axis is called COMMUTATION. The currents in the coils connected to a brush are either all towards the brush (positive brush) or all directed away from the brush (negative brush). Therefore, current in a coil will reverse as the coil passes a brush. The reversal of current in a coil as the coil passes the brush axis is called commutation. |

Why Do We Use Compensation Windings? |
|
Answer» COMPENSATION WINDINGS are used to neutralize the cross magnetizing EFFECT of armature reaction. Compensation windings are used to neutralize the cross magnetizing effect of armature reaction. |

What Is The Role Of A Commutator? |
|
Answer» The function of commutator is to facilitate the COLLECTION of CURRENT from ARMATURE conductors. It converts the alternating current induce in the armature conductors into UNIDIRECTIONAL current in the external load CIRCUIT.
