A320 OEI Raw Data ILS Alternate Law Hand Flying issues
 

Hello folks

As part of my initial A320 SIC type rating training, i practiced an ILS ( Raw Data) approach in altérnate law with one engine inoperative.

In past ocassions i had no Issue with handflying an ILS (raw data) with one engine inoperative in normal law, but with altérnate law i am struggling a lot.

i feel that the aicraft do not respond to my sidestick inputs which leads me to an overcontrol situation, where the aircraft bumbles up and down, left and right in order to not miss the LOC and G/S.

i will kindly appreciate if you can give me please some tips or advice to improve my handflying skills during a raw data ils approach in alternate law with one engine inoperative.

Remember that in Alternate Law, pitch control on an ILS is pretty much like Normal Law. Roll control is Direct Law. Pitch control degrades to Direct Law when the gear is selected down. So, once the gear is down, both pitch and roll are in Direct Law.

So, before gear down, you will have auto-trim in pitch You can set the attitude where you want it and then try not to make any pitch inputs. In roll, there is no bank angle hold, so try not to over-control and when you release the roll input, make sure the wings are level.

Once the gear is down, a similar technique applies to pitch control. Try not to over-control and use the trim wheel as required.

Try to sort out one axis at a time. Keep heading corrections small and maybe try 5 degree increments, using 10 degrees of bank.

Similarly, keep pitch corrections small, using 1 degree increments at a time.

It’s not easy and requires practice. Good luck!
