My philosophy for not fully alligning the ADIRS on every leg and sometimes not even when receiving an aircraft on transit...
Hmmm , you got me in throuble now
Itīs just that after doing full allignments for so many years and doing quick ones now for for 2 years I honestly donīt see any difference in navigation accuracy or other parameters.
Airbus FCOMīs say not even a quick onīs neccesary if less than 5 kts GS remain shown ,
well not for me.
I do at least a quick one with a Gate coord. entry.
The aircraft screws up consistently or makes good consistently at the airports we go irrespective of the kind of allignment we made before departure.
As far as checking the batt. backup well you guys may also have a point there , now , my good F/O will lose it anyway after the 5 min. and I will have the No. one or three option so thats the way I made peace with that .
Our route structure can make us do up to 8 legs a day or it can only be one 4 to 6 hour leg per day.
