new A319s
There appear to be a few glitches with the brand new A319s
1. After 2nd engine start, both N1s spool up uncommanded about 10% for a few seconds before returning to idle?!?
2. The idle is higher than the older models such that on a hot day, you run the risk of cooking the brakes and hence delaying take-off. Either that or you may have to use the brake fans whilst taxiing.
3. After using the speed brakes whilst slowing down on approach and continuing to use them during flap selections, the a/thrust commands a speed down the approach of Vapp +10 kts. I know that Airbus know about this one and require data files to be sent to them for analysis whenever possible.
In short, nothing really to worry about but still curious as this behaviour goes undocumented
