N/A

Question 12

Periodic engine run-ups are important even though engine anti-ice is on. The purpose is to shed ice before it accumulates to a point where it could do damage to the engine when ice sheds.

Ice may build up on engines while there appears to be no visible accumulation on other aircraft surfaces. This is due to a temp drop as ambient air enters the engine inlet.

Answer 21

N/A

Question 22

Answer 23

Second window forward and six Windows aft emergency exit window.

Question 24

Wing check best vantage point on the A319

Answer 24

Third window forward and sixth window aft the emergency exit window.

Question 25

Once cleared for take off, run-up both engines to 50% N1. If no engine vibration noted, release brakes and continue takeoff. If significant vibration, clear the runway and complete another engine run-up. If vibration continues contact maintenance.

Answer 25

N/A

Question 26
