Classical Mechanics Vector Analysis (Airplane in Wind)

Vector analysis problem taken from Classical Mechanics, 5th Edition, by Tom W.B. Kibble and Frank Berkshire. The problem states:

An aircraft is to fly to a destination 800 km due north of its starting point. Its airspeed is 800 km/h. The wind is from the east at a speed of 30 m/s. On what compass heading should the pilot fly? How long will the flight take? If the wind speed increases to 50 m/s, and the wind backs to the north-east, but no allowance is made for this change, how far from its destination will the aircraft be at its expected arrival time?

I was scratching my head 'cause I don't really understad why the pilot should fly on east of north. Then, I looked out for the meaning of "compass heading" and everything was clear (English isn't my mother tongue). So, if there's anyone else who's strugglin' with this, that's what I found : "heading measured clockwise from north as indicated by the compass". I know it could be pretty obvious for the majority, but I think might be this could be of any help.
Btw, great video and thanks for sharing !
