**Exam Questions (HELP)**

Hi All

I'm struggling to work these questions out.

1)*The altitude of an airfield with an ATZ is given as 350ft, how high will the ATZ be above the airfield?*

2)*You are flying at 4300ft on a QNH of 1003 under controller airspace which has base of FL45. Are you in controlled airspace?*

3)*You are travelling at 270knts with a tailwind of 30knts, how long will it take you to travel 150nm?*

4)*You weigh 95kg, your friend weighs 85kg. Your aircraft has an empty weight of 265kg, how many litres of fuel can tou carry without exceeding your MOTW of 450kg?*

Can anyone help me out by showing how to work these out?
