Pressure & Density Altitude Calculations

The pressure on a given day is 1000 hPa at Mount Hotham Airport. What is the pressure altitude on this given day considering the airport elevation is 4500ft above sea level?

Runway 15/33; its length at Amberly Airport is?

The pressure at Murray Bridge Airport is 1018 hPa and the temperature is 25 degrees, calculate the density height given that the temperature should be close to 15 degrees on a given day (elevation 180ft AMSL). For each degree difference multiply it by 120ft. You decide whether to add it or subtract it from the pressure altitude calculation.. Work in teams to solve.

Note: temperature is said to decrease by 2 degrees every /1000ft as you climb from sea level up to a higher altitude. What should be the temperature according to ISA at Murray Bridge?

The temperature at Mount Hotham Airport is 0 degrees and the pressure is 1003 hPa. Calculate the density height on this given day?
