- Performance and density
- Airplanes' performance determined by air density.
- More Air Density = More Lift & More Power
- The density of air is decreased by following condition
- High Altitude or Low pressure
- High temperature
- High humidity
- Low density = Low performance
- Density altitude
- Aircraft performance in Standard Atmosphere expressed in altitude to have better idea.
- to know aircraft performance
- Standard atmospheric condition.
- At sea level = 15 degrees C, 29.92 in Hg.
- Temperature = -2 degrees C/ 1000 ft (about)
- Pressure = -1 in Hg/1000ft (about)
- Density altitude Increase = Less Air (density)
- Performance decrease.
- Less Lift
- Less Thrust
- Slow climb
- Longer takeoff and landing run
- More accident (High Altitude Airport during Hot Summer)
- pressure altitude corrected for nonstandard temperature. (other way to explain)
- Density Altitude Chart
- to determine density altitude with Pressure Altitude and Temperature
- to predict performance of an aircraft on given day.
Performance Charts and Tables
- Indicated Altitude corrected for nonstandard pressure.
- to determine the density altitude (and other performance of an aircraft)
- Transponder Mode C and Flight Level use pressure altitude
Cross Wind Component Chart
- Take off distance chart
- Landing distance graph
- Landing distance table
- Cruise power setting
- on Landing in Strong Wind
