Detailed explanation-1: -Which atmospheric conditions will cause the true landing speed of an aircraft to be the greatest? High temperature with high humidity.
Detailed explanation-2: -as air density decreases (higher density altitude), aircraft performance decreases. A decrease in air density means a high density altitude; an increase in air density means a lower density altitude.
Detailed explanation-3: -RELATIVE HUMIDITY: Relative humidity (RH) (expressed as a percent) also measures water vapor, but RELATIVE to the temperature of the air. In other words, it is a measure of the actual amount of water vapor in the air compared to the total amount of vapor that can exist in the air at its current temperature.
Detailed explanation-4: -rate of flow will be greatest where the pressure is greatest (between metered and unmetered) C. where unmetered is 17 PSI and metered is 5 PSI. Volume and pressure are inversely proportional.
Detailed explanation-5: -Which statement concerning heat and/or temperature is true? There is an inverse relationship between temperature and heat. Temperature is a measure of the kinetic energy of the molecules of any substance.
