Under what conditions is indicated altitude the same as true altitude?
Under what condition is indicated altitude the same as true altitude? B : Indicated altitude (what you read on your altimeter) approximates the true altitude (distance above mean sea level) when standard conditions exist and your altimeter is properly calibrated.
Which condition would cause the altimeter to indicate a lower altitude than true altitude quizlet?
Under what condition will true altitude be lower than indicated altitude? A : The airplane will be lower than the altimeter indicates when flying in air that is colder than standard temperature. Remember that altimeter readings are adjusted for changes in barometric pressure but not for changes in temperature.
Under which condition will pressure altitude be equal to true?
Under which condition will pressure altitude be equal to true altitude? B : Pressure altitude equals true altitude when standard atmospheric conditions (29.92" Hg and 15 degrees C at sea level) exist.
What is the difference between indicated and true altitude?
Indicated Altitude is the altitude shown on the altimeter. True Altitude is height above mean sea level (MSL). Absolute Altitude is height above ground level (AGL). Pressure Altitude is the indicated altitude when an altimeter is set to 29.92 in Hg (1013 hPa in other parts of the world).
How does temperature affect indicated altitude?
Effect of Cold Temperature on Barometric Altimeters For example, at 5000 feet above sea level, the ambient temperature on a standard day would be 5 degrees Celsius. When the ambient (at altitude) temperature is colder than standard, the aircraft's true altitude is lower than the indicated barometric altitude.
What is the indicated altitude?
Definition of indicated altitude : the height above sea level as read on an altimeter.
How do variations in temperature affect the altimeter?
How does temperature affect altimeter readings? In conditions that are colder than standard temperature, the altimeter will overstate your altitude. The higher your altitude, the more it will be overstated. In conditions that are warmer than standard temperature, the altimeter will understate your altitude.
Which factor would tend to increase the density altitude at a given airport?
Density Altitude increases with an increase in humidity. Density Altitude decreases with a decrease in humidity. Or, remember relative humidity directly affects Density Altitude.
Under what conditions does pressure altitude have the same value as density altitude?
Under what condition is pressure altitude and density altitude the same value? At standard temperature.
Does true altitude change with temperature?
The colder the temperature, the more significant (and possibly dangerous) this difference can be. When the temperature is colder than standard, you are at an altitude lower than your altimeter indicates. When the temperature is warmer than standard, you are higher than your altimeter indicates.
Under what condition is indicated altitude the same as true altitude quizlet?
At standard temperature. Under what condition is indicated altitude the same as true altitude? When at sea level under standard conditions.
Whats the difference between true altitude and density altitude?
Density altitude – The density altitude is defined as the altitude that is pressure corrected or relative to the measurement of temperature. It allows for the measurement of nonstandard temperature variations. True altitude – True altitude determines the actual elevation of the aircraft above mean sea level (MSL).
How does cold weather affect you true altitude compared to your indicated altitude?
Air expands as the temperature increases and it compresses when the temperature decreases. When it is colder than ISA, the air column is compressed and therefore you are flying lower than the altimeter is indicating. In other words: the altimeter will over read in cold air.
Why is indicated altitude lower on warm days?
The correct answer is A. On warm days the air expands and is less dense than on a cold day, and consequently raises the pressure levels. For example, the pressure level for 5,000 feet will be higher than on a day with standard conditions; the altimeter may indicate 5,000 feet when the airplane is actually at 6,000.
How does non standard temperature effect indicated altitude as compared to true altitude?
Effect of Cold Temperature on Barometric Altimeters For example, at 5000 feet above sea level, the ambient temperature on a standard day would be 5 degrees Celsius. When the ambient (at altitude) temperature is colder than standard, the aircraft's true altitude is lower than the indicated barometric altitude.
When density altitude is beyond capability as indicated on the performance chart?
669- When density altitude is beyond capability as indicated on the performance chart, A: do not attempt takeoff until conditions permit calculations that result in data showing a safe takeoff and climb out.
Is density altitude the same as true altitude?
Density altitude – The density altitude is defined as the altitude that is pressure corrected or relative to the measurement of temperature. It allows for the measurement of nonstandard temperature variations. True altitude – True altitude determines the actual elevation of the aircraft above mean sea level (MSL).
Under what conditions are density altitude and pressure altitude the same?
Under what condition is pressure altitude and density altitude the same value? At standard temperature.
When the sea level pressure is higher than the altimeter setting the true altitude will be higher than the indicated altitude?
Many aircraft altimeters cannot be adjusted above 31.00 “Hg. When an aircraft's altimeter cannot be set to a pressure setting above 31.00 “Hg, the aircraft's true altitude will be higher than the indicated altitude on the barometric altimeter.

What effect does high density altitude as compared to low density altitude have on propeller?
What effect does high density altitude, as compared to low density altitude, have on propeller efficiency and why? Efficiency is reduced because the propeller exerts less force at high density altitudes than at low density altitudes.
Which statement is true regarding takeoff performance with high density altitude conditions?
Which statement is true regarding takeoff performance with high density altitude conditions? The acceleration rate is slower because the engine and propeller efficiency is reduced.
Is true altitude the same as density altitude?
Density altitude – The density altitude is defined as the altitude that is pressure corrected or relative to the measurement of temperature. It allows for the measurement of nonstandard temperature variations. True altitude – True altitude determines the actual elevation of the aircraft above mean sea level (MSL).
What are the factors that affects the altitude indication and explain?
The conditions that result in a high density altitude are high elevations, low atmospheric pressures, high temperatures, high humidity, or some combination of these factors. Lower elevations, high atmospheric pressure, low temperatures, and low humidity are more indicative of low density altitude.
What conditions provide low density air?
A number of factors (altitude/pressure, temperature and humidity) influence air density. A higher altitude, low pressure area, higher temperature and high humidity all have one result: they lower the density of the air.
Which statement is true about the effect of temperature changes on the indications of a sensitive altimeter?
Which statement is true about the effect of temperature changes on the indications of a sensitive altimeter? Colder-than-standard temperatures will place the aircraft lower than the altimeter indicates.
Which atmospheric conditions will cause the true landing speed of an aircraft to be the greatest?
Which atmospheric conditions will cause the true landing speed of an aircraft to be the greatest? High temperature with high humidity.
Under which condition will the rate of flow of a liquid through a metering orifice or jet be the greatest?
rate of flow will be greatest where the pressure is greatest (between metered and unmetered) C.
Which atmospheric conditions will cause the true landing speed?
Which atmospheric conditions will cause the true landing speed of an aircraft to be the greatest? High temperature with high humidity.
Which condition is the actual amount of water vapor in a mixture of air and water?
Absolute humidity is the actual amount of the water vapor in a mixture of air and water. It is expressed either in grams per cubic meter or pounds per cubic foot. The amount of water vapor that can be present in the air is dependent upon the temperature and pressure.
