# which condition would cause the altimeter to indicate a lower

When the ambient (at altitude) temperature is colder than standard, the aircraft’s true altitude is lower than the indicated barometric altitude.

## What would cause the altimeter to read higher than true altitude?

The altimeter is calibrated to the pressure reported by the ground station. Therefore, it IS accurate on the ground. But colder, denser air, as DeltaLima points out, will have a steeper pressure gradient–so as you climb above ground, the altimeter indicates altitude rising faster than the true height.

## What does low altimeter setting mean?

Low Barometric Pressure: An abnormal low-pressure condition exists when the barometric pressure is less than 28.00 “Hg. Flight operations are not recommended when an aircraft’s altimeter is unable to be set below 28.00 “Hg. In this situation, the aircraft’s true altitude is lower than the indicated altitude.

## Under what condition will true altitude be lower than indicated altitude with an altimeter setting of 29.92 HG?

Under what condition will true altitude be lower than indicated altitude with an altimeter setting of 29.92″Hg? In colder than standard air temperature.

## Which condition would cause the altimeter to indicate a lower altitude than true altitude quizlet?

Which condition would cause the altimeter to indicate a lower altitude than true altitude? In air that is warmer than standard temperature, the airplane will be higher than the altimeter indicates. Said another way, the altimeter will indicate a lower altitude than actually flown.

## What factors cause the indicated altitude to differ from the true altitude?

When the temperature is warmer than standard, you are higher than your altimeter indicates. When you are flying above a location for which you obtained a local current altimeter setting in extremely cold temperatures, the true altitude of the aircraft can be significantly lower than indicated.

## Which condition would cause the altimeter to indicate a lower altitude than a true altitude?

When the ambient (at altitude) temperature is colder than standard, the aircraft’s true altitude is lower than the indicated barometric altitude. When the ambient temperature is warmer than the standard day, the aircraft’s true altitude is higher than the indicated barometric altitude.

## What would cause the altimeter to read higher than true altitude?

The altimeter is calibrated to the pressure reported by the ground station. Therefore, it IS accurate on the ground. But colder, denser air, as DeltaLima points out, will have a steeper pressure gradient–so as you climb above ground, the altimeter indicates altitude rising faster than the true height.

## Under which condition will pressure altitude be equal to true altitude quizlet?

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.

## Which condition would cause the altimeter to indicate a higher altitude than true altitude?

The increase in pressure causes the altimeter to read lower, not higher, than actual altitude. When flying from higher pressure to lower pressure without adjusting your altimeter, the altimeter will indicate a higher than actual altitude.

## What factors cause the indicated altitude to differ from the true altitude?

When the temperature is warmer than standard, you are higher than your altimeter indicates. When you are flying above a location for which you obtained a local current altimeter setting in extremely cold temperatures, the true altitude of the aircraft can be significantly lower than indicated.

## How is an altimeter made to indicate higher altitudes?

A simple barometric altimeter includes a sealed metal chamber, a spring, and a pointer that shows altitude in meters or feet. The chamber expands as air pressure decreases and contracts as it increases, bending the spring and moving the pointer.

## Which condition would cause the altimeter to indicate a lower altitude than true altitude group of answer choices?

Which Condition would cause the altimeter to indicate a lower altitude than true altitude? C) In air that is warmer than standard temperature, the airplane will be higher than the altimeter indicates. Said another way, the altimeter will indicate a lower altitude than actually flown.

## What is a low altimeter setting?

The minimum safe altitude of a route is 19,000 feet MSL and the altimeter setting is reported between 29.92 and 29.43 “Hg, the lowest usable flight level will be 195, which is the flight level equivalent of 19,500 feet MSL (minimum altitude (TBL ENR 1.7-1) plus 500 feet).

## What does altimeter setting tell you?

Altimeter setting is the value of the atmospheric pressure used to adjust the sub-scale of a pressure altimeter so that it indicates the height of an aircraft above a known reference surface.

## What would cause an altimeter to indicate a lower?

When the ambient (at altitude) temperature is colder than standard, the aircraft’s true altitude is lower than the indicated barometric altitude. When the ambient temperature is warmer than the standard day, the aircraft’s true altitude is higher than the indicated barometric altitude.

## Does a higher altimeter setting mean higher pressure?

Since the altimeter setting is more than 29.92 in., the air in this example has a higher pressure, and is more compressed, indicative of the air found at a lower altitude.
