Answer :
The correct option among the following statements is the third option which is that the pressure altitude with an indicated altitude of 1,380 feet MSL with an altimeter setting of 28.22 at standard temperature is 3,010 feet MSL. What is meant by pressure altitude?
The pressure altitude is the vertical elevation above the mean sea level. It is determined by adjusting the barometric pressure reading for standard temperature. The altitude at which the atmospheric pressure matches the barometric pressure, known as the standard atmospheric model, is known as the pressure altitude. What is indicated altitude? Indicated altitude is the altitude shown by the altimeter with the barometric scale set to the existing pressure conditions. On the altimeter, it is represented by the black arc. Indicated altitude is affected by both instrument and installation error, and it is affected by changes in barometric pressure. How to calculate pressure altitude?The formula for calculating pressure altitude is: PAlt = 145366.45 * (1 - (29.92 / QNH)^0.190284)Where: PAlt is Pressure Altitude and is in feet29.92 is Standard Sea Level Pressure in inches of mercury QNH is Altimeter Setting or Barometric Pressure at Mean Sea Level and is in inches of mercury145366.45 is a constant determined based on the value of g (gravity acceleration) used in the calculations. The formula can be rearranged as QNH = 29.92 * (1 - ((PAlt / 145366.45) ^ 0.190284))Thus, using the formula, the pressure altitude with an indicated altitude of 1,380 feet MSL with an altimeter setting of 28.22 at standard temperature is: PAlt = 145366.45 * (1 - (28.22 / 29.92)^0.190284)= 3010 feet MSL (approximately)Therefore, the correct option is C. 3,010 feet MSL.
