Aerodrome Reference Temperature Formula:
| From: | To: |
Aerodrome Reference Temperature (ART) is the monthly mean of the daily maximum temperatures for the hottest month of the year. This temperature is averaged over a period of years and is crucial for aviation operations and airport design considerations.
The calculator uses the Aerodrome Reference Temperature formula:
Where:
Explanation: The formula calculates the reference temperature by taking the average daily temperature and adding one-third of the difference between the monthly mean and average daily temperatures.
Details: Accurate ART calculation is essential for airport design, runway length determination, aircraft performance calculations, and ensuring safe aviation operations in various temperature conditions.
Tips: Enter both temperature values in Kelvin. Ensure the values represent the hottest month of the year and are averaged over an appropriate period.
Q1: Why is ART important for aviation?
A: ART helps determine aircraft performance characteristics, runway requirements, and operational limitations under specific temperature conditions.
Q2: What time period should be used for averaging?
A: Typically, temperature data should be averaged over at least 5-10 years to account for climatic variations.
Q3: How does ART affect aircraft operations?
A: Higher ART values can reduce aircraft performance, requiring longer runways and affecting payload capacity.
Q4: Are there international standards for ART calculation?
A: Yes, ICAO and other aviation authorities provide guidelines for ART calculation and its application in airport design.
Q5: Can this calculator be used for non-aviation purposes?
A: While designed for aerodrome reference, the formula can be adapted for other temperature reference calculations.
