What does a pressure reading of 1013.5 hPa get coded as in remarks?

The correct representation of a pressure reading of 1013.5 hPa in remarks uses a specific coding format. In aviation weather reports, pressure readings are typically communicated in relation to standard atmospheric pressure, expressed in hectopascals (hPa).

For remarks, the value is often encoded by removing the decimal point and writing the number as a whole integer. Therefore, a reading of 1013.5 hPa is represented as 10135 in remarks. This coding method simplifies data transmission and allows for quicker information processing and recognition.

Other options do not conform to this established coding format: "PRESFR" refers to a trend in pressure rather than an absolute reading, "PRES 1013.5" includes a decimal that should not appear in the coded representation, and "1000" does not accurately reflect the given pressure. It is essential to recognize the specific conventions in aviation weather coding to ensure clarity and consistency in communication.
