 Haparanda atmospheric pressure of 1057 hPa is the highest since 1972.
A military air exercise in Norrbotten had to be canceled. The atmospheric pressure was too high for the instruments of Jas. Yesterday, Monday, January 30 was the air pressure in Norrbotten in 1057 hectopascals, hPa. The highest in 40 years.
Because of it had a large scheduled air exercise set. The reason was
that several instruments in Jas Gripen showed error messages.
This includes altimeter and speedometer, says Mats Hakkarainen, who is flygchef at F 21 in Lulea, the Norrbottenkuriren. Since we are always running to safety, we have suspended all flights until further notice. A plan that Jas Gripen has several different instruments using different techniques and physical phenomena to measure such as altitude and speed. But the classical altimeter uses the ambient air pressure to measure altitude. Then it must be calibrated by the air pressure on the land that becomes the reference for the altimeter. Therefore "hit" even sport aviators in the north of the massive high pressure. From Arvidsjaur announced that the altimeters in flight school plan could only be calibrated against a maximum ground pressure of 1050 hPa. and in Arvidsjaur pressure was 1051 hPa. According to SMHI is high pressure remains over Norrbotten. The forecast for today, Tuesday, January 31 Haparanda have a pressure of up to 1055 hPa. |
