Many different factors affect the density of air. Most measurably, as altitude increases, air becomes less dense, decreasing atmospheric pressure. Standard altitude-pressure tables allow ...

"We are working to determine if this bad data for pressure altitude only affected the [flight data record], or if it was more pervasive throughout the helicopter's other systems. We will have an ...

Normally, investigators would be able to use pressure altitude to compute the barometric altitude displayed to the pilots. Because the pressure altitude parameter is invalid, they have to use ...

The iPad is an engaging visual tool, but many pilots forget about its many audio uses. Especially for those pilots who worry ...

Back home after his trip, he built this simple Temperature, Altitude and Pressure Display Device using a few off the shelf parts. Following a brief search, he zeroed in on the BMP 180 sensor ...

you can probably return to that altitude without problems as long as you are properly acclimatized. The concentration of oxygen at sea level is about 21% and the barometric pressure averages 760 mmHg.
