Meteo wind

The airspace app uses gps readings to calculate the prevailing wind speed and direction during the flight. To ensure a reliable estimation it’s necessary a minimum number of samples in a wide range of directions of flight. That’s why the calculation may take over 10 minutes.

When the app has finished the calculations it informs the pilot with a speech like:

Wind: 10 kilometers per hour from northwest

The unit of measure for the wind strength is the same used to measure the speed and can be modified in the user preferences screen. The wind direction resolution is 22.5º because there are 16 possible directions: North, North-northeast, Northeast, East-northeast, East, …

If the prevailing wind direction or strength changes in more than 5 kmh during the flight the app will be reported to the pilot with one speech. If there are not significant changes the app will repeat the speech every 10 minutes. This changes in the wind can be due to weather changes or to the fact that the pilot has moved to a different zone. Wind changes are frequent when we ascend or descend in altitude. Airspace app uses an adaptative time window to reach a compromise among reliability and response time.

This wind estimation is the base of another estimations made by the app like the time and altitude needed to reach a waypoint.

Air density

I live close to the sea and when I move to a fly site in the interior of the country at an altitude of 4500 feet above the sea level I can see a lot of pilots taking off with a wind speed of 30 kmh They say 30 kmh at 4500 feet are not the same as 30 kmh at the sea level.

Altimeter calibration

Pressure based altimeters have been relegated in favor of gnss receivers for the estimation of altitude mainly because they need to be calibrated with QNH. QNH can change in more than 5 hPa (50 mts) during the flight or between places more than 50 km apart.

Glide farthest

Las teorías tradicionales para el cálculo de la velocidad de planeo máximo no sirven cuando el curso de vuelo no coincide con el rumbo. Prácticamente ningún instrumento tiene esto en cuenta cuando calcula la velocidad de planeo máximo.

Lag-free variometer

Variometers that rely only in pressure sensor readings suffer from delays of more than 500 msg. The delay of the vario has a direct impact in pilot’s reaction time and in his learning proccess of wing reactions to thermal turbulence.

Meteo wind estimation

One of the main features of today glide computers is the estimation of wind, the speed and direction of the air mass we’re moving in. It’s the base of other glide insturment estimations like the required time and altitude to reach a waypoint.

Unreliability of total energy variometer

The total energy variometer takes into account the dynamic energy exchanges with both horizontal and vertical motions of air. So, their indications are gathered together and delayed misleading the information necessary for the location of thermals.
