TomKrajci ๐บ๐ฆ ๐ณ๏ธโ๐ ๐ณ๏ธโโง๏ธThe glider instruments need to be tested in a more holistic way...as holistic as you can get when the fuselage is sitting in the garage.
First photo shows tubing attached to the pitot probe. The long external tube allows me to add pressure to the pitot system while looking at the instruments on the panel.
Second photo shows the airspeed indicator (small round display) and glide computer screens. Both of those systems have pitot pressure sensors. I have pressurized the external tubing so that the airspeed indicator shows about 105 knots indicated airspeed. As you can see in the lower part of the glide computer display (V IAS)...the two devices agree within about 1 knot. I can't ask for better than that. (The vario also has a pitot pressure input, but it also uses GPS. It's very confused and angry that GPS says the glider is stationary, but it's supposedly moving through the air at a ridiculous speed. I may have to wait until flight testing to really evaluate the total-system performance of this advanced vario.)
Another bit of good news is that the leakage rate of the pressurized and sealed pitot system is pretty low. After a minute or two the indicated airspeed only drops a few percent at the most. That's not perfect, but it's pretty good.
Third photo shows what the instrument panel looks like when all the devices/screens are running. That's right, if I lose electrical power, my instrument panel is a blank, black hole.
Since I powered up all the screens, it means I'm ready to hook up an ammeter to measure current draw of each device, and my maximum load when everything is running. I'll do that tomorrow.

23XI Racing ๐คWant to come check out our new ๐ก? The Airspeed lobby will be open from 9-4 Monday through Friday now that we have officially welcomed fans into the building with Airspeed Premiere. We are also going to have special hours this Saturday, May 25 and open the lobby from 9-12. #airspeed
With only 3โฃ days until Airspeed Premiere, we figured we would give another sneak peek this time with our state-of-the-art gym. #Airspeed #ForwardTogether

ScienceActuallyDepending on the species, the airspeed velocity of an unladed swallow ranges from 32.3kmh (20,1mph) to 38.8kmh (24mph).

sidenote : the four capitals of Assyria were Ashur (or Qalat Sherqat), Calah (or Nimrud), the short-lived Dur Sharrukin (or Khorsabad), and Nineveh - of which the ruins of all four ancient cities fall within the modern state of Iraq.

BoiglenoightGot a call from โJohnโ speaking on behalf of the local #police soliciting for a donation. The conversation went back and forth, then I realized it was a #robocall. I was surprised at how responsive John was, but managed to knock him off his game by asking what the #airspeed #velocity was of an #unladen #swallow. The #AI began to babble about not understanding and I disappointedly ended the call. Maybe next time, John.
