You are more than welcome. I finally building my RV-7. Using your tips makes things easier.

When you first apply pressure the air in the system will heat up slightly, resulting in even greater pressure. After a few seconds this heat will dissipate and the pressure will drop slightly. The result of this is that the air speed shown will drop a little, then settle. Don't confuse this initial drop with an actual leak.

Awesome video. Doing a worksheet on static system leak checks and this helped me out a lot. Although I will point out, the tolerances are not in 43.13, but in 25.1325.

When using tape to block the static port some of the glue from the tape may change the openning of the static port hole. Make sure there is no glue or add a piece of saran warp around the tube before adding tape.

Very neat! FYI: In the medical field we use that big 50cc syringe to inflate a bulb on the end of an airway tube that secures the tube in place inside the patient's trachea...

thanks for the video!

Great information. Great presentation!

Jon.. This leak test came up on the Zenith forum and the solution to the "leak" was simply covering the DRAIN HOLE of the pitot tube. Your system does not have a drain so this did not get mentioned. May help other readers and viewers to be alert to this.

great help , thank you so much

Great information.

Great to know.

excellent !

verrrrry goooood,,,

very good

My pin/drain hole at the front of the pitot (Bonanza A36) seems to have corrodeded, I cleaned it and (maybe) ome chrome broke off. It is now (not huge) 2- time the size of a pin hole, and leakas air when I blow in the front (it is ahead of the debris baffle 1/2 inch inside the pitot tube.....would this explain why my ASI is 30% to 50% my actual airpseed I saw after aborting my takeoff? Could I plug this hole to fix it?

Hi...is it true that we cant use teflon tape in threads acrosss pitot-statuc línes?

I messed up by applying too much pressure to the pitot while attaching the syringe. Now it’s stuck on 60 mph. Is the only fix to send it in? Thanks

Why did the speed go up under a vacuum on the static side? I thought the ASI worked on ONLY pressure. Thanks.

How do you find the leak?

How can we tell if the indication is accurated ?

How do you calibrate the instruments? Do you have to?

Thanks thanks thanks.....😉😉😉😉😉😉😉😉

Genial

Of course you cannot calibrate the system in this manner can you? Also if the certificated IFR system is checked an A&P IA is NOT allowed to perform the check on his own. Did you also check your mode C and S transponder? Can that be done by an amateur builder? Why are these tests even still required when we have solid state equipment installed? I could see it back in the steam punk days and vacuum tubes, but not any longer. It just another expense without much justification. None of these tests were around when my plane was built.

Dear Sir, I liked your video. However, there are a few things that you did and stated that are incorrect. These discrepancies can cause damage to your Instruments and/or get you in trouble with the FAA. 1st - The absolute pressure inside the Pitot system must always be equal to or greater than the absolute pressure inside the Static Systen or damage to the Airspeed Indicator will result. 2nd - All aircraft wishing to fly IFR must have their Static tested and certified within the preceding 24 calendar months. 3rd - All Aircraft equipped with mode C transponders must have Mode C Altitude Data Correlation Tests performed before the first flight.
