I didn't realize the pitot was heated the entire time the engines were running. I figured it was like anti-ice boots, or fluid - just used as needed. I also didn't know where the AOA measuring device was. I appreciate the info, Shaun!
Every aircraft I worked on, the pitot heat had to be turned on. Maybe on some newer automated aircraft, but then those fancy systems tend to drive good aircraft into the ground.
Fantastic - welcome back, buddy. Here in the UK we are 'locked up' and your Tech Tuesday videos are a welcome relief from complete boredom!!....love the new 'facial hair', by the way !! PLEASE - stay safe, and look after all those you love.
Sorry to hear your stuck at home. If it makes you feel any better, I only leave the house about once a week. I'll try to get some entertainment your way in the mean time. Stay safe over there!
Cool! Really enjoy the nuts and bolts stuff on these airplanes along with the flying (of course). I learned that the derivation of pitot -- like aileron, fuselage, nacelle, empennage, etc., etc. -- is French. They had a lot going on in early aviation, apparently. Also learned that pitot is an eponym referencing its inventor, Henri Pitot. Ha! Thanks Shaun.
Thanks for taking the time to work in a Tech Tuesday with everything you have going on. Congratulations on your new position. Even if we don’t see you as often maybe your family will.get more time.
thanks shawn. i started to do a tech tuesday vidio for my grand dauughter today on her car that we got for her hs graduation she lives in hi and is going to school in va this fall. i am using marco polo dennis
Timely video particularly with the 737 Max issues. Did some regulatory work regarding ADS-B and related FAA initiatives. Had and interesting meeting before I retired with the regulatory authority. I wonder how much NextGen initiatives will make those probes a backup source. TCAS and Oceanic navigagion may end up being greatly improved as well. Finally, all the additional weather data aloft are already helping with weather models. All cool stuff. Glad to see the videos coming back! Congrats on your promotion.
Nice one, when I go helo skiing the brief ensures we stay away from the pitos. But further thanks in explaining the other hanging red flags I see on early flights. Congrats; thanks for keeping it going.
the cover on the pitot also keeps your head scar-free, as on some planes their low enough to run your head into, especially some GA aircraft. Been there done that ouch!!
Great tech Tuesday Shaun. Yes I have clipped that pitot tube on a Cessna one time, lol note ONE time. So glad you are back Shaun. Keep up the great work. 👍👍👍
I do not want to annoy anyone but remember that the pitot tube measures dynamic pressure, which is not airspeed. under certain atmospheric conditions IAS, to be more accurate CAS will indeed read airspeed TAS (true airspeed). thanks for the quick explanation by the way, I wish I could be a real pilot. dreams of my dreams...
@@barrygrant2907 That is not true, dynamic pressure affected by density. density, (of the air) affected by: -temp -air pressure -and humidity for example: when it is hot and moist day at high elevation you will have to fly faster through air (TAS) to get the same dynamic pressure (IAS) due to the reduce density versus a cold dry day at low elevation.
@@may4092 Impact plus static, the static is the air density. I worked avionic instrument systems for 20 years, pitot-static systems being a major part of it.
@@may4092 Didn't say that at all. "True" airspeed factors in temperature. "Indicated" airspeed, based on air pressures alone, does not use temperature.
I wonder if a small plug would be another way to keep bugs out of the pitot tube in addition to the cover, like the static ports. Thanks Shaun. Stay healthy. Love the C8 reply lol.
When you pointed out the pitot tube, you didn’t indicate where the drainage port is located. By the way you explained what happens when pitot tube ice over and air speeds remains where the blockage took place suggest the pitot drain must me actuated by a valve. On GA pitot tubes have a drainage port behind the pitot tube and when ram air is blocked airspeed will indicate zero.
Does the angle of attack indicator sensor flutter in the wind!? Is seems to move so freely that any turbulence or crosswind would cause that thing to go haywire
When it comes to the altimeter, what part of the plane is at the altitude? Is the reading at the top of the plane, the bottom of the plane or center line of plane.
The altimeter compares the outside pressure to the QNH you get from ATC. From 29.92 to 29.93 is several feet. Radio altimeters are usually located near the tail and are calibrated to match the main landing gear wheels, during the flare.
There is actually a very small drain hole on the bottom of the pitot tube, but I didn't want to get into that on the video as it might get a little too technical. With that in mind, for the airspeed indicator to "act like an altimeter" both holes of the pitot would have to freeze over.
Shaun, Do the instruments that monitor fuel economy rely on those probes, as well, or do they base it on some other things ? I would imagine your onboard computers do a decent job through your inputs from external information sent to you. Wouldn't the artificial horizon indicate angle of attack also? Pardon my ignorance, the last time I took flying lessons was in the early sixties. Cheers, Rik Spector
These probes actually send their data to the Digital Air Data Computer, which converts the information to a digital signal. It is then sent to many different instruments and computers for use. As for the artificial horizon, it will tell us the pitch of the plane compared to the actual horizon, but it does not know the relative wind direction, so it cannot give us Angle of Attack.
@@CorporatePilotLife Thank you ,Shaun. I try to ask questions which are relevant to your Videos. Sometimes I reply just foe the "Elavate" :) Cheers, Rik
A friend who’s a CRJ driver said a guy once poked his head around the cockpit window as he deplaned to wave at the pilots and his tie melted on the hot pitot tube 😂

Quote of the day: “it tells us when the plane is about to stall...which is a bad thing.” Just love this channel! Welcome back, Shaun and Tech Tuesday.
Nice to see things getting back to normal
Great Tech Tuesday video Shaun!!! Thanks
Love these Tech Tuesdays! Glad to have them back...
Glad your back

Now you're teaching me stuff...thank you!
I Always enjoy the technical chat.. please do keep them coming as you have opportunity.
That was an awesome Tech Tuesday. Thank you sir.
One of the most important of the pilot’s visual pre take off inspection is to examine the pitot tube(s). Thanks for showing us why.
Very nice explanations Shaun. Thanks and it's great to have you back.

Thanks you for this information
Great video Shaun. Good briefing!😁
Good job on the vlog as always!
Cool! Always wondered about those things but not anymore. Thank you sir.
Cool. Thanks Shaun. I did learn a few thing! Much appreciated. Hope work is well.
These are great
You should do a video of common things you have to deal with as DFO

Pitot pressure is air impact pressure plus static pressure, but it does not take into account air temp which will affect true airspeed indication.
@@barrygrant2907 That is not true, dynamic pressure affected by density. density, (of the air) affected by:

@@barrygrant2907 let me get this straight. basically what you're saying here, that temperature does not affect dynamic pressure?
@@may4092 Didn't say that at all. "True" airspeed factors in temperature. "Indicated" airspeed, based on air pressures alone, does not use temperature.
that was really interesting!
Also important to note: The right side usually has another set of pitot tube and static port. Some aircraft even have two on the left for redundancy.
Awesome
Thanks a lot for the video.
Good info...
Thank you Shawn!!
Glad to see your safe and well! Good and a little strange at KROC to LOL. That Hawker looks like it's been around awhile? Be safe.. --gary
I wonder if a small plug would be another way to keep bugs out of the pitot tube in addition to the cover, like the static ports. Thanks Shaun. Stay healthy. Love the C8 reply lol.
Have you done a Tech Tuesday vid on Jet anti-ice / bleed air? Keep it up!
I learned
When you pointed out the pitot tube, you didn’t indicate where the drainage port is located. By the way you explained what happens when pitot tube ice over and air speeds remains where the blockage took place suggest the pitot drain must me actuated by a valve. On GA pitot tubes have a drainage port behind the pitot tube and when ram air is blocked airspeed will indicate zero.
Hello
thank you for the video
do you have any idea about what they do for anti Icing
DO you have any picture or video from cut view of this probe?
Great video, glad to have them back.
What is the watch you're wearing in this video?
This is my Garmin Fenix watch. The Breitling is in the shop for service...I miss it already.
It's worth reading about Air France 447 and Birgenair 301 to find out what happens when things go wrong with pitot tubes.
Very true
How would you clean out debris without damaging the sensors? Full disassembly?
My understanding is they remove the line from the inside and blow outward...
@@CorporatePilotLife Yes. The worst culprit for plugging pitot tubes is wasps, mud dobbers to be more specific.
Is the angle of attack heated as well....not sure if ice that can build up on it
Yep...mainly the base to keep free rotation.
That watch is cool but the size of a manhole cover. Where can I get one? 😎
LOL...that's my Garmin Fenix GPS watch.
Shaun, Good summary of the pitot-static system! Does the Hawker have dual pitot tubes and/or static ports? Thanks for another great video!
Yep...pretty much dual everything on this plane.
Hey Shawn... Good hearing from you and thanks for the tutorial Sir! BIG-Job... has that adversely effected your PIC Time ? thanks ';-)
I'm still doing plenty of flying, but I get to pick the trips a little more now.
What is the needle on the left side of the AOA indicator for?
That is an adjustable setting to create the Vref window on the right side of the indicator. We usually leave it set to 1.3
Great Tech Tuesday, thanks! Do some aircraft (commercial airlines) have any redundancy?
Most do...
Does the angle of attack indicator sensor flutter in the wind!? Is seems to move so freely that any turbulence or crosswind would cause that thing to go haywire
At low speeds it may bounce a little, but not much at all as long as we have some airspeed on it.
When it comes to the altimeter, what part of the plane is at the altitude? Is the reading at the top of the plane, the bottom of the plane or center line of plane.
The altimeter compares the outside pressure to the QNH you get from ATC. From 29.92 to 29.93 is several feet.
Radio altimeters are usually located near the tail and are calibrated to match the main landing gear wheels, during the flare.
Thank You. I learned something new today. Great videos, really enjoy watching and learning.
Shaun - what video editing software do you use?
I recently switched to Adobe Premiere Pro. I used to use Pinnacle Studio, and have been very happy with the switch.
How does the pitot tube get rid of water/rain being pushed through it?
*when flying
There is actually a very small drain hole on the bottom of the pitot tube, but I didn't want to get into that on the video as it might get a little too technical. With that in mind, for the airspeed indicator to "act like an altimeter" both holes of the pitot would have to freeze over.
Corporate Pilot Life thanks for the explanation
Have you ever landed at SXM?
Yep...I think I have a video on it too!

Better than his chin I suppose...LOL
Corporate Pilot Life 😂 for sure 🙈
How old is that plane?
This one is about 15 years old
👋🏻KSRQ☀️🌴🇺🇸🛩🦠
Where do I send my resume to.
Hey Shaun, does the Hawker have a redundant system like the GIV? And does it measure static air temperature or total air temperature (SAT/TAT)?
There is a redundant AOA vane and pitot tube on the other side of the plane.
Also, I believe the measurement is TAT, but the computer has the ability to convert to SAT.
A C8 needs an Airspeed Indicator
A C8 needs to be in my garage...LOL
Hey Shaun I was watching a different aviation channel here on you tube and heard an old call sign Presidential 1 Vamoose
