- In this video I touch on Pressure and Density Altitude and discuss the Altimeter. We look at the performance of the Cessna 172N in different Pressure Altitude conditions and learn how air temperature affects the altimeter
Another great one. We must not forget that if we fly toward an high or low pressure system, corrections must be made regularly. Thanks again Capt Skip. Let’s go on final to part 11 for the nite,
Hey Skip
I hope your safe if your at all affected by the horrendous fires going on all over your state
Stay safe!!!!
Hi Trackhoe075, Yes I'm safe, the fires are about 50 miles north of me but I have friends living close to the fires and they are packed and ready to leave if notified they must evacuate. What a horrible fire this is, seems we are having disasters all over the place.
Thanks for thinking of me and all of those who have suffered the lost of everything, and loved ones, pray for these people!

Brilliant and expository. If I get this right, airport elevation is static but indicated altitude on the plane will always varies with the prevailing weather condition at any particular time. The altimeter reading would be very crucial to a safe landing in bad weather condition that reduces visual aids.
Thanks Sir.

Great video,
I’m new to flying & learning the basics.
Question:
If I set my altimeter correct at departure airport.
And I learn what setting for arrival airport elevation level.
A) if I’m flying from Connecticut to Florida as example.
Must one write down elevations at in-between airports along my route & adjust my gauge accordingly?
Where to find a flight planner Map of potential “Obstacles” such as Mountains, Tall Buildings, Tall Towers in flight path?
Hi MIchael, Sorry for the delay in replying. So first you set your altimeter for your departure airport you will check with ATIS at the arrival airport before you arrive. Checking it at the departure airport won't help much as it may change by the time you get there, depending on the distance your flying naturally.
Having information on airports along your flight is a good Idea for emergencies and checking ATIS updates, yes on your flight you would want ATIS updates from time to time, in the real world, it would be nice to have Flight Following from a control Center and they usually will give you updates and warn you of other traffic.
Your flight to Florida is a pretty long flight so, since you are new, I'm going to assume you are not flying IFR but just getting in your little airplane and heading down the coast flying VFR. I'm also guessing you will have to make a stop or two to refuel on this flight, if I got this right it's over 1000 miles.
Here is a link to my videos on VFR flight planning that should answer most of your questions.

Hope this helps please let me know how you make out and I'll try and answer any questions you might have, It would help if I knew what airplane you would be flying :-)

@@WEHVideos Easy Question for ya in regards to MS Flight Sims- Are you familiar with flight sims? When I create a new Flight using Flight Planner from one state to another using IFR. Once I land at destination airport successfully. From there I can't seem to use the Map to setup another IFR Trip. I can open GPS and choose another location to fly to ok. Seems like the only way to do it is "End Flight" then simply create a New Flight to use Map to select proper waypoints etc. Thanks Mike
Hi Michael, I don't have MS2020 flight sim I use X Plane so I can't help you with MS and I also almost never use GPS. One thought would be to create a flight plan using the departure airport also as the final destination with the real destination airport as a waypoint so to speak and choose waypoints for to and from that airport, not sure this would work but it might, you might just have to create another flight plan as you say.Let me know if you get this figured out :-)

Hi Skip although I have not checked in with you in any of your video,s I'm just enjoying your talk through.but on the tenth video you talked about the altimeter you said about pressure at each airfield (ie) sea levels does Al the airfields have that information or do we have to find that out for ourselves. Very good videos Skip keep up the good work as I am learning as I go along appreciated by all who watch you for sure. Thanks in advance for any feed back from you or your followers.
Hi Billy Jay, Simple answer, yes you need to do this yourself.
Each airfield is at an elevation above (or possibly below) sea level (the level of the oceans). Airport elevations are expressed as feet above(or below) sea level. So if your airport was on the coast by the ocean your airport elevation would be pretty close to sea level. When you are up in the mountains your airport could be at several thousands of feet above sea level.
Since weather conditions are constantly changing you must make adjustments for "air pressure" so your altimeter displays the correct altitude (above sea level not the ground) and you need to do this occasionally on "longer" flight as you move into different weather conditions.
You get the weather information or BARO's by contacting ATIS on your COM radio. The BAROs will be something like 29.86 or 30.18 or whatever. You set that BARO number in the altimeter so it displays the correct altitude, again above sea level not the ground. If there is no ATIS available at your airport you can set your altimeter to display your airport elevation and this is pretty much the same as entering the BAROs.
You can get airport information from www.airnav.com select the "Airports" tab and type in your airport, there tons of information about your airport there. If you are flying X Plane 11 you can open the map and click on your airport and select details there you will see weather info and more. Hope this helped and was not "too" much info for you. Thanks for your question and thanks for watching.

Great explanation, one question, why was the initial elevation 900 feet, I thought 29.92 would read “0”
Hi TheHistoryCompiler, When you set your altimeter to Standard Pressure (29.92) your altimeter will display the current Pressure Altitude and not Zero. In this case the Altimeter displayed the Pressure Altitude of 900ft on the ground at Benton. There is always a pressure temperature relationship and since the Altimeter works off of air pressure the atmospheric pressure determines what will be displayed so it's necessary to adjust the Altimeter for the current weather conditions. That's why we need to check ATIS and get the correct pressure settings to input into the Altimeter. Again, in the case of this video, we needed to set the BAROs to 29.72 to get the Altimeter to ready the correct altitude. We know that was right because the altimeter indicated the airport elevation. In fact, that's another way to set your altimeter. When on the ground at your airport just set the altimeter to the airport elevation and your good to go. Hope this helped, thanks for watching :-)

Hi Skip. Could you tell me how you bring up a separate image of the instrument you are talking about in x plane11 like you do here?
Hi Mostafa, The instruments I used to enlarge the instruments is an add on for building panels for a second monitor they are not part of X Plane. There are two I use, Panel Builders www.simplugins.com/html/panel_builder.html and Air Manager www.siminnovations.com

Hi Skip, nice video. Can I ask how you managed to get the altimeter to "pop out" in a new window/overlay?
Hi Keran, Thanks hope the video helped :-) There are two apps that let you to add instruments for another monitor. One is called Air Manager and the other is called Panel Builder. I have both and use them on a fourth monitor but for the tutorials I just click and drag the instrument up to the main monitor so it would be easier for you to see. Here is a link to both sites if you are interested:

I bought one of those gshock triple sensors and it took me like a year to understand it. lol. but i didnt know an inch of mercury for every 1000 feet was a thing that helps big time. did you know the planet mercury revolves at a speed of about 32 feet a second.

I'm still confused as to why we have inches of mercury and millibars of 1013.2. Why do we do that?
Hi Spawnlord, My guess is inches are part of the decimal system and Millibars the metric system :-) Thanks for watching.

@@WEHVideos Aww thanks so much. Really enjoyed the video! 😊
Since the altimeter is set at 700 ft. above sea level, do you have to adjust for that height if the ATC orders you to 2000 ft. or do you fly at 2000 indicated on the altimeter?
Hi Don, Thanks for watching :-) No, you set the altimeter once so your altimeter displays the correct altitude. For example if you are on the ground at your airport and the airport elevation is 700ft but your altimeter shows 600ft you would dial in 700 on the altimeter to display the correct altitude to correct for the air pressure. Once set you don't need to adjust until you have flown for a while, you should check for weather from time to time to make sure you have the right setting. This would be for longer flights as the pressure usually won't change that much locally in an hour or so. In the air you should contact an ATIS and get the pressure such as 29.92 or 30.05 etc and set that value in the altimeter during your flight. Hope this helps let me know.

Hi, thanks for the video. It's some good videos you make :)
What effect does moisture have when it changes in the weather?
Hi SpotterSky, Moisture is a factor but not enough to consider or worry about 99% of the time. Naturally rain would be a factor to consider but for most flights just getting the current weather and updating your altimeter regularly is all you need to do.
You can find out more about moisture in the weather advisory on the FAA site if you want to learn more, it goes much deeper into Aviation Weather. www.faa.gov/documentLibrary/media/Advisory_Circular/AC_00-6B.pdf
Hope this answered your question.

Hi Skip. In X-Plane 11, how do I check (while flying) the weather conditions at another airport? Great videos by the way. I am sure I will have more questions along the way.
Hi Richard, In real life you would most likely have a sectional chart and on the chart you can find ATIS for airports around you so tune in to a ATIS and listen. In X Plane you can open the map and click on an airport. Make sure VFR Sectional is selected under Mode (upper right) then click the Details tab for the available frequencies at that airport, if ATIS is available get the frequency and tune your COM radio to that frequency.
Here's a tip, when planning your flight note the airports that you will pass on you flight (you want to do this for safety reasons anyway) get frequencies for each airport such as Tower, UNICOM, and ATIS that you think you could use in an emergency. Now you can get weather or if you have a problem you don't have to panic hunting for information you need to make an emergency landing.
So, if you do a little extra work when planning a flight you will have almost everything you need to avoid confusion and stress if you get off track or "things" go wrong. When this happens in real life you can't "quit" or "exit" and start over so preparation is very important.
SkyVector.com (an amazing online sectional chart) and AirNav.com are two great sites for getting airport info to help with your flight planning. Try planning your flights on SkyVector all the info you will need is available there.
Well this is probably a lot more information than you wanted but hope this helps.

Hi Skip thank's for your videos , i have a question how you do to have free windows on your screen with cockpit instruments, i have xplane 11 and OSX Mac. Alan
Hi Alain, Thanks for watching. The instruments I use in these videos are not free I purchased them from two companies www.simplugins.com their program is called Panel Builder and SimInovations, www.siminnovations.com their program is called Air Manager. They are good if you have more than one monitor, you can created a whole instrument panel on a separate monitor then just use scenery on your main monitor. I have three main monitors and a fourth I can use for a complete panel. I do not like just having scenery on my main monitors. I prefer looking out windows so I use the instruments on the fourth monitor to display instruments I can not see in the normal cockpit 3D view, this way I don't have to change my view to see the instruments. The fourth monitor is also good for placing the larger FMC or GPS instruments.

Thanks Skip for your fast answer, I'm going to bought Air manager only , because Panel builder run exclusively with Windows and I 'm on Mac OSX, at the moment I work only with a second screen.
Hi Alain, Good choice, there are a lot more instruments from which to choose and you really don't need both programs.

Hello from Austria. Thank you for the tutorial! Unfortunately i dont understand 100% how an altimeter works. Yesterday i did a desktop flight from Vienna (LOWW) to Stuttgart (EDDS). At Vienna the current pressure was 1027 hpa. I turned the knop on the altimeter to 1027hpa and got an altitude of 600ft, which is the correct elevation of the airport. At the same time, at our destination airport EDDS, there was also a pressure setting of 1027hpa due to current weather data. But at ground of EDDS, when I would turn the knop also to 1027 hpa, the altimeter would indicate a hight of 1300ft, which is correct, as this is the elevation of this airport. So what i dont understand is that why are there two different hights on the altimeter with the same setting of 1027 hpa. May you can help me with this. Thank you in advance for any help. All the best, Stefan
Hi Stefan, When you adjusted the pressure to 1027 that allowed the altimeter to displays the correct airport elevation. Since both airports had the same pressure the altimeter displays the correct elevation at both airports. If the pressure was different, say 1030 at your destination airport, the altimeter would NOT display the correct elevation it would display an elevation higher than the airports actually elevation, if the pressure was lower the altimeter would indicate a lower elevation. So it is very important to check the weather or ATIS for altimeter settings from time to time to make sure you altimeter is indicating the correct altitude. That adjustment you made, putting 1027 in the altimeter, made it possible for the altimeter to give you the correct altitude, if you don't do this your altimeter could be way off indicating an altitude much higher or lower than you are at and this obviously can be a real problem. Hope this helps.

Dear Skip. Thank you very much for your quick answer! Ok, i know now that we have to turn the knob of the altimeter to the current pressure value to get the right ALT on the Altimeter. But how does this work from technical point of view? For example at an airport with pressure of 1012hpa. I turn the knob to 1012. Outside pressure is measured by the static port. So the static port measures 1012hpa outside, which is the (imagine) current value. The altimeter is set to 1012 too and together with the values of the static port, the altimeter is able to show the right altitude. Is that the way it works? When we than fly to another location where the pressure has changed to e.g. 1016 hpa and we would remain the altimeter setting at 1012hpa, this would bring use to the following situation: The static port measures the real outside pressure. With the measurements of the static port, the altimeter is able to indicate the right Alt. The higher the Alt the lower the outside pressure measured by the static port. But in my example, the altimeter is set wrong to a lower pressure setting (1012 vs. 1016). This means, that on the altimeter there is a higher altitude indicated as the plane actual would be, due to the lower pressure setting of the Altimeter. Again, this is because the lower the pressure (in this case set on the altimeter), the higher the altitude. Understood correct? Again, thank you in advance for any response. Cheers, Stefan
........... i just have to correct myself: i´ve wrote above: "For example at an airport with pressure of 1012hpa. I turn the knob to 1012. Outside pressure is measured by the static port. So the static port measures 1012hpa outside, which is the (imagine) current value. The altimeter is set to 1012 too and together with the values of the static port, the altimeter is able to show the right altitude." BUT this isn`t true, as the static port measures the outside pressure in the specific altitude of the airport. So the measured pressure of the static port must no be the same like the current pressure of the specific weather station. This could be the solution why we have different altitudes at different airports with the same QNH setting. As the airports are at different elevations, the measured outside pressure of the static port are also different. E.g. at EDDS we turned the knob of the ALT to the right actual QNH. So the Altimeter let`s say is trimmed to the right setting. As the airport is on an higher elevation than e.g. LOWW (1300 vs. 600) the static port measured a lower pressure at EDDS (again the higher alt the lower pressure) and therefore indicates a higher alt than at LOWW although at both airports same QNH-setting. Hopefully i got it know. Sorry that i send you so much text, but I`m thinking about functionality of Altimeter for such a while and have now the feeling that i got it know. cheers.
Hi Stefan, Here's a simple way to understand this. The altimeter "reads" the air pressure through the static port and depending on that pressure the altimeter displays an altitude "based upon that pressure" regardless of the airport elevation. Since the air pressure is not the same everywhere the pilot needs to make adjustments from time to time to make sure the altimeter is displaying the correct altitude by setting the altimeter to the actual measured pressure at weather stations along his/her route. This is why pilots are "required" to report to ATC that they have the current weather settings when contacting their destination airport to make sure their altimeter is displaying the correct altitude.
Put another way, when you contact ATIS or get a weather report and you are told the pressure is 1027hpa where you are that is the pressure sensed at the static port and sent to the altimeter on your airplane.
Here is something you can try that might help. Instead of getting ATIS info and putting that into the altimeter just make the adjustment using airport elevation instead. So if you are parked at your airport and your airport elevation is 1300ft if you turn the dial until you get 1300ft displayed on the altimeter you will see that the altimeters pressure display will match the pressure setting you get from ATIS. So if you are at an airport and you know it's elevation you can adjust your altimeter by using airport elevation to correctly set the altimeter. This is handy when you don't have access to a weather station or ATIS at your airport. Hope this helps.
