Great videos. Thank you. It is important to point out that an altimeter does not actually respond to temperature. Yes, cold air is associated with lower atmospheric pressure and hot air is associated with higher pressure. But if you park your aircraft at on a ramp in the afternoon and the temp is 30 degrees and a pressure of 30.10, if the air cools down to 15 degrees but the pressure is still 30.10, the altimeter will read the exact same altitude. The “Look out below” warning is because of this association only.

@@Loves2Fly Yes, that is my suggestion. I think the speed of your speaking could be slowed down just a tad, and like you said, a bit of time between the examples would be beneficial. I think the speed with which you are "drawing" the examples is great because you are displaying everything without wasting, so to speak, time waiting to actually "see" the example. Speaking a little slower would probably allow the viewer to process what you are presenting. I did subscribe to your channel and am looking forward to watching your other presentations in the aviation related videos.

One thing that I can't wrap my head around is how the altimeter "thinks" about temperature if it has no thermometer. Instead I think cold air = higher density = more pressure... therefore it will read lower since there is more air pressure at lower altitudes. And vice-versa. Please explain if able.
@Loves2Fly

So this might help: the device has a sealed wafer inside. I use the phrase “where does it think it is” because to read changes, it must display the difference between the wafer(independent of exterior forces) and the ambient air(exterior) Hot to Cold- look out below; would that be correct in the example you gave? If you fly into a colder airmass without adjusting the altimeter, it will read higher. Hanse, the phrase “look out below “

The altimeter doesn't really think about temperature other than it was calibrated for standard temperature. The only two variables for the altimeter are the weight (pressure) of the air above the static port and the barometer setting. Having said that, the temperature questions on the FAA exam are confusing for two main reasons: One, we think of colder days as being high pressure days and warm days as being lower pressure days (which is true) AND because a bit of important information is left out: The temperature is changing in the question, but the PRESSURE at sea level is not. So when the temperature is changing the pressure at sea level, then the altimeter error is related to pressure. When the temperature changes, but the pressure at sea level doesn't change, it's a different story. So what happens when you go from warmer air to colder air, but the pressure at sea level doesn't change? The pressure levels and lapse rates change: They are expanded in warmer air and contracted in cooler air. If you look at diagram 8-3 in the Pilot's Handbook of Aeronautical Knowledge it will make more sense IF you remember that going from left to right in that diagram the pressure at sea level does not change. To go even a bit deeper. If the pressures at sea level for two given columns of air are the same, and those two columns of air have different temperatures, the warmer column will be taller than the colder column. The very top of the atmosphere is not uniform. Hope that helps.

Great video! Though I'm having trouble with something. It is well known that with warm air there are low pressures and with cold air there are high pressures. But when looking at the altimeter error (even in the Jeppssen book) it says that with warm air there are high pressures! I don't really understand. Anyone can help?
@Loves2Fly
2 жыл бұрын
Thanks for the great question! Yes, you are right there can be cold low pressure and high temperature high pressure depending on the air mass over the airport. The principles are really just generalizations to help you understand what happens to the altimeter during pressure and temperature changes. It is really a moot point if you just keep your altimeter setting accurate to the closest airport and then your altimeter will be correct regardless of the temperature except for in extreme cases.

Doesn't cold air hold more air molecules (denser) thus causing it to have more pressure? Referencing 3:23 on the video. I am very confused.

@@Loves2Fly I understand now. I was very confused about a very simple idea haha! Density is the result of air pressure and the air molecules in that column of air. As you increase in altitude, density decreases due to the lack of air molecules (less air pressure) regardless of it being cold or hot density is the result of how much air molecule is even in the air to begin with. A cold temperature on the surface will have more air molecules and more pressure than cold temperature as altitude increases. Thank you. *correct me if I am wrong here

From hi to low pressure or temperature, the aneroid wafers in the instrument expand and register a climb. If the trapped air in the diaphragm is colder is would seem to shrink. However, the diaphragm is within the heated cockpit area and its temp stays relatively the same while the outside air within the static feed cools, becomes more dense and presses on the diaphragm less--thus allowing the diaphragm to expand as in the case of lower pressure. As explained, when a climb is indicated, the pilot will fly lower to maintain indicated alt and descend to a lower true alt. Just my 2 cents.

If your flying into colder then ISA temps and coupled onto an ILS... I would expect the altimeter to read a lower altitude on the Glide slope due to colder dense air... i would say the altimeter is “under reading” your actual height. The text books say this the altimeter will be over reading? What.

@@Loves2Fly thanks for the (quick) reply!Edit; I’m stupid. Ok nvm. I have misread the question and it’s killed me. I THOUGHT they were flying the glide slope. But they are passing the outer marker as per the altimeter required height. Which means the answer they are looking for is opposite to what I wanted to give. Yes high to low look out below! This will indeed mean you are low on the glide slope and the altimeter will be over reading. RTFQ Thanks for your input! And also the video is great to cement theories!
