How To Set the Altimeter | Two Private Pilot FAA Written Exam Questions
Вставка
- Опубліковано 6 вер 2024
- Two questions from the FAA Private Pilot Written exam are shown with explanations, but some basics of setting the altimeter are shown first. Ever heard of a Kollsman window? In this video, you will find out why it is named a Kollsman window.
An altimeter can be set using automated weather, but if automated weather doesn't exist at the departure airport, field elevation can be set into the altimeter. Both methods are shown as well as where to find automated weather frequencies on a sectional chart and in the FAA Chart Supplement book.
If you are preparing for a Private Pilot checkride, this oral exam guide is a must buy. I used it myself back in the 90s and had all my students use it to prepare for checkrides when working as a Flight Instructor - amzn.to/3Cgbl7X

Thanks for posting. There is a lot of explanations out there on youtube. This one actually makes sense!
I feel like there should be two knobs, one for pressure and another one for the altitude/height calibration.
If both of them move with one knob, the Kollsman window is redundant. I thought that the purpose of the window is to adjust the varying pressure with regards to temperature and humidity.
I wish I would've invented the barometric altimeter... but I'll just settle for knowing how to set one I guess 🤘great vid as always my friend!
If you invented it, the Kollsman window would be called what?
@@thecorporatepilotdad hmm, not sure, but I do know I would’ve made it so every time I’d adjust it “under pressure” by Queen and David Bowie would play.
@@skytation clever!
@@thecorporatepilotdad Right? I was just trying to be funny, but now I think I'm going to program that to happen on mine in the home cockpit 🤣
@@skytation that would be quite entertaining during your streams.
altimeter readins important to measure elevation or runway/airport.. must be in the Himalayas
How about things such as density altitude and stuff?
Not a FAA question but an altimeter question. You can ignore np.
Flighing the TBM higher than 18,000 feet (Class A airspace). You set the PFD Kollsman to 29.92 which is tied to mode c reporting. But, what about SAM Kollsman setting? I like to keep it set to my real altitude. That way in the case of a rapid descent I know my real altitude. Do FAA regs allow the pilot latitude to set the standby altimeter?
You could set local altimeter in the standby but the standby altimeter isn't very accurate at high altitudes and that altitude can't be used for anything. There would be time to set the altimeter to the local altimeter setting in an emergency descent. ATC would give the altimeter when descending below 18,000 or the pilot could ask for it and set it quickly.
@@thecorporatepilotdad Thank you
I have a question. But first let's agree upon the following:
- the air pressure is the pressure a column of air 1m2 wide exerts ... or put differently, it's the weight of a column of air that wide and as high as it goes...
- the heavier the air - higher the pressure it exerts
- the air gets heavier when it's full of stuff... water molecules, dust, smog, volcanic ash... whatever.. but mostly it's water vapour.
_______________________________
Question: how come we call it low pressure when the sky is cloudy since that's when the air is full of water vapour and thus the heaviest!?!?
It may seem counter-intuitive but the density of an air parcel is inversely related to its quantity of water vapor. Assuming constant pressure, temp, and volume, the air parcel with a greater amount of water vapor is less dense. Dry air molecules have a larger mass than water vapor molecules.
👍🏻 now explain the concept of “from a high to a low look out below!” 😁🛫
