Comment on Cold Weather Altimetry – Cold Weather Flying by Robin Maiden

Robin Maiden — Mon, 21 Nov 2011 15:13:25 +0000

The air is just denser/thicker when it is cold. The atmosphere is literally less tall when it is cold. So, when the you stand on Mt. Everest, on a very cold (ISA minus 30) day, you are closer to the pressure of space than on a hot day (ISA plus 15). An altimeter on the mountain would indicate very high altitude on the cold day and very low altitude on the hot day even though it hasn’t changed its position.

Altimeters described as “temperature compensated” have been designed to maintain the same “ratio” between pressure and indicated altitude across a specified temperature range. This is an engineering feat to make sure the mechanical parts don’t induce errors in the ratio when they expand or contract because of temperature. A “temperature compensated” altimeter does not adjust for different densities of the atmosphere. How could it know? It only “knows” pressure.

In the age of GPS, have you noticed the discrepancy between GPS altitude and indicated altitude? Even on a 29.92″ standard day? This is exactly what I’m talking about with cold weather altimetry.

I understand everything that I have read so far, but what I can’t find (or verify) is what is the physics (or chemistry) of the problem? Is it a molecular driven issue due to the cold air on the aircraft metallic instruemets, or is it a density driven issue due to the extreme cold/thick?

Too many timid souls have been lost because they were unable or unwilling to challenge things that made them uncomfortable.

Thanks for asking. This is pressure altitude.

Question, so a newly corrected DH for cold temp, is this now a pressure alt reading or a density alt?

I couldn’t agree more. Strategic application of a tool should win over “Hey, That’s cool! Let’s do it too.”

Too many people definitely use the wrong medium for communication. However, the other side of the coin is when I see people using social media tools without a plan. Choose the right tool for your audience and don’t just use a technology because it’s trendy.

Comment on Social Media Wins in Senate Race by natalie maiden

natalie maiden — Sat, 24 Apr 2010 18:22:17 +0000

Hi,

This is clearly what happened, and the arrogance of the MA dems (yes I am a dem). Pres. Obama’s team was really the first to leverage social media and I think it is part of why he was elected. I will the myriad of other reasons for another discussion.

I am curious how we can educate the youth that what goes into the air will haunt them forever. Thoughts?

Ian Edwards — Wed, 22 Apr 2009 06:02:51 +0000

I am flying Glf 550 aircraft in Either Russia or Dubai, so see the two problems, often on the same flight.
The Russians in most airports do not compensate for the low temperature on the below TL numbers, also in the very cold partsd of Russia, there are often severe temperature inversions at 3000 ft, so the temp can change from -40 to only -20 on the approach, in a matter of 100 feet or so. The auto throttles dont like it at all.
Your remarks about alt busts due to over warm days is also valid, and I will ask friends in DXB ATC how this is catered for here.

My original posts on PP were related to the hot corrections, and you clarified that for me.

Thanks.

Ian

Robin,

I am a military flight school instructor and would like to use your video. If I can get your permission to use it, I want to embed it in a powerpoint slide for a presentation I will us at a safety stand down to enhance flight safety for our future military aviators. Will you email me the flash video so I can put it into my presentation? Full credit will be given to you and I would use a direct link if I could guarantee that I would have internet access every time I give this presentation.

Thank you in advance, I know how busy you must be.

Bill

Comment on Corporate Culture Change and New Media by Keith Burtis

Keith Burtis — Tue, 02 Sep 2008 21:47:20 +0000

Robin. Very Thought provoking. Have you thought about entering the trance of the groups you are effectively trying to persuade? I would think that trying to change peoples minds, habits, and decisions would be similar to swimming upstream. Comparatively, entering the trance of your target market or group is like swimming downstream.

I am a woodturner and artist. Many of my clients never knew what woodturning was before I introduced them to it. Why would they care? Why bother looking?

An example: My targeted circles of people are interested in tech, geeks, programmers, social media, etc….

I create a line of art called “We are all Connected” and the line of art sells out in record time.

Why? Because I have entered the trance of the people I have targeted. I have created an emotional and intellectual bond between their trance and mine.

Approach your market at their level. Enter their trance, no matter what that might be, and you’ll have a much better chance of persuading that group.

Comment on New Media Expo 2008 – Wrap Up by René van den Bos

René van den Bos — Fri, 22 Aug 2008 18:39:27 +0000

Hi Robin, for sure it was a great pleasure meeting you at the New Media Expo. I sincerely hope we are able to elaborate the energy we created together and start the conversation about the use of new media in the corporate environment. According to our experiences it is a fantastic, efficient and engaging communication tool with lots of advantages: an effective communication platform for complicated processes (e.g. change management, strategy implementation), cost beneficial in comparison to printed media (who reads the company magazines, really?) and creating pride and loyalty amongst employees. Soon we will publish some interesting data on one of our projects (internal podcasting). Stay tuned at our blog digiredo.wordpress.com…

Hi Robin,

Totally agree with you. It was different than other years (anyway, the previous year we went to). I did miss the Libsyn party but got other things in return, such as great contacts. I hope Tim and Emile continue to organize this event and all kudos go to them for this year’s organization.

Internal podcasting is the way to go. Just got today some interesting data on another internal podcast we did. We’re definitely on the right track.

Keep up the good work within Delta.

Regards,

Erik (DigiRedo)

Comment on Problem Solver vs. Symptom Sleuth by admin

Thanks, Tom. A positive correlation does not necessarily point to a certain cause and effect. Many people forget that. There can be a bigger cause with two correlated results.

Comment on Problem Solver vs. Symptom Sleuth by Tom Roberts

Tom Roberts — Tue, 24 Jun 2008 02:21:57 +0000

Great post Robin. As an INTP with an engineering degree, I consider myself a skilled problem solver. Lately, I’ve been looking at a related issue – understanding the cause vs. the effect. I see many places where people look at a set of data and proclaim a certain conclusion, but fail to critically look at the cause vs. the effect. While it is important and desired to know how to solve problems, it is even more valuable to understand if you are looking at the cause of a problem, or simply quantifying the effect.

Robin, beautiful blog sir. I found you through CC’s site and just added you to my twitter stream. I am also going to Podcamp Boston 3. My first podcamp was Toronto this past February and i loved that. I have been looking forward to the announcement of Boston 3 ever since. The Harvard location really takes the cake for me. Thank you for the post, nd thank you for the great links. You have a new subscriber.

Comment on Cold Weather Altimetry – Cold Weather Flying by Mike Maher

Mike Maher — Wed, 26 Mar 2008 06:30:38 +0000

Hey Robin,
Nice explaination. The real test comes when you are not flying a precision approach with a glideslope (although your barometric altitude will be lower for cold weather, but not by much at 200 ft HAT).

When you’re flying a cold weather non-precision approach with no glideslope (GPS synthetic or otherwise), your real threat is at the intermediate fix altitude, vs the IAF altitude (1000′ ft terrain/obstacle clnc) or the MDA (less deviation closer to the altimeter source, and 250-300 ft obstacle clnc).

At the intermediate fix (500′ terrain/obstacle clnc) you have the most altimeter deviation with the least TERPS clnc criteria, and therefore, you have the worst of all possible scenarios.

I’ll e-mail you some of the cold wx research I did at the USAF Advanced Inst school.
Mike
