It always makes me laugh when we fly out of Heathrow on a hot summer day wearing tee-shirts and shorts. 45 minutes later, everyone bursts out laughing at the announcement over the PA. "We will be landing at Cork airport in about 10 minutes, the weather is overcast with light rain". We walk out of the airport to be met by people holding umbrellas and wearing soggy rain coats. They look at us as if we are stupid.

Well to be fair it is a specific subset of weather, and almost exclusively the current weather or a 12-24 hour forecast with information specific to flying. While the news is covering more general weather up to a week out and explaining it to the general public. Kind of apples to oranges.

I used to live in Phoenix, Arizona and witnessed Sky Harbor airport being completely closed a couple of times due to the excessive heat. At the time I thought it was because of the heat's impact on the planes' tires and brakes, but did not make the mental connection that the heat would also negatively impact the planes' performance. I love these videos--they're great learning tools!!

Had almost 2 hours of waiting on board the plane in Dallas just a few weeks back, on a hot day. Since I watch Mentour, I was wondering when they would start an APU. I heard what I figured was an APU coming on, and then the pilot (who kept us informed well) announced that "we've started up an...an energy unit to help cool you all off..." I was pretty sure the stutter around "an...an" was his trying to avoid saying jargon like "APU."

[@Colaholiker]

I have experienced the "hot and high" problems flying out of SLC (Salt Lace City, Utah) a while ago. Even though there were empty seats they announced they could not take any standby passengers since the plane would have been too heavy for the current weather conditions. The other thing you mentioned that I also find very important is a pilot giving information to the passengers. On a recent flight in the US (small regional jet flying in the colors of a large airline), there was a technical problem before take-off. (The batteries of the plane didn't charge off gound power or APU power.). Not only did the captain make an announcement, describing in full detail what the problem is, giving analogies to technology the passengers are more familiar with (the charge indicator on your car's dashboard), he also gave an estimate how long maintnance would need to fix it, but, what I found really special, he did so by coming out of the cockpit and standing at the fwd end of the aisle and announcing through the flight attendant microphone. (I can understand that you don't do this in flight for security reasons, but this was on the ground with the doors still open.) Much better communication than just "hiding in the cockpit" and mumbling into the PA mic. ;-)

[@geoh7777]

Yes, flying an aircraft is harder in the hot summer. Therefore, I have voluntarily absented myself from flying in the summer in order to do my part in helping to lighten the aircraft.

I literally was just on an Hainan Airlines A330-300 with a broken APU flying from Shenzhen, China to Auckland, New Zealand. It was so hot in the cabin that some people were feeling unwell. The pilots then started engine num. 2 and we were fine afterwards.

[@damo7667]

I live in Arizona. There have been a number of occasions when flights have been stopped due to excessive temperatures. 48/49C and the smaller planes are halted. 50C and the whole airport shuts down from what I have heard. I was not here for the 50C so only have anecdotes from natives. It's fascinating that nature can have such extremes that what is taken for granted in most places can have such major effects elsewhere.

@@coopergates9680 Tucson or Vegas are more likely. The TUS airport is usually 5+ degrees cooler than PHX. I think Sedona's runway is too small, and Flag doesn't have the infrastructure to cope with dozens of planes.

[@coopergates9680]

@@geonerd If they could redirect as far as Vegas, they may as well call on Albuquerque or El Paso. Cooler still

[@herestoyoudoc]

​@@coopergates9680 the density altitude issue is not as bad for landing as it is for takeoff--so runway 8/26 can probably handle it even at 50+ C. It is 11,489 feet long so plenty of room to stop even for a big plane. When landing, planes are lighter on fuel so that helps even more. Holds may be needed to handle reduced capacity but this is offset by making all runways available for landing. Ground operations must be in shape enough to make sure planes can get to their gates quickly, otherwise you might barbecue the passengers--but again, this is offset by the lack of departures.

[@funkyzero]

Coming back from Keys with family last summer, I was on a commuter-sized jet (sorry I can't remember what it was now), and we were delayed on the ground for FOREVER because of an A/C issue... Once airborne, water started pouring out of the ceiling panels, soaking my hair and shirt. This went on for the entire flight. The only grace was that the water appeared clean and didn't stain up my clothes. I suppose I should have said something, but I didn't want to stress the poor flight attendant anymore than she already was... she was a wreck already with everyone bitching and complaining about the delays.

Affects Chicago O'Hare quite a bit as well. Summer used to be when most of the delayed aircraft were from there sometime earlier in the day. I don't see that as much, so maybe airlines moved flights to other hubs, or avoid going in or out of O'Hare in the summer afternoon.

13:23 Aaah, that‘s why I sometimes feel that maneuver during the landing. I hear the engine spinning up and down, up and down, and more G forces, less G forces, more G forces...

Having grown up in Australia, I have experience with asphalt absorbing more heat than concrete pavements. We could walk barefoot on cement but had to avoid, by jumping over, or walking around asphalt. Wouldn't this also have an effect on aircraft tyres? Thanks for the video. 👌

[@patriciatreslove4449]

Great to keep the passengers informed about what is going on.

[@Eternal_Tech]

There should be a law that once the interior temperature and humidity level of an aircraft reaches a certain point that is dangerous for human health, the pilots and/or airport should be required to do what is necessary to cool down the cabin. If this includes activating the APU or running one or more of the engines, so be it.

I was sitting right by the opening down to the cargo area. It was the condensed moisture that set off the smoke alarms. Still made for a tense flight. Really enjoy your information.

[@sandramccusker5520]

I did wonder why passengers were boarded if there is a known delay. Makes sense that, if there’s a chance to shorten the delay, they need the people onboard and ready. It is awful, though, unless the pilot lets people visit the cockpit while they’re having to wait. That is a fun distraction I’ve never had happen in the states, only in Europe. Maybe it’s not allowed in the US? Flying into Las Vegas is the worst for that convection turbulence! Turbulence coming over the mountains, turbulence from the heat rising off the valley floor...it’s a thrill ride landing at McCarran. The puppies are adorable! Nice to see Molly has a chance to leave the basket now that they’re getting bigger.

[@oxigenarian9763]

I've been at an airshow when they closed down the airport because of ambient temps. I live in the high altitude desert; if there is a low pressure front coming in and the temps are really high, the air density is comparable to being at 10,000 feet or higher. Physical exertion becomes a real challenge and flight physics at that altitude have to be quite different!!

[@sharoncassell9358]

I drove in Fresno valley in California. While going up the mountain the altitude is 3700 feet and I could hardly breathe up there. Las Vegas and Arizona are very arrid also. There's turbulence but no rain.

[@oxigenarian9763]

@@sharoncassell9358 If it was hot then, the actual air density is a lot lower, that may be why you felt out of breath. The other factor we deal with here in the high desert is humidity. If the humidity was as low as I suspect it was, that can quickly dehydrate you through expiration and that feels just like high altitude sickness.

[@igorbednarski8048]

​@@sharoncassell9358 it sounds like placebo - 3700 ft is barely over 1000m, that's way too low to feel the effect of altitude. It takes at least 2500-3000m before you start to feel any noticeable effect. For context - typical aircraft cabin pressure is equivalent to 8000 ft (1800m) and people don't get altitude sickness in planes.

[@wotan10950]

Fascinating, as always! Although I fly often as a passenger, I can only recall one instance where the altitude/temp was an issue. It was an American MD-80 from Albuquerque to Chicago. It was a blistering 112F. The runway is nearly 14000 feet, but when we rotated, the wings shuddered quite violently. I had never experienced that before.

Another fantastic video Petter!

[@Apeing510]

The fact that the Aircraft needs an APU or an engine to be running in order to use the AC is ludicrous, especially when so much emphasis is put on reducing CO2 emissions nowadays. They should be able to run off ground power. It also makes life a lot worse for us Ramp Agents. In the summer we already have to deal with doing a very physical job of loading/unloading the bags inside a hold that feels like an oven, but with the APU running we can't safely take our ear defenders off so it's even harder to stay cool.

[@peterkolesar4020]

Know that feel brother :|

[@bdw66]

That was my question... Why can't the AC not be powered by electricity from the airport?

[@greg42058]

​@@bdw66 I might be mistaken here, but this is because the Pressurization Air Conditioning Kits (PACKs) use bleed air from the turbine of an APU or an engine in order to provide pressurized air. This air is then "conditioned", i.e. mixed with air inside the aircraft. On the ground the same system is used, but an additional cooler is required, since the air outside may not be cold enough. Some of the newer airplanes (e.g. 787 Dreamliner) do not have bleed air system, so they must solve this somehow differently. Perhaps on these planes you can run the airco from ground power?

[@Apeing510]

@pilotguy707 So if you can run the AC off Ground Power, why do so many pilots wait until the passengers have disembarked before they shut off the APU? Likewise, why do they start the APU as the passengers start boarding instead of a few minutes before pushback? Not only is it harmful to the environment, but it's extremely unpleasant for ground staff working around the aircraft and I imagine not too fun for the cabin crew stationed at the back door either.

[@Apeing510]

@@greg42058 The Dreamliner uses an all-electric A/C system. It also needs two 400Hz 200v AC ground power connections where most large aircraft only take one. Plus, if the APU fails rather than the traditional Air Start unit, it takes a third ground power connector to start the engines.

A passage from his memoir *Fate Is The Hunter*: "Now, in August, the route and particularly the sky above it have begun a change. The etched clarity of vision is gone and the mustard-colored fields are often nearly obliterated by haze. The winds are stagnant and sullen, yet the air is annoyingly pitted with a multitude of minor vertical disturbances which sicken the passengers and keep us captives of our seat belts. We sweat in the cockpit, though much of the time we fly with the side windows wide open..."

When it comes to lower air density caused by heat, where I live, the main airport in the city was temporarily shut down a few times in the past because it was too hot. And that airport is one of the ten hub airports for American Airlines and formerly the home base for US Airways when it was a thing.

[@9HighFlyer9]

It's also a crew base for Southwest

[@markg7963]

Phoenix Sky Harbor airport, I think you are referring. Interestingly, that shutdown wasn’t an airport shutdown, it was specific carriers that did not have charted takeoff data high enough to calculate the takeoff data. So, they couldn’t just guess or extrapolate, causing them to delay things until it cooled off. I can’t remember for sure, but I think the temperature went over 120 degrees those days. Since then most airlines have charts with a larger temperature range, and more sophisticated systems to compute data more accurately.

Final was worse as the wind direction was shifting and these air ports are bordered by forest that causes mechanical turbulence, and one has short final over deep cold water enhancing the change from down draft to updraft. The wind sock at one end was a left crosswind and the windsock at the other end was a right crosswind. Completely clear sunny day.

I thought it's not allowed to fly without APU. Chesley Sullenberger couldn't execute ditching of his A320 succsessully without APU. So it's for me very strange when Mentour says that it's not a problem to fly without operable APU

[@gerryino]

Also doubtful about this. In case of engine failure won't you lose all electricity in this case?

Not true - look for info about RAT turbine

Flying - during the summer - to the south of Italy (it seems a lifetime ago) the pilot was ALWAYS using reverse thrust when landing. And I couldn't figure out why. Until you explain that aircraft brakes do require a long time to return to their operational temperature, and that explain everything. Which brings me to the next question: I have seen in some top quality cars a fan build in the brakes, to facilitate cooling. With airplane brakes handling some MJ of energy, why there isn't a provision for their active cooling? Already the tires, at zero RPM when landing, take a serious beat every flight; the brake pads too, by getting close to incandescence at every landing? I'm sure there is a proper maintenance turnaround for brakes and tires, but why is not practical to keep pads cooler so an airliner can take off soon after it has landed? Thanks for the outstanding video. I'm not a dog person; but your pets have some moviestar qualities with them, for their awareness of their role in the overall picture. Regards,

[@starstencahl8985]

As far as I know, there was a concept of a fan that made the wheels spin before landing by using the outside air. It didn't get implemented throughout the industry, because it apparently wasn't worth it. It's always a lot of extra cost and effort to get something registered for aviation use. And even if you wanted to do so, every little gimmick is still extra weight that needs to be dragged around and costs fuel without paying like an additional passenger. Also, every part has a risk of breaking/malfunctioning, how small it might be. It's always a question of cost and benefit and it seems like those extras aren't worth it for the manufacturer or airlines.

Very good episode and education on the specs of flying whats involved .

[@bobbypaluga4346]

Great topic, I live in Phoenix and fly 2-3 times a week on commercial carriers as well as being a long time pilot. This time of year daily temps are 112-116 degrees. The charts only go up to 110 degrees, Airlines will play it by ear, but baggage will be removed passengers deplaned. Heat waves coming off the runway make it a little harder to land your small aircraft. We are subject to ATC delays n Phoenix when LAX has issues. The last week in July and all of August brings the monsoon season with the nasty storms you describe.

13:30 this convective turbulence is so pronounced on Final Approach into Las Vegas McCarran Intl

[@Trojans175]

I think the mountains contribute to that too

[@ChrisTimberlake]

On final and take-off. They're continually changing the runway take-offs to count for this. Summer/Spring months you depart to the east, Summer/Fall you depart to the west. Approach is visa-versa.

[@ChrisTimberlake]

@@Trojans175 Mountains contribute but in Summer/Sprint they usually route you either coming in from the west, where you miss the mountains. Or from the NE -> SE Runway which you drop down to 5k after the mountains. Which makes it more bearable. Flew in/out of there every Mon/Fri. HATED IT SO DAMN MUCH.

[@randywilliams4325]

Denver is good for this too.

[@wotan10950]

Hobo G I’m sure it just depends on the day/weather. I’ve flown in and out of Vegas and Denver, and each time was smooth as silk.

[@bernardofitzpatrick5403]

Wow! had no idea about these problems! very informative. Love the dog :-D

[@mrvwbug4423]

Hot and high departures are definitely a big thing in the western US. On a hot day in Denver, the 737-900ERs actually have to use the 16,000ft runway to get off the ground (16R/34L)

[@bobbimke82]

Plus, also, too 8:43 ["if there's not enough runway, we will not take off"] ==> "Physics! It's NOT just a 'good idea'. It's the LAW!"

I am terrified of flying. But these videos help me keep my mind at ease. These well explained videos that depict would be horrifying conditions, helps quell my fear of my upcoming trip to California.

[@kekkelpenneypeckeltoot5700]

Love the reminder to not shoot the messenger! I was surprised you didn’t mention high heat and the inability to fuel the plane. 3 times I’ve been on delayed flights because the outside temperature was too high to refuel. Or maybe that’s just what were told!

[@balajisharathkumar9753]

you told about the air pocket feel I got the same feel while landing because of airbrake and reducing altitude fantastic and really useful video

As a passenger sitting in the back of the plane and basically ignorant of external circumstances going on external to the aircraft, this video, is something every passenger should watch. When you understand why something is happening, you are more tolerant of conditions in the plane. Knowledge may not make it more comfortable, but it helps to know that discomfort will be temporary and relief will come. Thank you for this video!
