@jamjake01 @Aviation_Movies Which direction they coming in from please, is it usual via Yeovilton?

@Aviation_Movies Also sounds like they are both going to do 2 circuits

Speaking of oil, when leaving Athens last year, the hotel gave us going away presents. One was a small jar of olive oil (center).
It’s just sooooo clean & smooth. I literally just put a little on my tongue occasionally for the taste…I don’t dare waste it cooking. I’d been using the oil on the left & it has a bitter aftertaste that I suppose I didn’t mind before, but now I do & imagine it imparts something to my cooking. Kids & I did a taste test…oil on right is closer, but I can’t find a replacement for that little jar of excellence that we all agree is superior & I don’t understand what process has made it so.

@nawebb @BlickyIan Along the same lines, I'd love to see a patch that says,
"If it float, flys or *ucks, rent it. It's cheaper."

@chinnychick Been saying this for ages, he changed and reinvented himself (more like selling himself out) to suit her. This rarely ends well, a good friend of mine did exactly the same thing for the sake of a relationship and it went wrong in the worst possible way.

Can’t believe it’s deicing season already. I still have my thunderstorm avoidance season decorations up.
Anyway, why do we deice, what are they using, how effective is it & is it safe?
When ice forms on the wing, it changes the aerodynamic properties. How much? Nobody knows because ice can form differently every time…but that’s kind of the point. We know how much lift we will generate w/ a “clean” wing, but an iced wing is a big question mark. Will it fly? Maybe! But maybe not, and you’d rather not find out it’s the latter when you try to lift off from the runway.
So, we deice the wings, tail & fuselage. If the temperature is warm enough & it’s not snowing or raining, just removing the ice is enough. Sometimes you can do that with just hot air, or hot water. Usually it’s some kind of ethylene glycol, though, with additives. I’ll cover that in a minute.
If there is still precipitation & it’s cold, we need to remove the ice & make sure new ice can’t form…we’re anti-icing (for simplicity, let’s just call it deicing too). Glycol is again used for this purpose, but now we’re adding stuff like thickening agents to make it stick to the wing. Various other additives are present, as well, like orange dye…that helps the deicing truck see what they’ve sprayed & what they haven’t.
There are 4 types of deicing fluid w/ varying differences. The biggest difference is how long the fluid will stick to the jet & prevent new ice from forming. This is called “Holdover Time” and every fluid has changing holdover times based on the weather conditions. Things like temperature & type of precipitation…light snow doesn’t have much impact on the holdover time, but freezing rain has a major impact. In fact, freezing rain can get to the point that your holdover time is essentially zero & there is no point to even trying to go fly.
The FAA publishes new tables of holdover times every year based on tests they run. At my airline, we have an app we use…we enter the time deicing started, the type of fluid used & verify that our flight number & location is correct; the app then pulls the weather (from a very detailed source, things like pressure, wind & exact precipitation rates matter), then spits out what our holdover time is.
If you can’t take off before the holdover ends, you’re out of luck & can go get deiced again, then do it all over. Unfortunately, the kind of weather that calls for this stuff is also affecting the runways & the arrival / departure rates of an airport, so you’re likely to see delays. The runways have their own treatment chemicals which helps prevent the buildup of snow / ice, but that can be overtaken by holdovers, too.
As painful as it is, even just a layer of frost can drive you to deice. That’s not always the case, though; the engineers did the math & identified areas of the wing that frost isn’t a problem. These are often painted in black boxes on the top of the wing…if the frost isn’t all inside the black box, you’re good to go. In part, the cold-soaked fuel – which is stored in the wings – will generate frost when you come down from altitude, even on warm days, and we need to be able to distinguish that from environmental icing.
Now, you might be wondering how we fly through icing if we don’t get deiced in the air. The answer is that once we are flying, the airflow over the wing mostly keeps ice from forming on the wing. It does want to form on the leading edges of the wing, but that shiny leading edge is not painted because the engine is taking hot air from the combustion chamber & pushing it out along that leading edge, keeping ice from forming. The front of the engines have the same…the shiny, unpainted metal bits can get hot when we flip a switch to redirect a little bit of what would have been thrust into the tubes that warm the unpainted bits up.
(Other unpainted bits are heated electrically, like pitot tubes & static ports, which sample the air & tell us speed & altitude)
Damn, out of space…next tweet…

State of our country now where even foreign governments are calling out what’s going on because our own government won’t! 😡

@DaveWallsworth That sim looks awesome! Many many years ago I got to have a go on the BA Concorde Sim at Filton. Obviously the aircraft was out of this world but I remember the sim being run by like BBC Basic computers! Still Kai Tak was fun in it!!

Another two day simulator check complete and licence signed so I can go flying the real thing again 😎
What did we have to deal with this time? Fuel pump problems. Hitting a flock of birds just as we took off leading to a stalling number one engine which recovered then completely failed at around 1000 feet. Numerous departures with engine failures or fires before and after takeoff. Failure of the automatic thrust system. Flying various types of approaches with one engine failed and no autopilot or automatic thrust, some of which resulted in go-arounds and others in landings. Operations in foggy weather including automatic landings and failures of the automatic systems at a very late stage resulting in go-arounds from just 50 feet. Other aircraft avoidance while in the latter stages of approaches in cloud (TCAS system activation). Severe electrical problems including the failure of all four engine-driven generators resulting in the deployment of the Ram Air Turbine to provide emergency electrical supply to essential systems, all while very low on fuel just to add to the time pressure. Arrivals to a busy airport during severe thunderstorm activity and periodic runway closures, again with very low fuel remaining to add pressure to the decision making process. Subsequent landings in extremely turbulent and windy conditions on a flooded runway.
All in all a very busy couple of days during which our teamwork and skills were practiced, assessed and, thankfully, considered good enough to enable our licences to be signed for another six months of flying. While this may sound like a lot to cover and be tested on over a couple of days hopefully it will help those who are nervous of flying understand that our training and checking is to a very high standard precisely because we want and need to make sure flying is as safe as it can possibly be. Certainly after all these years of flying (since 1989) I always take a lot from the high standards to which we are held. Once again thank you to the excellent Senior First Officer I was paired with and both superb instructors/examiners. Now, where is that real aircraft?! 😎

I took my kids to Rome last year because my daughter was studying Roman history.
I’m taking my kids to Athens this year because my son is studying the Greek city states.
I’ll pull my kids for vacation when I want, thanks.
The Principal’s Office@educator4ever36
It’s 2025 and I actually have parents trying to defend pulling their child out of school for a vacation. I get a death. I get granny is turning 100 and lives out of state. But to get a cheaper vacation- nope. Can’t ever support that.

@MartinSLewis Our council is already at it:

Wiltshire spent £230k more of our money than it had to on energy to appear to be “green”. Meanwhile school budgets are squeezed, roads are in a state and services cut. Utter madness!

@BlickyIan They lost our car in that very valet car park a couple of years back. Waiting for them to faff about after long flight was not good for my or my families soul, nor was the devil may care attitude from the staff.
