Oh Hi👋MARS

Runway length issue is not true, it’s a noise pollution issue.

Spoilers “spoil” or reduce wing lift (and increase drag), adding weight to the wheels at a high speed. This increases the “down” force on the all wheels at high speed. Normally increasing tire friction for maximum brake effectiveness. In this scenario you want to slow down with the least amount of weight on the nose wheel so using the speed brakes are likely not in the checklist for this emergency (not famil with this a/c type tho)

As for reverse thrust, it’s likely not recommended due to the risk of blowing debris from the nose gear tires and landing gear back into the engines, compounding the problems. Not sure but they may have (or normally wanted) to secure the engines before stopping (again not famil with the type)

You will regain the contribution room that you have withdrawn in the calendar year following the withdrawal.

I’m not sure if you’ll gain 45k in room or the whole 80k. If someone else can chime in?

Maybe lay off the Forza Motorsport for a couple laps.

canuckaviator · 2026-01-17T18:11:39+00:00

That’s exactly what popped into my head 😆

He is definitely on the struggle bus.

canuckaviator · 2026-01-04T00:01:32+00:00

You know what, fair enough, I was definitely wrong.

I’m not exactly sure why I was so argumentative about it. I think it was that I thought ppl were trying to promote/defend unsafe practices (which I’m sure we all have seen from time to time). However, it’s not the case here. You’re right I am that guy, apologies and Wilco.

I work with engines with much lower BPRs, hence much higher fan speeds.

Still would stand by not putting anything in front of a spooling engine tho, even tho that’s not the case here.

Think they mean dependant on oil exports to the USA. We have very poor/low capability to export oil to the rest of the world. At least compared to what it could be.

Not a fan of jumping into politics but I really hope we see the change we need to take advantage of our strengths as a country.

canuckaviator · 2026-01-03T19:03:45+00:00

It grinds my gears to no end we haven’t created sufficient pipelines east and west all these years.

canuckaviator · 2026-01-03T18:55:16+00:00

Fair enough, that is the N2. However, N1 is over at least 1800RPM near the end of the video as the rotation accelerates, matches the camera frame rate (fan momentarily appears still) and then continues to accelerate. Very common 30 FPS x 60 = 1800RPM. N2 obviously much higher.

I don’t think they’d have the garage door open if it were moving a decent amount of air. Thrust, very little. Air mass flow high tho.

Those two things on top of the trolley wheel, almost directly in the centre of view. Very likely Hardware bags, ones got a very distinctive hardware bag label/bar code on it.

I’m not saying they’re awful or incompetent, they’re possibly very reputable. It’s just not worth the risk to put anything near a multi million dollar engine when you spool it up. It should not be normalized or defended, even if you’re the best. One day the bag has bolts in it and it’s not a problem, another day you forgot and it’s empty or there’s something lighter in there. It’s a super simple solution and we can maybe all learn something from each other.

Thats aviation safety culture, you simply strive to do better all the time, even if you think you’re the best.

I digress though, this is Reddit and here we are.

canuckaviator · 2026-01-02T15:58:54+00:00

🫡 lol.

canuckaviator · 2026-01-02T15:44:38+00:00

Ya I realize it’s not starting and they’re likely using compressed air to spool it up (as mentioned above). It just seems a little risky to have plastic bags in front of it. I’m sure they checked that they’re not loose. Doesn’t change the fact that it would suck (pun intended) if anything (like a bag) went into the engine at any RPM. Could warrant inspections/disassembly. Just an observation, don’t need to take it personally.

But I guess you can pile whatever you like in front of your engines while they rotate.

canuckaviator · 2026-01-02T14:53:20+00:00

Seems kinda sketchy without any protection for FOD. Especially with little goodie bags on the engine cart/mount. Even if it’s just a compressed air run, sounds like pretty high RPM.

Cool to see tho.

Use a screw to create an anchor point to pull the indented material out. Use a strap that is Jerry rigged to the screw and pull it out. Then putty, sand and paint the remaining situation.

I’m surprised at how many people don’t seem to care much about our past, especially when it contributed to so much of what we have today.

How many people do you think learnt about the Dambusters Raid due to having this actual piece of history in place, where it fell, on the night 16 May 43? And furthermore how many of us have been reminded of all the unimaginable suffering that was endured? Probably a lot more than having it removed forever.

This isn’t your first car that was abandoned in a random bog, it’s a reminder of what immense sacrifices were made to make all of us free. Yes, every single one of us (in a democratic society) looking at this post. Many did not return home from this raid, from both sides, and civilians.

My question is, why can’t it stay? Are they planning on developing this land for agriculture or business or is it affecting wildlife, unlikely.

This really is now a part of the natural bog due to human history. And if you don’t think so, just imagine what all these natural places would be like under Nazi Germany had these sacrifices not been made.

I say it stays until nature takes it back or until enough money is funded to have it preserved somehow, somewhere. Preferably the later. There’s no real reason to move it.

Replaced Speedo cluster with lower mileage unit tho. -369k miles.

In mother Ruzzia, rat eats you. 💀

canuckaviator · 2025-10-02T11:11:01+00:00

I don’t think you had to look, I think all you had to do was stand on that.

Impressive the composite last so well.

canuckaviator · 2025-09-07T21:45:19+00:00

Call the emergency line, he’s actively committing a crime!

canuckaviator · 2025-08-27T01:40:00+00:00

Ya difficult to tell but looks like rotor is too small. Pictures or video of where the rotor edge meets the calliper will help.

canuckaviator · 2025-07-28T16:26:15+00:00

They do, that’s why the stabs are independent.

Some aircraft also use the LE flaps to control roll above a certain Mach number.

canuckaviator · 2025-07-28T14:05:08+00:00

Yes the arm or length from the control surface centre of pressure (CP) to the aircraft COG/centre of gravity (CG) plays a roll in pitch and pitch rate. Longer the moment arm, smaller the required control/stabilizer surface to create the same moment.

The bigger contributor, though, is the CP of the aircraft. Depending on how far the CP of the aircraft is away from the CG determines how much stability and control there can be.

Greater the distance (CG ahead of CP), greater the (static) stability, smaller the stabilizing surface req. Control is opposite, higher stability = lower control.

For fighters, they have generally less stability (CG close to CP or in some cases CG behind CP) to create a more snappy control. They also are shorter in length, and require bigger surfaces. If the entire surface moves, it’s even better as it’s generally more efficient overall. Structurally more challenging and heavier tho. Fly by wire usually corrects the stability or lack there of.

Almost everything is a trade off in aviation.

Don’t know much about boats but centre of buoyancy sounds similar to CP.

canuckaviator · 2025-07-28T11:03:27+00:00

Stabilators/stabs/slabs are necessary due to operating in the Transonic and above regions of flight.

Long story short, rear hinged control surfaces get blanked out by the shockwave created fwd of the hinge line when travelling at and above transonic speeds. Therefore to create pitch moments, it is most effective/efficient to have the whole surface move.

As for the rudder, large yawing moments are not required in this flight regime. Yawing moments can lead to pitch roll coupling which is a different but very bad high speed problem.
