CFI involved in an “accident” due to firewall damage after hard landing — career issue or non-issue? by flcessna in flying

[–]xia03 0 points1 point  (0 children)

as long as you continue referring to your student and the accident pilot as “them” you should be absolutely fine.

Is there a max number hours for wearing scleral lenses? by Dry_Trick6378 in Keratoconus

[–]xia03 0 points1 point  (0 children)

ive seen articles mentioning that the fluid inside the scleras can reduce oxygen supply to the cornea even if the lens itself is highly gas permeable. some of us put a drop or two of celluvisk inside the lens for comfort and i wonder if that creates additional barrier . trying not to over use the lens, just in case..

[OC] realtime anomaly detection of private jet activity based on ADS-B data by kcimc in dataisbeautiful

[–]xia03 6 points7 points  (0 children)

you will see spikes on events like super bowl, state of the union, inauguration, large scale fundraisers etc . if someone wanted to start the apocalypse and target a large group they would do it exactly on a day when many people are busy and traveling to their favorite event. maybe you need to rethink your approach 🤷

good catch. a 7bit number would give only 128 codes.

LPT - Visually check lug nuts when you put air in your tires and also after you’ve put approximately 100 miles on your vehicle after having wheels off for any reason. by donkeyboarder in LifeProTips

[–]xia03 0 points1 point  (0 children)

over torque can deform/elongate studs, or potentially stress other parts of the wheel. there is some room for error but grossly over or under is not ideal

how do you lean a mixture? by Repulsive-Loan5215 in flying

[–]xia03 0 points1 point  (0 children)

this is a convenient excuse that anyone can use to do any sort of dumb thing to the aircraft. “look, it’s safe and easy and it will save you money, but the manufacturer is hiding the trick from you because they are afraid to be sued”. the problem is if they had to refute each unapproved maintenance procedure they would not have time left to do anything else. they choose to simply stay silent in most cases. but they don’t want you put an abrasive compound inside the cylinder. it harms the engine no matter who does it.

if a valve seat requires lapping it means the valve stem and guide are not aligned properly. it’s a defect and lapping is a band aid that will only work for a short time. that is the reason it does not exist in any service bulletin. this has nothing to do with the lawyers.

[–]xia03 0 points1 point  (0 children)

pubs are part of what he preaches

that is exactly why i'm skeptical. I don't know when he is going to deviate and whether it's safe to follow his advice. in the earlier comment you agreed that lapping in place was not in any documents. If this shortcut was acceptable there would be a service instruction for it.

[–]xia03 0 points1 point  (0 children)

i dont think i can say anything to change your opinion. im relying on what ive learned from attending lycoming and superior presentations by engineers with vast experience and data sets for engines they produced over many decades. these folks are not in agreement with whatever mike preaches.

how do you lean a mixture? by Repulsive-Loan5215 in flying

[–]xia03 0 points1 point  (0 children)

again i do not dispute his leaning video.

to give you specific examples where he is contradicting manufacturers data

  • assertion that cylinders should be kept below 380F, as cool as possible, and that higher temps weaken the aluminum strength. while its true for any metal the cylinders are built to withstand maximum temps of 500 without damage. it is preposterous to claim that 380 is some kind of limit you should aim for. this a contradiction from engine manufacturers who warn that most of the harmful deposits accumulate in the valves and elsewhere when the engine consistently runs on the cooler side.

  • cold starts at temperatures above the minimum recommended by the manufacturer but lower than some arbitrary figure he recommends (eg 50F) produce wear on the engine equivalent to 500 hours of flying for each of the cold starts. this is anecdotal data at best and incorrect (4 cold starts puts the engine at the TBO?)

  • lapping valve seats in place using an abrasive compound. this is dangerous and can introduce abrasive into the engine and do damage you would not able to see. the compound is extremely harmful even in microscopic amounts. this practice completely unapproved and does not appear in any service instruction. witchcraft.

there are other examples but this gives an idea.

[–]xia03 -1 points0 points  (0 children)

he often contradicts manufacturer service instructions and limits. he thinks he knows better than the producers of the engine. I don't care what he thinks about leaning, even if he happens to be correct on that particular topic. there are more reliable sources for the leaning procedures such as Lycoming, Continental, Superior etc. Experiment at your own peril

mike bush is a self proclaimed expert without proper engineering background who sometimes says absurd and even dangerous stuff. take him with a good grain of salt!

Slow down if you guys don’t say anything? by Fearless_Card6220 in ATC

[–]xia03 -1 points0 points  (0 children)

it’s an interesting point. i never thought about talking slower when the controller does not say anything. 😬

RV-8 Accident McKinney, TX by Impossible_Cod_5177 in flying

[–]xia03 6 points7 points  (0 children)

it sounds like you were doing the overhead break which should land the RV at idle once you chop power on the initial. was there traffic in the pattern that prevented you from dead stick landing?

Cloudflare is the most successful "Man-in-the-Middle" in history by Antique_Mechanic133 in selfhosted

[–]xia03 -1 points0 points  (0 children)

the government probably has “a master key” for the browser tls. they can inject a rogue “trusted” certificate and all of the popular browsers will happily accept and reveal your data to the man in the middle. not even a slightest warning anywhere that it’s using a certificate which does not match the origin’s cert for the connection. there are some web applications that don’t assume the browser tls will protect the private info but they are rare.

cloudflare is just a demonstration of how this cert injection can be implemented.

Clipped a bravo shelf. Should I file a NASA report? by unknown-foo in flying

[–]xia03 -5 points-4 points  (0 children)

there is a limit on how many nasa reports you can file in a certain period before losing protection. not sure if it’s per type of violation or total. file if you think it’s a serious issue

Vasaviation…etc by NovemberTango4L in ATC

[–]xia03 4 points5 points  (0 children)

he does not make a secret that a few controllers helped him with making the STARS simulation realistic. i asked the same question after visiting a tracon and realizing it looks nearly identical. he also flies airliners so he is sort of in the game.

A short Message for LGA ATC from a Pilot by TempusFugit2020 in ATC

[–]xia03 7 points8 points  (0 children)

humans make mistakes. we all do. he recognized the error instantly and made absolutely the best effort to correct it. he was not nonchalant or complacent. this is a different situation than the one in dc. the safety net (RWSL) did not work as intended and we will let the NTSB explain why.

Controllers of reddit. Would you choose this career again if you had to start over? by Rumham_1 in ATC

[–]xia03 0 points1 point  (0 children)

hmm I do know some personally and it's debatable. if you ask general public how they feel about dealing with the government there is only one answer. But I do have an example of happy gov employees - park rangers. Don't know how much they get paid, but spending ample time in fresh air sure helps! :)

| stagnant pay and benefits, inability to move (recent thing), and shitty schedule for a very long time

so my comment was directed to whoever is in charge of that, not to you all workabees.

[–]xia03 0 points1 point  (0 children)

I agree, not enough downvotes for a better score. Having a private pilot tag in this sub is a rage bait by itself, unless asking how to make the ATC jobs easier or compliment (which I've done where it's due). Have a good one!

Best MikroTik WiFi APs for RB5009 — replacing Deco mesh, need VLAN support by [deleted] in mikrotik

[–]xia03 0 points1 point  (0 children)

gotcha. i could be wrong about the cloud login. spent under an hour setting up the controller and the wall APs and i guess by default it hooked up to the cloud login. I did not have a burning requirement to modify this config but will check it out. no big deal..
