subhro··on Apollo 8 astronaut William Anders ID'd in WA plane crash
> The response to the vast majority of failures, even stuff as critical as an uncontained engine failure, is not to fast-twitch take some reflexive action, it's to work through a checklist (even memory items are still a checklist) to be sure you're actually taking the right action - and there are tolerances built into both internal and external systems to give pilots time to do that.

Let's see, a pilot flying in the yellow hits turbulence followed by a wind shear, and pulls up...

Something from Davis Intruments or Kestrel would very good. But they are not cheap.

> Flying is a specialized skill, but once you learn it it’s not especially difficult and requires less sustained focus, reflexes and reaction time than driving.

Respectfully disagree (as a 40-something year old aerobatic pilot) with the less sustained focus part, not the specialized skill part.

I like to call it an acquired taste. First you hate it, then you fight it, then you get surprised, finally both you and Perl win.

Perl did not and has not failed. Not even remotely.
subhro··on Working with Tilt/Shift Lenses (2022)
> But comparing older Canon TS-E 24mm f/3.5, or the Samyang/Rokinon 24mm f/3.5 against any decent wide angle lens nowadays is a wash.

Edge sharpness and barrel distortion? ;)

subhro··on Working with Tilt/Shift Lenses (2022)
I am generally pretty fast with lenses that were designed to do manual focus, like Zeiss Otus and Milvus lenses for Canon (For example). Lenses that come with autofocus does not have a long enough throw to be able to perform manual focus quickly and accurately, but it is definitely doable.
subhro··on Working with Tilt/Shift Lenses (2022)
> Tilt-Shift lenses are great and I own one but ... just like many things in photography now-a-days, computation can do much of this.

No it can't. You can not reliably tilt the plane of focus, something that precisely the tilt-shift lens does.

> No, it's not perfect just like an iPhone doesn't take as a good a picture as a high-end Canon/Nikon/Sony.

iPhone actually does very middle of the road pictures. You can never beat a Canon/Nikon/Sony simply because you do not have the sensor size. I am not even going to try to bring metering discussion here.

> And even on a large screen (my 65" TV) they still look great at a glance.

Depends on the viewing distance. Put ink on paper, and then we will talk.

> Let me change the perspective live while I'm taking the picture. IIRC I found apps that do this but they want $10-$20 a month. Here's hoping Apple and Google add it to the default camera apps. This could be even better because given computational photography the phone can take 10-20 shots at 1000fps and then merge them for higher res in the areas where there's less censor pixels per arc angle.

No, you are wrong. When you are shifting, you actually move over the "sensor" in the focus circle, not merely do a cropping gizmo like apps do.

If you want to really understand why view cameras still whip ass and tilt shift lenses are relevant, try taking photograph of a tall building and see how the edges are not parallel and if you try to correct that in software, you will see distortions.

subhro··on The Death of Free Shipping
I dont think you are quite right. To the best of my knowledge, you get 3% back on the Amazon branded cards. If you have prime, then you get 2 more percentage to a total of 5%. So to make up for the difference of $139, the price of prime in terms of cash back, you have to spend $6950 (or ~7000 as the OP said) to break even.

Now if you have Discover or Chase Freedom, they run the 5% quarterly bonus (for the first $1500 spent on the bonus category) at least once a year, so your break even point is even more than what I mentioned earlier (closer to $10K).

ever heard of software bugs and gps jammers? Your second EFB idea is still having a common point of failure, the E.F.B. And being a software engineer, I really do not trust software. :)

subhro··on FAA Aviation Maps
This is a nice website, however there are factual inaccuracies and watered down information. For example, "Visual Flight Rules” (VFR) apply when there is generally good visibility, and features on the ground can be discerned by the pilot." Well, NO. There are speciifc requirements. 14 CFR § 91.155, states (in the worst case scenario) you need 3 statute miles of visibility; 500 feet below, 1000 feet above 1 statute mile horizontal separation from clouds. The previous limits are dependent on the airspace type you are in.

But it is nothing like, yeah, looks about right, so we can fly with VFR. Best case scenario, your wings will be clipped, at least for a while; worst case scenario, you will get a headstone earlier than you should have and your next of kin would be sued for damages.

Because batteries die, stuff overheats and shit hits the fan, sometimes. I always carry backup paper charts even if I am flying with a EFB and a glass cockpit.

I just heard the voice of my instructor in my head. It is NOT a map. It is a chart. :-X
subhro··on Can Microsoft Flight Simulator help me learn to fly or make me a better pilot?
One of the irritating things about simulators (barring FFS) is the amount of lag and lack of feel of air on the controls. MS Flight simulator will probably help you with non flying procedures and communication. Also, it is useful (partially in my books) when doing instrument training.

Otherwise you are better served with a Cessna 1x2 (where x = 5, 7 or if really pushing it 8) and a competent CFI.

Keep the rubber side down.

subhro··on Can Microsoft Flight Simulator help me learn to fly or make me a better pilot?
Sounds very fishy.

> The instructor let me fly for a while then put me "under the hood" so I couldn't see, said "It's my airplane", took control and flipped it all around, and then said "Your plane". The flight controls were all I could see. I could see that I was in a dive with rotation so I cut the throttle, centered the stick and kicked opposite rudder until the rotation stopped then regained level flight.

That is a weird way of explaining what happened and I find it extremely hard to believe this was written by a pilot. I would have never used the word rotation and dive. They mean very different things from what the author is trying to explain. If I was writing this, I would have said, "I was put in a spin and I did blah to recover". Also, there is a very important piece of PARE missing in that commentary, the "P". It is extremely hard, if not impossible to come out of a fully developed "spin", not "rotation", without pulling power even in training aircrafts.

I call this unadulterated bullshit.
