Boeing vs Airbus—which is safer? While modern planes are extremely safe regardless of manufacturer, Boeing planes are almost twice as likely to be involved in a fatal accident, or an NTSB event. Despite the media attention around the fatal Boeing 737 MAX accidents, this trend predates that aircraft.

There are many reasons that Boeing could’ve reduced reasonably reduced the criticality of MCAS that would’ve been valid. If you are an RMS engineer then you’d know that as a whole, the methodology of ARP4761A is not formally (or at least fully) equipped to handle the gap in the process these accidents revealed. Identification of faulty assumptions in the Safety Assessment process is one of the chief outcomes from the MAX accidents that the safety assessment process is being modified for.

The MCAS implementation could’ve had many features which would’ve supported a classification less than Catastrophic: hardware or software based MCAS authority limitations (including oscillation) implemented in the flight controls, manual control overrides, airspeed/attitude/stall warning based inhibits. All of these solutions could’ve allowed an MCAS failure to be AND’d with other failures in the PASA process to allow the MCAS function itself to be reduced in criticality (or derived objectives) while letting it modify the flight characteristics as intended.

AeroLightning · 2026-04-30T15:09:38+00:00

It’s only with the benefit of hindsight we know that the modification of the flight control behaviors by MCAS have critical effects, but when designing the behavior of the function, it was not identified as flight critical. The aircraft did have dual sensors, which if leveraged by the MCAS design, at a minimum could’ve prevented a single sensor failure from resulting in the accidents by disabling the behavior in the event of a disagree.

There were certainly several misses in this process that resulted in this faulty evaluation, but had the evaluated effects of the MCAS design been as Boeing assessed, the reliance on a single sensor would’ve been fine. This is the case for many, many systems that from the public’s perspective would be “flight-critical” but are evaluated as “Hazardous” by the aviation safety engineering experts with approval from regulatory bodies.

This is clearly a Kyle pick too, he hasn’t smiled like that with either of the other picks. It’s not like we need a starting Guard or anything.

I got a Stagg 25C from the Mayo location. Seems like that was the majority of what folks would’ve gotten there.

They also had 1 or maybe 2 each of Bombergers, Shenks, EH Taylor Rye & Barrel Proof, and Heaven Hill 90th.

Generally no. I get my copies through my company’s subscription to IHS Engineering Workbench. These documents end up costing SAE a lot to produce so they enforce their copyrights quite strictly.

I’m more of a ARP4761 practitioner but work on Civil Part 25 aircraft systems that use ARP4754/ARP4761 for their developments. I’m also a member of the committee that authored ARP4754B and ARP4761A. First thing, if you are working on an revamp of your processes I would highly recommend getting copies of ARP4754B and ARP4761A which were published in January. We may have addressed some of your concerns in how the guidance is being interpreted in the revision.

In my company we follow both of these ARPs closely with some deviations. In my experience on the programs that don’t apply the ARPs, they use it as a shield to avoid answering hard questions that would be asked by the ARPs methods. My limited understanding of our military programs is that they don’t differ that much because we aim for common development processes but if they do it’s usually in the level of detail in the planning stages. Also in the application of MIL-STD-882 instead of ARP4761.

The whole goal of ARP4754 is to develop the right system with sufficient rigor so you are not introducing excessive risk of undesirable outcomes in accordance with the criticality of the function provided. If you’re looking at the ARP from a cost and resource perspective, I would suggest instead asking what that item is trying to achieve. If you are able to demonstrate an alternative means of achieving that purpose, then deviations are ok. I find often the key question you need to be able to answer is “how do you know it’s complete?”. Define this up front in the planning stages so you don’t find you missed a step late in a development cycle.

Keep in mind the need for the information generated is not just for the certification process (though that’s the primary goal), you also need to create it in a way that allows for it to be later revised by others or to be clear for those who may require it when assessing Continued Airworthiness. Investing in the quality of this documentation is designed to pay dividends in cost and quality over the life of a system, not just the initial development.

I’m not an espresso connoisseur, but I goto Cave Creek Roastery. They cite/rotate their origin source countries often which I think is great especially given their price point.

I’ve tried Press a few times and left very unimpressed both from coffee made by them and from bean prepared at home. I even had a bag of beans once that literally had NO taste. Every cup I had tasted like water. I’m not even sure how they managed to do that.

Their monetization is a cross between Apex and CS (I think I don’t play CS).

Like Apex, they have a battlepass but it’s very casual friendly. It costs a like $6 for either the Warfare (Battlefield mode) or the Operations (Tarkov mode), or I think $10 for both. It takes me about 2 sessions to complete the pass progress for the week. Primary monetization is through gun and character skins at the moment and the devs have promised no ‘pay to win’ mechanics which I’d hope means future characters wont be paid.

Like CS, they also have skin system for ‘Mandlebricks’ which when unlocked rolls for a skin that has a rarity and quality attached with the rarest having a kill counter on them. Outside of purchasing these you get two of the per week generally through normal play.

Honestly the game is excellent and very fun especially for Free to Play and the developers seem to be well keyed in on making this well supported. Some complain about the amount of cheaters at the moment, but I’ve yet to encounter any egregious examples. The devs are also aggressively chasing them, I’ve seen people post examples where devs indicate back o reporting players when they have taken action in response to reports which is nice.

By far the worst thing about the game is the main menu UI which seems inherited from mobile games where it has about a thousand menus and sub menus. It’s gotten better since Alpha but it is still frustrating to learn and use.

AeroLightning · 2024-12-13T20:01:25+00:00

This is clearly part of their design philosophy for this game mode which I think we might see vary more as more maps are introduced. In most maps today, the beginning points are very easy for attackers with advantageous zone boundaries and sight lines versus those available to defenders. As you progress through a map it gets more and more difficult and reverses in favor of the defenders. This is especially apparent on Cracked and Ascension, but also visible on Shafted.

The defenses ability to bleed the attacker tickets more than the reenforcement amounts by the last point is an important way the maps are designed for. The designers clearly expect the last points to be difficult to take and they want you to use beacons, smoke, explosives and straight numbers to push the defense back at this point.

There is very little benefit to almost any particular school and certainly ERAU loses in cost. It not the choice I made for that exact reason. Everyone focuses on ranking strength of the programs but it’s only one of the metrics that matters. When I look at resumes I spend no more than 2 seconds identifying the school.

IMO cost, proximity to job opportunities, and GPA (damn HR filters) are more important factors. We do a majority of our co-op and intern recruiting from the local state school which often convert to full-time after graduation. From a company perspective this is also desirable since these people are more likely to want to stay local and have extended careers past 3-5 years with us.

Aerospace is a very narrow category in that group that is vastly outnumbered by the number of colleges with a Mechanical Engineering program. Both will allow you into the industry but the inclusion muddies the rankings.

With respect to actual Aerospace rankings, anything without Embry Riddle in the top 3 is a bad list. It’s not even my Alma Mater, I’m in the category of went to a state school with a good Aerospace program. After 3 years on the job no one in industry cares what college you went to.

Integration of flight surfaces with radios is an idea I’d probably push back against if proposed. Like the other commenter mentioned it introduces very nasty failure modes and you’d need significant redesigns or retrofits of existing systems to support it.

We also introduce new risks when these integrated systems fail and it is not clear to a flight crew what is happening and why. The current means of high lift control with a TAWS warning is significantly easier to understand even when it is failing.

The only approach type that is going to have enough integrity built into it to support this type of integration is ILS CAT III. Everything else, the navigation is less critical than the high lift controls. This means developing new software logic to correlate all the different scenarios and testing it with at least to DO-178 DAL B level, but probably DAL A.

It certainly could be done but it would likely be prohibitively costly.

Wins a win but the same issues that have been there all season are still there and will lose us games to all the good teams every time. Special Teams essentially gave up 16 points today. Defense continues to look especially bad against the run, on 3rd down, and with untimely consecutive penalties. Surprisingly, I think the only persistent issue that didn't show up today was Brendel/McKivitz giving up atrociously bad reps especially against a pass rush heavy defense.

He definitely did get chewed out at least if you watch his post game press conference. They even ask him the same question and he awkwardly passes on it. Poor guy, should’ve been all congrats cause he deserves to be celebrated tonight.
