ADIRU in its minimal common form (some vendors might make a beefier one, who knows) provides the equivalent of old pneumatic "air data central" + artificial horizon and turn indicator gyros. GNSS becoming "reasonably easy&quo

LORAN was mostly long range over sea, on the ground we had NDB, DME, VOR, etc all ultimately linking into "airways" for higher altitude operations where earth might be not visible due to cloud cover for example

Except ADIRU isn't INS. The INS unit is separate and often has its own set of gyros and has to be connected as separate input to FMS or other navigational computers, same as connecting GPSes or other radio nav components. For example t

Unreal had a small menu where you could switch between different renderer backends precisely because of things like different cards having different... Driver quality let's say.

It's how you do it in many C++ implementations, but IIRC it's not actually mandated in any way unless you strive for GCC's IA-64 ABI compatibility (the effective standard on Linux for C++) C++'s vtables are also, in my e

Only in certain limited cases, for example, can't have static class instances or anything else that could require calling before a call from "extern C" API. Also now you have to build enough of a C API to expose the features,

INS essentially was expensive and AFAIK once GPS became available started to drop off in use outside of military. And with GPS availability coinciding with switching to more modern integrated Flight Management System/Computer, a lot of

RNAV are less common than people think, and given the limitations appear to mostly be used as secondary help in conditions where one could possibly go by vectoring. Losing them however does drop capacity because now you need extra work to

Mostly EV components - the motors and inverters that drive them can generate a lot of EM noise.

It's possible to deal with it, but one must want to deal with it, plus the "costs" like increased weight, BOM, etc. EV makers don't want to and it's a problem even with the very low bar is consumer equipment

In my experience, that was destroyed under Bush Jr as Reagan-time shenanigans like buildup to Able Archer 83 just weren't widely known. The 1990s still had veneers of legitimate use of force, but the GWOT and especially Iraq quickly e

I haven't before, but due to certain private interests I can explain what they mean by "legacy copper TDM infrastructure". A lot of interconnections between US ATC services were done back with the good old Bell System over th

Modern Standby requires that deepest sleep states take less power than S3 standby, the issue is mainly drivers and applications either waking the system or not putting peripherals into deep enough sleep (or shutting them down entirely if po

A lot of those revelations are due to majority of EFI code other than vendor specific drivers being quite open source unlike the bad old times. Still would like an end to end open source UEFI bootchain, most groups end when they hit the 6

They wouldn't be used for ATC though. Internet access from aircraft is, outside of questions whether it interferes with aircraft operations, outside of FAA purview (at most, it's FCC and ITU-T depending scope)

Can't give real answers without data on Starlink reliability (or non-consumer features), but personally as someone who depended on ATC both as small time pilot and more regularly as passenger, I'd be wary of sat radio as main back

This is not about communications on aircraft itself and will have no impact on aircraft internet. However I'd rather have the backhaul between air traffic control centers done by fiber rather than by Starlink... Not to mention the nake

Being slightly off in adjustment of brakes when landing an airliner results in dead passengers. It's not as visible for manual braking, but that's because the brakes have been "brake by wire" for some time. The scope of

Superset. ANSI/ISO C is not a good language to write a kernel in, because the standards are way more limiting than some people would think - and leaves a lot to implementation. So it's a superset in terms of what's defined

Aircraft brakes are life or death issues that require instant response times to changing conditions, which is why ABS originated in aircraft . The aircraft braking systems are very complex, including active thermal management and automated

Funnily enough, A380, A350, B787, and other new aircraft have their brakes connected by Ethernet (specifically AFDX, a modified variant of Ethernet) so braking actuator signals (and sensor data back) goes as UDP messages. But it makes the s
