Re: A350 flight control airworthiness directive

This seems like that some allowed dispatch conditions on the MMEL combined with a software design issue were on the verge of a single or probable fault to achieve a complete loss of control scenario.

Re: DL A220 rough landing, near-tailstrike at MSP

99% of you missed the sudden and deliberate pitch down at 20 ft causing the “firm” landing…never in my 30 years of airline flying would I have or ever done that in a transport category aircraft. Remember the A380 at Oshkosh pushed then tried to catch it…broke a body gear and it did not fly for 2 da...

Re: Russian Airbus and Boeing aircraft and sanctions

I believe that the expectation to see the MC-21 in the west is now gone. And if they have western suppliers, this is now gone as well.

Re: Embraer E2 Production and News Thread - 2022

The engines have significantly lower fuel burn. From what I heard, that’s only on paper. If it was that simple to create the E2 scope compliant, I believe that Embraer would have done it already. And I heard from people from MITAC that the E1 was unbeatable under current scope. And I believe that t...

Re: Embraer E2 Production and News Thread - 2022

Beating current E1 (new wing tip version) economics under current scope is very hard. The M100 would not be able to match it and neither would a smaller version of the E175 E2. Maybe only for maintenance costs. But not fuel burn. Unless significant changes in new materials, which is very expensive i...

Re: Embraer E2 Production and News Thread - 2022

“ With the launch of the 70 to 90 seater turboprop expected later this year or early 2023, Embraer is developing a new aircraft that would easily eat into the E175-E2’s market. Vice President of Marketing and Product Development, Rodrigo Silva e Souza, told AirInsight in August ast year that these a...

Re: Boeing 737 Max Netflix documentary- Downfall

I was really shocked by this reaction time limit as well, without any training being required. And the language used in the internal memos is unbelievable.

Re: Embraer E2 Production and News Thread - 2022

Yes, the new TP which might be announced in the end of this year. I believe that they shifted focus.

Re: Airbus A220 Sales Campaign Thread - 2022

I’m not really seeing Lack of cockpit commonality as a problem for the 220. Airbus is still very able to package it with the 321 for a winning combo and has done that a couple of times now. Will it improve marketability? Yes but I don’t think it’s worth the investment till the 220 is NEOd and the 3...

Re: Emirates serious incident on takeoff on EK231 DXB-IAD on 20 December 2021

Quick question. Hope someone will answer before our ever-vigilant admins delete (queue GASP!) criticism of Boeing. What kind of an engineer would design a flight director that allows setting take-off power with altitude on zero? No dings? No warnings? Seriously? Again some invisible abbreviation in...

Re: FAA to prohibit many flight operations due to risk of ‘5G’ wireless interference

Aviation has become very sensitive to safety concerns. To reach the required Design Assurance Levels for safe critical systems is very tough. See for example the concerns regarding design errors on modern microprocessors, which requires current Fly-by-Wire architectures to implement triple dissimila...

Re: FAA to prohibit many flight operations due to risk of ‘5G’ wireless interference

So the radios in the aircraft have poor filtering and need to be upgraded is what I took from this thread. It isnt like the aviation industry had years to prepare for day or something. What kind of design has that kind of variance? +-200Mhz? To me that screams poor design because at the time the co...

Re: Altimeters, static pressure, and lift

I had an interesting thought earlier today. We know that when the air is accelerated, the pressure decreases, which is why the airfoil causes the airplane to lift up (in combination with pressure under the airfoil being relatively changed/high). We also know that altimeters in-flight only read the ...

Re: FAA to prohibit many flight operations due to risk of ‘5G’ wireless interference

It seems the only 2 viable solutions to ensure safety is to: 2. create transmitter-free zones beneath instrument approach path corridors (1nm wide x 5nm etc..) e.g., what Canada is doing, to avoid the potential risks of bogus RA' readouts. I guess right now it's just a good old standoff between the...

Re: FAA to prohibit many flight operations due to risk of ‘5G’ wireless interference

There is no issue for someone using the 5G cellphones inside the airplane. The issue is the airplane flying over 5G towers. Some airports have cellphone towers very close to runways final approach paths. This could be an issue to some radar altimeters if the tower is transmitting the 5G C-Band and ...

Re: FAA to prohibit many flight operations due to risk of ‘5G’ wireless interference

Is the UK 5G Implementation any different to what Verizon, for example, plans in the US? Why don't we have the same issues in the UK also? I think the UK stop their mid frequency 5G allocation at 3.8GHz, with aircraft radar altimeters operating in the 4.2–4.4 GHz range. US frequency allocation if d...

Re: A330 FMCG Update with Honeywell navDB

Your aircraft does not allow any flash drive upload?

Re: GLS Approaches Published by FAA in KSFO

GLS will only pick up when multi band GPS satellites are available and allow CAT2 and CAT3 approaches. When this happens, it will replace ILSes very fast. Currently, there is not much demand due to CAT1 only constraints for GBAS, and LPV is cheaper and easier for the areas where SBAS coverage are a...

Re: Modern single aisle aircraft specs & comparisons, scores; Flies NB Scrapbook©

Great for the explanation. Seems solid for me.

Re: Do manufacturers/airlines "update" the flight computer systems

They update avionics and flight controls software a lot. I would assume that a new update comes almost every year for a new platform. Older platforms can take a little bit longer, but are still updated once in a while. Updates usually are intended to fix known issues and also to introduce new featur...

Re: Modern single aisle aircraft specs & comparisons, scores; Flies NB Scrapbook©

But I believe Azul has their aircraft configured to 137 seats. Therefore, 132 seems a little bit low for a high density. KLM has 132 in dual class cabin.
