Re: First New-Build ATR-72 Freighter Takes Flight

Compared with other turborpops, the ATR has a relatively thin wing. Not surprising, its designers came from Concorde, at de Havilland from the Beaver and Otter. The original ATR boots had to be modified (extended). The design was fully compliant with the applicable airworthiness requirements, which ...

Yes.

I think it was rather common in the 20s and 30s. Low alitude flying and flat fuselage undersides helped.

Re: Another Passenger Opens Emergency Exit

The locks are electronically powered and automatically set by throttle position iirc. The plane in the video was parked, the locks would automatically be deactivated so that the exits could be used in a real emergency. The crew doesn’t press a button to lock/unlock the exits. Nope. It won't be acce...

Re: What made Airbus make the a300 as a twinjet, and why couldnt McDonnell Douglas do the same with the DC-10?

Why should that not be focused on? Governments provided the money to develop the airliner and provided the early customers to get the production line up and running. Without early customers you don't survive to get later customers. Once the startup costs are paid off you can offer great deals like ...

Re: Rolls Royce loses £5.4bn, closing two factories, looking to sell assets

Rolls-Royce will likely survive. Like Boeing will. Too big, too important to fail. It is interesting to note the civil engine type certificates have been quietly transferred to Germany, the type certificate holder in Rolls-Royce Deutschland. Derby is now only a subcontracting site. This is probably ...

Re: What made Airbus make the a300 as a twinjet, and why couldnt McDonnell Douglas do the same with the DC-10?

A300 went ahead because their governments wanted to be in the airliner business. There's no way MD or any for-profit entity would have invested in A300 as it was at launch time. It did not have enough payload/range to be useful except for short hops. It largely sold to airlines owned by the same go...

Re: Current status Fokker F-28-1000 fleet / TU-TGW

The response is on on the EASA web site, which provides current type certificate data sheets.

The Fokker 28-1000 TC is still valid. This TC also carries the Fokker 70 and 100, derivatives of the 28.

Re: Why are Air Canada’s A220S flying below 30,000 ft?

An untimely IFSD can be also potentially catastrophic. No it's should not. The airworthiness design (Part 25) and the operationnal (Part 121) rules are written to prevent such outcome. Some engine failure modes such as uncontained disk failure can be catastrophic, but this is not involved here.

Per design, an IFSD is a minor event. It is nevertheless undesirable due to associated operationnal consequences (drift down, diversion) hence the controlling measures implemented to control it, restricting the flight enveloppe to minimise the risk of occurence. MCAS untimely activation is demonstra...

We'll need single pilot ops to have a chance for that market to ever return en masse.


Autonomous or semi autonomous operations might solve the flight crew issue. Lower cost, lower mass. Better safety possibly - if properly done.

It is true that aviation in isolation will not sustain the required R&D in hydrogen, the first enabler being to produce 'green' hydrogen.
