Re: Varadero Cuba (you’d think you’re in Canada!)

Because of the US embargo, Cuba can't really draw much from the US in terms of tourism and because of the same embargo procuring the types of goods needed for true luxury resorts/hotels to draw people from further afield can't happen. That leaves Canada and Latin America to draw from. A good portio...

Re: Ethiopian Airlines 737MAX crashes enroute to Nairobi

Very simple final conclusion for Boeing: P.B.S. meaning: Profit Before Safety It was ever thus. Corners were always cut and lives were lost. Why just one actuator on the 737 Classic rudder? Why use easily-pierced aluminium fuel lines in the belly of the 727? Why no full hydraulic boost on the 707 r...

Re: B737MAX Grounded Worldwide

It is actually the other way round. If the aircraft switches the sensors each flight, you have to divide the MBTF by two. Having two sensors, but using only one doubles the failure rate. No. First, MBTF is not affected whether the sensor is used or not, because the signal being read or ignored is i...

What's the difference if it was controlled with FBW or by MCAS changing the trim? MCAS, in its designed role, accomplishes essentially the same thing that a FBW system would. In FBW systems there are no mechanical fallbacks (like the infamous trim wheel in 737). Therefore, any FBW aircraft has to f...
