Scared of flying in an Airbus A220

Multiple airlines grounded their entire A220 fleet amid engine concerns Paradoxically, this should make you feel safer, not less safe. The A220 has had zero accidents. Grounding it is not a sign that ...

Why don't Airbus planes have perfectly smooth front sections?

It is not about Boeing versus Airbus, but rather about old versus new. Your representative image for Airbus is an A320, whose technological competitor by Boeing is the 777. Juxtaposing the two, we ...

Why did Airbus mix "colored light means ON" and "colored light means OFF" in the overhead panel?

The logic for illumination of buttons on the overhead panel is called the dark cockpit concept, previously also called the Forward-Facing Crew Cockpit. It was originally developed by Airbus for the ...

Why do Belugas keep executing a go-around?

I wasn't on the flight deck, nor do I have inside information, so this answer is an educated guess. I assume this is flight-training for new Beluga crews and/or license re-validation which is included ...

Why don't Airbus planes have perfectly smooth front sections?

The pinched-nose airplane has its (flat) frontmost windshield panels almost touching and raked back, which forces the vertical crease. The corresponding panels on the other airplane are farther apart, ...

Scared of flying in an Airbus A220

How will you be getting to the airport? Flying in an airliner with a relatively poor safety record is still orders of magnitude safer than traveling by car, for example. – Frog Driving in a car – ...

Why did Airbus mix "colored light means ON" and "colored light means OFF" in the overhead panel?

Scared of flying in an Airbus A220

If the FAA issued and AD, and the airplane is continuing to fly at this point, that means that the operator is in compliance with the corrective fix listed in the AD. As to your safety on that flight,...

Does Boeing and Airbus perform extensive safety inspections and/or stress tests on each other's aircrafts?

No. What advantage could they possibly hope to gain by doing so? Everything there is to know about commercial airliners is available in excruciating detail, submitted to FAA and EASA in millions of ...

Why cant all planes use the best engines like the GeNX or the Trent XWB?

Why doesn't Airbus certify airplanes with the best engine in the market? For example, the A330 had a General Electric CF6-80E1 engine which was very small for it Because when the A330 was first ...

Why don't Airbus planes have perfectly smooth front sections?

I think you're comparing a 787 in to top to an A319 in the bottom. The 787 is unusually smooth in that area. It is a composite airframe, which allows some additional freedom to use curvature. You ...

What happens if you preselect your destination QNH during cruise?

Mode-C transponder reporting is done using QNE barometer settings, regardless of the QNH setting by the pilot. This precisely avoids the problem that you mention. The goal of the transponder is to ...

How reliable is the Airbus FAC calculated gross-weight?

This is old FMS. GWFK is AOA/FAC calculated, and used for Vls when landing. The GW in the lower ECAM is based on the figures you put in the FMS (fuel+ZFW). I believe the newer FMS gets Vls based on ...

On the A321neo, what determines the 'time to land' when an Additional Center Tank System Fault is triggered?

The reason for that flight time is due to the CG limitations. I don't have data from the 3 ACTs, but I found this revision of the AFM document of the A321 with 2 ACTs from FAA regarding this (link). ...
