Re: FAs Disarming Doors Before Gate Arrival?

I believe KLM were the first to do it. It's certainly helped easyJet dramatically reduce the number of inadvertent slide deployments. It's part of a wider procedure designed by a human factors expert. Disarming after the seatbelt sign is off is too late, and the call coming from the cabin crew defea...

Re: Titan Airways fleet change?

I believe the jet2 "geriatric fleet" (around 29-30 year old aircraft) is about to get much smaller. Many of the oldest are cycles limited and will be leaving the fleet very soon. It's not worth paying to extend the life of these older ladies. So I imagine the same applies to Titan.

Re: About APU start up / Shut down

I knew about the 4 engine airbus', but I'm still surprised about taxying on 1 generator on the 330. It's quite rare in aviation to have no redundancy. But the A320 is well known for its electrical transients.

Re: About APU start up / Shut down

The APU is required for engine start, even if a GPU is connected. The GPU doesn't provide any air pressure to start the engines. The norm for most big airlines and major types is to start engines during pushback using APU bleed air. Also, to disagree slightly with someone above. The APU is normally ...

Singapore airlines were guilty of this back in the 90s. They would turn up at LHR requesting "fuel priority". Of course no such thing exists, and the airline found themselves in trouble for it. It's just bad planning.

Re: Impact of 1.5ton of moving cargo on A320.

It depends on what the centre of gravity is for any given flight. If the aircraft already had a rearward C of G, and then some baggage shifted rearward, you could end up out of limits. Typically an A320s payload could be around 15 tonnes. So if a full 1.5 tonnes moved, I think you could say it's a s...

Re: Which runways warrant airbus MAX braking setting

Although, if it is a really short runway you can use maximum manual braking for any landing distance calculations. But in decent conditions auto brakes MED, max reverse and flaps full is usually good enough even for a 1600m runway in an A319/320

It's not dependent on the age of the airframe. It depends on what ELAC (elevator aeileron computer) standard the aircraft has. Many airlines have by now upgraded their fleet to the ELAC97 standard. This does make the aeilerons act like the spoilers on touchdown. As for crosswinds, they do the same t...
