Re: Flight attendant jumpseat

Where I work (EASA), we can’t give spare FA seats to full-fare paying passengers, but we may use them for staff travellers (even those that do not work for an airline) - so it’s a matter of Company policy, rather than Safety.

No…

Re: Do you use less fuel by using more runway?

Actually, reduced thrust uses slightly more fuel, than full T/O thrust. The increased fuel cost is, however, more than completely offset by maintenance savings.

Re: Why APU after taxiing in narrow bodies?

We actually do NO APU taxi-in, both on narrow-, as well as on wide-bodies at our home base. Most of the time it works pretty well - the ground staff is aware and waiting with ground power. As others mentioned, the main advantage is saving an APU start cycle, not fuel. What I can’t understand is low ...

Re: Which under rated aircraft did you really enjoy flying

Never flown the 1900, but I was told by many colleagues, that it flew much better than it looked.

Cessna Caravan - not the sexiest airplane out there, but It flew beautifully.

Re: Update: China Airlines orders 787 for fleet replacement of A330

Does Boeing offer lower weight variants like Airbus. Seems a "high "weight variant like a 789 gets you into A359 territory. Yup, in fact you as an operator can always specify a lower MTOW of your liking. ANA flies Domestic 787-9's at a lower 226t MTOW, and Domestic 787-8's at 202t MTOW. P...

Re: Flaps and aborted landings/go-arounds

Not super cruicial, especially on all engines operating, but forgetting them may cause any of the following: - reduced climb rate (normally not a problem on all engine) - easy to exceed flap placard speed - may trigger landing gear warning (like in the recent AF 777 incident) So not retracting them ...

Re: Fuel Planning Questions

EASA in their regulations always says “expected routing”. So the operator may plan any route / profile they think is most likely to happen. Technically you don’t even have to plan fuel for the entire SID/STAR (although most operators do) - if, eg. you know that most flights don’t fly the entire proc...

Re: 737 Bounced landing and then go around -serious incident?

As per Boeing lingo, anything below MDH/DH till touchdown is a “rejected landing” and after touchdown it’s a “balked landing” :geek: They differentiate it, because in Boeings TOGA button does not work after t/d, so the technique for doing it is slightly different. Nevertheless, as others mentioned, ...

Re: Fuel consumption-Climbing versus Cruising

Climb - approximately 2.3-3 times higher fuel consumption per hour than cruise Descent at idle - about 3-4 times less less fuel consumption than cruise. It’s not totally comparable in terms of fuel consumption per distance flown, because during climbs and descent true air speed varies quite signific...

Re: Norse Atlantic Airways News and Discussion Thread

According to Norse on Twitter it was "near full" Initial FL 380 means TOW of approximately 200 tons. For a short-ish flight like OSL-JFK that would mean payload of approximately 30 tons or ~300 Pax Thank you for the calculation. 300 PAX is a good load factor of 87% The Dreamliner arrived ...

Re: Norse Atlantic Airways News and Discussion Thread

Anyone know the load? It went straight to 38000 feet. I know the 787 is very capable and the 4100 nautical mile distance is no problem for the plane. Still impressive to see. According to Norse on Twitter it was "near full" Initial FL 380 means TOW of approximately 200 tons. For a short-i...

Re: airplane gliding

Re: airplane gliding

At what speed ? In what configuration? Sounds like something I should try if I have some spare time in the sim ;) If I remember correctly, last time I tried it, we intercepted the G/S in clean configuration and at UP/Gdot speed and the plane happily flew the profile at constant speed. Then at ~5-6 ...

Re: airplane gliding

I'll add that the glide ratio of an airliner is way better than a Cessna 172. More like 1:15-20. For every 10000 feet, you can expect to glide 30 nautical miles at best glide speed. Plenty of time to try to restart the engines and look for landing options. Oh for sure, gliding characteristics of mo...

Re: Understanding Emergency Descent Altitudes

I have too wondered how this profile is construed - reaching FL140 within the time oxygen generators are working and continuing on FL140 for 30 minutes without oxygen is quite understandable. What I don’t quite understand are these intermediate stops for a few minutes (FL290 and FL250 in the example...

Re: Curious: BA Takeoff Procedures - Gear Retraction

Related question: to what extent does deceleration rate affect brake heating? Doesn't the same amount of energy need to get dissipated either way? The only thing I can think of that would make a big difference is using more TR or spoilers on a longer runway and thus having to do less braking. The d...

Re: AF 011 go around - Possible flight control issue

Yup. It happens quite often to get the siren blaring at you when you extended the final landing flap too quickly, while the gear is still in transit. Quote annoying IMO…. The same goes for go-around when the gear is selected up with flaps still in landing position. How very odd, your not busy enoug...

Re: AF 011 go around - Possible flight control issue

Re: Do some jetliners need to level off after takeoff climb to build speed for flap retraction?

Never flown a quad - but modern twins climb quite happily during acceleration/flap retraction on both engines - even when heavy and with reduced climb thrust. OTOH acceleration on single engine does require level (or nearly level) flight. P.S. the closest to level acceleration was when I flew ATRs i...

I fly over Greenland all the time and this question pops up every now and then, and gets some people quite vexed… Here’s my take on it, in addition to what others said: - ETOPS and terrain escape are two completely separate scenarios.

Re: Layovers changed from pre covid

Don’t know about Virgin, but where I work the layovers generally tend to be longer during Covid pandemic, as the flight frequency is lower.

Once the pandemic is over I expect most layovers go back to 24 hours, as daily flights are reinstated.

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

To put my 3$ worth into the discussion - I tried to replicate the issue by setting MCP to 0000 on the ground in B787 with TOGA armed (or arming TOGA when MCP was set to 0000) and the mode didn't go to ALT - so it seems Boeing has improved the MCP logic on the 787.

Re: 787 Cruise Mach at Cost Index 300

Re: How soon after takeoff can an airliner safely start a turn?
