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.
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...Jump to post
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 ...Jump to post
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...Jump to post
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, ...Jump to post
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...Jump to post
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 ...Jump to post
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.

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 ...Jump to post
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...Jump to post
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...Jump to post
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...Jump to post
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...Jump to post
From Volume 2, section 15, Warning Systems, of the B777 FCOM for multiple airlines: Landing Configuration Warning The landing configuration warning system alerts the crew the landing gear is not extended for landing.

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...Jump to post
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.

Oceanic clearances are still available on VHF. Shanwick (UK) still has a dedicated Oceanic Clearance Delivery frequency. Gander had one until recently, nowadays they issue clearances on domestic ATC frequency to whomever has no datalink. Most clearances come via ACARS. I used to do HF reports as lat...Jump to post
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.Jump to post
EASA rules specify minimum turn height of 50' or half of the wingspan, whichever is greater (with bank angle limited to 15 deg until 400'). Hoever normal ops is 400'Jump to post

It does in terms of general step climb procedure. However, both 787 and A350 will start higher (approx 36,37 at MTOW) and will climb higher a bit quicker. In many cases up to F430, depending on ZFW. Cheers, Adam A heavy 787 will start at approximately FL330, not sure about the A350. 430 will only b...Jump to post
Another thing to consider is APU start cycles - sometimes it’s cheaper to keep it running, rather than shutting it down after taxi in and re-starting it before departure. However, it’s a bit of black magic, depending on airline maintenance contracts etc, company policy, price of ground power at a pa...Jump to post
One difference is that Airbii don’t have wheel well fire detection systems and have a 300 deg C brake temperature limit for takeoff, in order to prevent fire in case of Hyd fluid leak. This 300 degrees limit is quite easy to exceed on landing and the brake fans are there to dissipate the heat on sho...Jump to post
It can get even better! We sometimes operate Longhaul charters and the crews get to spend a week (occasionally more) in a 5-star all-inclusive resort.

Pushing TOGA on takeoff is not the same as TOGA takeoff... Boeing airplanes also use reduced thrust for takeoff - they just call it ATM instead of FLEX, but the basic principle is the same. Pushing TOGA button before takeoff make the thrust levers advance to the previously programmed thrust setting....Jump to post
What is worth noting, fuel flow is more or less directly proportional to the thrust produced by engine, regardless of altitude. i.e. the engine will produce (roughly) the same thrust for given fuel flow, regardless of altitude - although at different N1 This is not entirely correct, especially for t...Jump to post

Because iPads seem to be doing a better job than built-in, original EFB. Also, they are normally issued to pilots on all fleets, whereas the manufacturer EFB's are airplane specific - there is a different one on say A350 and a different one on the 787 and there's none on other airplanes.

Apart from other considerations (structural limitations, optimum level, emergency descent mentioned earlier), your Max FL may be aerodynamically limited (not enough wing), or thrust limited (not enough thrust to climb and/or sustain level flight with adequate manoeuver margins).
