Just think about a balloon or a blimp. At has much more strength with an overpressure in it... The same way it works in an airplane.

Yes but you then won't be able to open a door in case of a sudden evacuation due to the pressure difference.

I dont know. If theres an emergency on groung, the first thing that must be off are the engines. If not, Imagine all those people evacuating through the escape slides and then being sucked by those giant GE 90s

No problem for an Airbus as the door opens by swinging to the outside. In fact, due to the pressure difference, after unlocking the door it opens itself completely.

There have been several accidents with ground workers due to that which is why it is very very important to open the door only if the engines are off.

Last month I have attended an accident investigation where a ground worker tried to open the door of an Airbus with running engine #2 from the outside and he was thrown off the stair by the swinging door. The result were serious injuries.

Anyway I don't want to go offtopic too far.

Hello.

 

First of all, let me introduce myself, I'm kind of new in this forums. I'm a Commercial pilot student form Colombia. I'm really exited about PMDG doing the 777 as my first flight ever was on one 777-200, and that's what made me take the decision to be an airliner pilot 12 years latter.

 

I'm a little bit shamed to ask this, as this should have been discussed milions of times (didn't have luck with the search function). Is there any info on what engine variant is the 777-200LR going to be equipped with. As far as I know. There are two options, GE 90-110B1 and GE90-115B1. Are both variants available? And regarding capacity, the worldliner has three optional auxiliary fuel tanks in the baggage compartments, are them present on this simulation? How much range do that auxiliary fuel tanks add to the basic 777-200LR range.

 

Ok, those are regarding the aircraft engines and performance. Now about the environment effects. Are icing effects simulated? If so, how can I do a de-icing prior to take off? I know the wing anti-ice system of a 777 does operate on ground, only if TAT is above 10 Celsius degrees, but the de-icing procedure can not be replaced with simply applying wing anti ice. And taking off in such conditions is potentially deadly. Are the engines EGT and oil temperatures affected by OAT? And will it take more time to the Oil pressure to rise when the aircraft is in a high temp place like in the real thing?.

 

I also would like to know if the "weight on wheels" limitations are simulated. I mean, in the actual aircraft it is impossible to apply brakes before the main gear make contact with the ground, that extends Brake life. If the cabin pressure on touchdown is still higher that the outside pressure, will the aircraft release the remaining pressure? The "weight on wheels" is also related to the thrust reverses, spoiler deployment,.. But I know it is impossible to apply reverse thrust in the air in an high quality aircraft form PMDG.

 

Well I have more questions, but I think these are enough for a single post. And I want to save some of them for when I have the aircraft. So I can test them. Please be kind in your responses as this post has no harm intention. I just want to know more about this aircraft simulation.

 

Regards

Variant:

 

110B (the 115s will come with the 300ER addon later)

 

YES, auxiliary tanks will be available through PMDG options

 

ICING is simulated but you wont see it on the plane.... because of some fsx limitations and large jets usually dont have large icy buildups anyway...

 

De-Ice is automatic on the 777. leave it on auto and forget about it lol

 

as for the weight and physics, If its on the real thing you can be 99% sure its gonna be in PMDG (unless theres an fsx limitation but PMDG is clever)

 

Have a nice day! Watch the forums for previews

Hello. And what can you tell me about the ice formation on leading edges, will it affect sustentation or just add weight to the aircraft. And is it possible to get a flame out due to nacelle ice?

You 'll feel it (icing) in the handling and you should be able to flame out your engines if you treat them bad enough (its gonna be kinda hard with such powerful turbines)

You just problly wont see the actual ice but your plane will be affected as it would in real life
