Hello! 

 

I've watched a lot of tutorials to start flying ultra-complex Boeings (PMDG 777-200 and PMDG 737-800NG), but always during takeoff, they were saying either: increase thrust to ~40%, press TO/GA and release parking brake (737) or increase thrust to ~55%, wait for it to stabilize and press TO/GA [without setting parking brake on runway] (777). And I also saw proffesional pilots do it in real life. But why? How does it help? Is it necessary?

 

Also, below FL100, pilots turn on Engine Start Switches To 'Continous'. It gives more chances, to keep the engine running, during the bird strike. But if it's so good, why do pilots turn it off above FL100?

 

And one more thing, during flight, Engine Oil, and Hydraullic Fluid slowly decrease over time. But when you end your flight and close the game, do those variables some kind of 'save'? Is there a reason to check those values constantly during preflight checklist? (in flight simulator, like FSX)

 

Any help would be much appreciated!

Thanks!

At lower RPM engines have stability bleed valves and variable stator vanes to prevent things like compressor stall. If you slammed the throttles from idle there is a risk a bleed valve might not close or the vanes might not open and that engine would accelerate slower, leading to a thrust differential at takeoff thrust. So the usual procedure let the engines stabilise at around 60% (also known as standing the throttles up) to ensure bleeds are closed before setting takeoff thrust.

 

If you run ignition continuously the whole flight the igniters will soon wear out. So you use ignition in critical phases of flight and when a flameout is likely (in cloud or precipitation).

 

If you save the panel state after each flight and restart from that state, fluid loss will be carried over.

So, after you get to the gate, you shutdown the airplane and click "PANEL STATE SAVE"? Next time you enter the aircraft, you load the save? And that's it?

Thank you! I figured it out!
