[quote]That makes sense.. sorta ..

So you can set the auto-throttle for N1 instead of airspeed ?

So mostly.. it's a FMC thing.. not near as simple as in the sim.. (actually simpler to the actual REAL heavy pilot)

Believe it or not.. it makes sense to me..

I was having trouble picturing just dialing in an airspeed and constantly, manually changing vertical speed to keep the engines happy..

Care to elaborate on that?
Just interested in what you mean, that's all.

In a Cessna 172 it's full throttle, pitch for an airspeed.

In a jetliner, it's pitch to maintain a specific fan speed that will give you a specific airspeed.  It's slightly more complicated since you don't just go full throttle.

Of course, in most modern planes, the FMC controls the VS automatically (I believe).  For non-FMC planes in FS, we must control the VS and decrease it manually to maintain a certain airpseed without overstressing the engines.

The EEC in the aircraft will not let the max N1 overstress the engine.
Hence you can firewall the throttles in a 737 and you'll get away with it.  Another luxury of flying in the digital age.

So when you push the N1 button on the MCP (autopilot panel), the aircraft will climb on FULL POWER current available and pitch is dependant on the airspeed selected by the crew.

I understand your reasoning, but my instructor would never use that as a classroom example, but again he flies airbus so they are all little weird  ;)

Interesting, thanks for clearing that up :)

Then let me rephrase.

In Flight Sim without an FMC... everything I just said. ;)
