If you search the various file libraries, here and over at avism you can find POH's for different aircraft. You will have to learn how to read and understand the engine guages on different power plants. On piston engines, the primary gauge for measuring engine performance is MAP preasure guage. There are two useful ones on turbines, the torque gauge, and the ITT gauge. On jets, the primary monitored engine parameter is the N1 guage. In fact, the N1 value is what FMC's control primarily when they are set up to do de-rating, which is a fuel, wear and tare and therefor money saving function. If the plane is lightly loaded, the pilots are able to program the FMC for a reduce take-off power. The reduced power settings are typically on tables from the manufacturer found in the plane's POH. But, that is probably getting a little deeper than you need at the moment. Only really useful to know when you get into complex payware add-ons like 738 NG, 747 QOS, Level D 767, ERJ-145 PIC, or CRJ Experience. What I'm basically trying to say is that manageing your power in this manner is wholly realistic to how it's done on the real planes. Each plane out there has power/flightregime tables which pilots follow. Yes, they can physically see how far their throttle control is applied but that's not what they go by, they fly according to the published numbers and watch those gauges. Typically, the engine gauge you will need to go by, whether it be MAP, torque, or N1 will have yellow and red zones, much like a tachometer on a car. If you download a POH for that plane and compare the published numbers with the way the gauge is marked typically you will find them right in line, of course altitude has an effect to. You might be flying the engine in it's designed limits but it could still be to fast, to low for the airframe design. Once again, the published numbers for a plane tell you what speed/altitude number to flollow to avoid overspeed warnings and such. Even military fighters can overspeed/overstress if to fast to low, It's just their limits are higher becaudse they are built for speed and manueverability. Keep us posted on you lessons and flights, we will help you all we can. Simv is a flying family and incidently, there are a number of liscensed private and airline pilots in the family. You've come to the right board. Happy landings.
