I can't believe what I'm reading either.
Please tell me that these postings are NOT by real airline pilots.
Every schoolboy knows that a conventional aeroplane achieves height by virtue of its forward horizontal motion creating lift.
Actually then every schoolboy is wrong. Lift only counters the weight of the A/C. What makes it go up or down is either excess thrust or a deficit of thrust respectivly. Thats basic aerodynamics - I guess thats too much to ask a schoolboy to know anyway
.
Also every schoolboy knows that acceleration is not speed, it is the rate of increase in velocity.
Yes but if the A/C is standing still on the RWY, don't you have to accelerate to achieve a certain speed?
That is exactly what this is about - do you want to keep accelerating or start climbing. You only have a certain amoungth of energy so how do you want to use it?
