I've been searching on the internet about this question and all say you are not able to climb with no excess thrust. But I am wondering that if I have no excess thrust, can I still climb in exchange for slower airspeed?
Like I'm flying 150kts while having no excess thrust (idk if this is possible). Can I climb higher in exchange for 50kts?
"If you have no excess thrust, you cannot climb with constant airspeed. Speed will decrease if you climb. You will be trading speed for altitude." Is the above statement correct? If not, correct me please.
