The L-39's service ceiling is 36,100 ft / 11 km but would it be able to easily reach and surpass 40,000 ft MSL if flying a parabola?

  • $\begingroup$ I doubt it. The L-39 is a relatively docile training aircraft that some operators have used for ground attack, but the thrust to empty weight ratio is a pitiful 0.49. Put some fuel and a pilot in it and it gets worse. Many refer to it as an aircraft for fighter pilot "wannabe's" with not enough money or experience to fly a more powerful warbird. $\endgroup$ Oct 9, 2021 at 2:57
