Pilots react differently than technicians when they see engine performance parameters.
Their first thought is not "Is this real?" or "How is this achieved?" but rather, "With such an engine, what could a fighter jet potentially achieve?"
For example, the maximum speed.
While others may be impressed that a fighter jet can reach three times the speed of sound, pilots consider whether they can withstand such high speeds and acceleration.
Zhai Licheng, an experienced pilot, concluded upon seeing the engine's parameters, "The J-8B can't test this engine."
"It doesn't have the performance or weight!"
"If the highest acceleration is used, the fighter jet might manage, but I..."
As he spoke, he shook his head and added, "Even the youngest pilot wouldn't be able to handle it."
Zhai Licheng was stating the facts.
