Which risk dramatically increases as a high-bypass turbofan engine's bleed air demand rises during flight?

💡 Explanation

Increasing bleed air extraction reduces pressure available to the core, because this decreases the "compressor stall margin", therefore engine stall becomes likelier; rather than fuel savings, bleed air increases core load, increasing fuel burn.
