C) increased blood sugar levels.

  • When an inexperienced pilot, or anyone for that matter, prepares for an emergency situation, the body activates what is known as the "fight-or-flight" response. This response is triggered by the sympathetic nervous system and leads to a series of physiological changes that prepare the body to either face the threat or flee from it.
  • One of these changes is the release of adrenaline (epinephrine) and cortisol into the bloodstream, which among other effects, signals the liver to convert glycogen into glucose, thereby increasing blood sugar levels. This provides quick energy to the muscles and brain to handle the emergency.
