Key points

  • There is no acceptable level of alcohol in your system when flying an aircraft – any aircraft.
  • You really need to check the label to see how many standard drinks are in a given beverage
  • A single shot of spirit gives you about the same amount of pure alcohol as a 330 ml can of beer or a 100 ml glass of wine. They’re all around one standard drink. One standard drink takes around one hour for your body to process.
  • The majority of effects associated with a hangover relate to the brain, the eyes, and the inner ear – all of which are vital when flying.
  • A hangover can last for up to 72 hours after your last drink.
  • CAA Principal Medical Officer: “there is no level of blood alcohol elevation that is compatible with safe aviation, even the slightest increase in blood alcohol leads to levels of measurable impairment.”
