If ventilated patients are being transferred and AGPs carried out, the pilots have the potential to get considerable exposure to AGPs
It is intubation that is a AGP. Once the patient is intubated the airway is isolated and no aerosol produced. Intubation in the cabin must be very rare and is poor clinical judgement. Certainly you would NEVER need to do so on a known Covis 19 positive patient. So if the pilot stays back and wears a FFP3 mask or a reusable mask with a P3 filter plus eye protection there is no risk
