I read with interest and obvious necessity for possible future application, your article on hypoxia, Get Your Mask On, in December, 2014.I fly a Malibu Mirage PA 46. Ive had several decompressions in the low 20s that were attributed to squat switch/pressure switch failures. Ive now added another immediate action to pressurization problems:
During a decompression, immediately don the oxygen mask before configuring aircraft descent, as it requires less cognitive function and counteracts the insidious onset of hypoxia.
Pilots must correctly set their altimeter, even though transponder Mode C broadcasts altitude against a standard datum (29.92), because Air Traffic Control applies local barometric corrections to display accurate altitudes.
When approach chart notes are ambiguous or contradictory regarding restrictions (e.g., "NA at night" with specific conditions), pilots should interpret them as applying the most restrictive condition.
Tail stall recovery is counter-intuitive compared to a main wing stall, requiring pulling aft on the yoke, retracting flaps, and reducing power to decrease the tail's angle of attack, especially when encountering icing.
Lower Altitude or Mask First? I read with interest and obvious necessity for possible future application, your article on hypoxia, “Get Your Mask On,” in December, 2014.
