3: Were the early Learjets susceptible to the mach tuck phenomenon? If so, could a pilot lose control by flying too fast? Is high or low speed at high altitude in a Learjet more likely to lead to a loss of control? Explain. Question 4: To what extent might most current pilot training negatively influence stall recovery? Look at the AF447 accident report for ideas here. Question 5: In your opinion, and based on current training as you understand it, how might most pilots respond to a situation where they are at a high altitude and have a narrow window between their indicated maximum and minimum speeds? Would they bias towards the lower speed or the higher speed and what might be the implications of this? Consider ambiguity bias
