Questão 2 de 25

1

Which of the following refers to Bernoulli's principle

Selecione uma das seguintes:

  • For every action there is an equal and opposite reaction

Questão 8 de 25

1

What must a pilot be aware of regarding ground effect?

Questão 10 de 25

1

During the pre-flight the pitot heater (if fitted) should be checked

Selecione uma das seguintes:

  • If flight into known icing is planned

  • Turning is on and letting it run

  • By turning it on briefly and feeling for it to start warming up, then turning it off

  • The pitot heater must not be turned on while on the ground

Explicação
