I am trying to find out for a friend who is currently training who has just scraped through with his hearing test (not me...mine is fine). The CAA website says that for someone who is issued a Class 1 medical, the following limitations apply:
The frequencies that have to be tested are 500, 1000, 2000 and 3000 Hertz (Hz), and the maximum allowable losses is shown below:
500Hz
35 dB
1000Hz
35 dB
2000Hz
35 dB
3000Hz
50 dB
From what I am told, he managed to just get on the 35dB. Do airlines have any specific requirements, or will he be fine how he is?
