Dear New on NG, I have just sent a private message to you. It is some contact information on a specialist, also a freind, in San Paolo who can help you with specific study on this matter.
An example of what
not to say, and proof of the necessity to study these things, in/for an emergency: A320 Captain, pilot flying, lost hydrauic power immediately after take-off. He, a non-native speaker (albeit operationally proficient speaker), said to a EFL ATC (with a very low level in English langauge proficiency), "I've lost hydraulic power in engine number one". The ATC understood only these words "LOST ENGINE ONE". The mayhem that ensued is unbelievable. The tower continued calling the flight deck to clarify, asking if they needed emergency equipment, etc. It interrupted the pilot and distracted him from his concentration of trying to resolve the problem on board.
Happily, everything went well and the pilot was able to land safely. Reflecting upon this situation the Captain realized he should have just said, "Lost hydraulic power, request priority landing".
All the best,
Plane English
