This test contains 3 situations that you can choose from the menu on the left hand side of this page. Always try to answer before reading the expected answer!
PILOT: HONG KONG GROUND, CHINA EASTERN 831, WE’VE REALIZED THERE IS A PASSENGER CARRYING DANGEROUS GOODS. IT’S NOT ALLOWED TO BE CARRIED IN THE PASSENGER CABIN. WE INTEND TO RETURN TO THE GATE.
ATC: CHINA EASTERN 831, YOU ARE CLEARED TO RETURN TO GATE THREE VIA TAXIWAY ALFA.
EXAMINER: Now tell me in your own words everything the pilot and controller said.
I understood the pilot said they had a passenger on board that was carrying dangerous goods that were not allowed in the passenger cabin and he requested to return to the gate.
The controller said that CHINA EASTERN 831 was cleared to return to the gate via taxiway alfa.
EXAMINER: What are the dangers of carrying dangerous goods.
Dangerous goods pose many dangers as they can explode, cause fire, smoke and fumes on board.
EXAMINER: Now listen to situation number 2.
PILOT: DUBAI CENTER, SKY DUBAI 972, WE HAVE A FIRE IN THE ELECTRICAL SYSTEM. WE HAVE SHUT GENERATOR 2 DOWN. THE NAVIGATION SYSTEM IS COMPROMISED.
ATC: SKY DUBAI 972, SQUAWK 7700. CONTACT DUBAI APPROACH ON 122.40 FOR FURTHER INSTRUCTIONS.
EXAMINER: Now tell me in your own words everything the pilot and controller said.
I understood the pilot informed Dubai center they had an electrical system fire and they shut down generator 2 and consequently their navigation system was compromised.
The controller said squawk 7700 and told SKY DUBAI to contact approach on 122.40 for further instructions.
EXAMINER: What are the outcomes of an electrical fire?
The outcome of an electrical fire can be terrible as it can cause smoke and fumes in the cockpit and even a disaster.
EXAMINER: Now situation number 3.
PILOT: MAYDAY MAYDAY MAYDAY, MIAMI CENTER, UNITED 458, WE ARE DESCENDING TO FL 100. WE’VE HAD A DEPRESSURIZATION. WE ARE LEAVING FL 310 TO FL 100.
ATC: UNITED 458 , ROGER, TURN LEFT HEADING 270. REPORT REACHING FL 100.
EXAMINER: Now tell me in your own words everything the pilot and controller said.
I understood that the pilot declared an emergency to Miami center and said he was descending to flight level 100 due to a depressurization. He informed the controller he was leaving flight level 310 and descending to flight level 100.
The controller understood and told UNITED 458 to turn left heading 270 and to report reaching flight level 100.
EXAMINER: What are the threats of depressurization at a high flight level ?
The threats of a depressurization at a high flight level can be terrible as it can cause a lot of injuries on board and even lead to a disaster.
EXAMINER: Now, considering the three situations you have heard in part three: How would you compare them? You may want to compare them in terms of severity, possible solutions and ways of prevention. Which one do you think is the most difficult to deal with? Why?
In my opinion the passenger carrying dangerous goods is the least serious situation to deal with.
The depressurization is worse than the passenger carrying dangerous goods as it’s an emergency situation and can easily lead to a disaster.
But the fire in the electrical system is the worst to deal with as the fire can spread quickly and cause the aircraft to crash so the pilots must make the right decisions quickly.
EXAMINER: Thank you. That is the end of part three.
