We didn’t get that information before we leave HKG.

We are approaching minimum fuel

The winds didn’t work out as as forecast crossing the pond.

crossing the pond– Often used to go to USA to the UK, and vice versa. Basically, an other word for the Atlantic Ocean

[Crew Briefing]

“SEA-ICE” Method

  1. Safety and Security issues and considerations
  2. Equipment issues (INOPS?)
  3. Abnormal procedures
  4. In case of Emergency (ICE)

Important notes

  • PIC sets the tone
  • Always close with “Any questions?”

 

SEA-ICE on Arrival

Arrival briefing is helpful for focusing on what might get missed. Some elements should be included:

  1. Current and expected WX conditions (come from current WX and NOTAM reports) MUST be considered
  2. Flight instruments, FMCs, NAV and COM radios, and other avionics MUST be programmed and set up
  3. A verbal approach briefing MUST be exchanged between the pilots

Indeed, the cockpit crews need to make a briefing to cabin crew as well –  NITS brief  would be helpful:

  1. Nature of the problem
  2. Intention
  3. Time needed – to sort out the problem
  4. Special instructions if required (Safety and Security)
  5. Do you have any questions?

Example

(ISM/CSM’s name), we have a suspect to technical problem. We were getting a fire warning in the rear cargo hold. We are going to be diverting to (somewhere). We have approximately 20 minutes to landing. As we start to descent, the smoke may potentially come into the cabin. After the aircraft lands, I’ll give you the command to evacuate if I think we need to make an evacuation drill or unless you feel that the situation is catastrophic then you start the evacuation by yourself. Do you have any questions?    

  1. Nature of the problem – fire warning in the rear cargo hold
  2. Intention – diverting to (somewhere)
  3. Time needed – approximately 20 minutes to landing
  4. Special instructions if required (Safety and Security) – 
    smoke may potentially come into the cabin as we start to descent;

    PIC will give command to execute evacuation OR ISM/CSM feel that the situation is catastrophic then he will start the evacuation
  5. Do you have any questions?

 

 

 

Briefing of En-route situation – turbulence 

Example

(ISM/CSM’s name), thanks for noticing the seat belt signs have been illuminated (= seat belt signs have been put on = seat belt signs come on).  They come on because we are going through some bumpy air at the moment. The catering service can remain, but please don’t serve any hot drinks at the moment Also, please help the PAX return to their seat and fasten their seat belt securely until the signs have been switched off . And I will make the PA as well. Do you have any questions?

  1. Nature of the problem – we are going through some bumpy air at the moment
  2. Intention –
    catering service can remain, but please don’t serve any hot drinks;
    help the PAX return to their seat and fasten their seat belt securely
  3. Time needed – until the signs have been switched off
  4. Special instructions if required (Safety and Security)  – I will make the PA
  5. Do you have any questions?

Example – nose gear fail to extend

Language

We have tried recycling the gear, but we still have a red light.

We plan to come in for a low pass (= make a low pass).When we pass over, could you check out (=inspect) our landing gear?

When we get to you, the gear should be down.

We’ll try to lower the gear again, but if we are still unable to release the nose gear (= if it is still stays up), then we’ll land with all three up.

Please check if some birds stuck in the mechanism.

It could be that we swerve to the left on landing – be aware that we could come off the runway to the left, EVA 852.

Example – Medical Emergency

Can you confirm the age and sex of the patient, please?
EVA852, PANPAN, it’s a flight crew member. It’s a 1966 male.
Can you just confirm if the patient has had seizures (癲癇發作) and if he is conscious at the moment?
It was a pilot and we are two capable pilots (have two active pilots) in the flight deck at the moment
134.260, was that?
EVA 852, can we expect a jet bridge or remote stand?
Do you have a tow bar that fits the 787?
I’ll double check it.
We just prefer whatever is the faster way.
There is a SIGMET in force, SEV TURB FCST

I have question to you
Is there such a gate?
We have got a A380 coming in here in about 45 mins with a medical emergency
I don’t know that part yet. I just get word that they’re coming in with some sort of medical issue
Ok, I’ll call down and let them know.
(call down = To call by phone or yell to someone)
EVA 852, could we take the landing wind? = windcheck please?
Our chart say that we can take A2 and A1. Could we do A2 A A1 back onto the RW 22?
Affirmative, that works also.
You can turn left at A2 join A and then A1 back onto RW30L
I will be your lead
Pull up on runway = flare
Which door would you like us to use?
Just give us a countdown and we’ll slam the brakes on
Can you do that in (meter/ a unit like km)?
Please give us few minutes to shut the engine down.
EVA852, we are shut down, you can approach the aircraft.
Hi there, just didn’t know if you were still there or not.
We are hoping to go in about 45 minutes.

The video below is quite useful for listening practice:

[Describe and discuss a photo]

Always imagine that you are talking to someone who can’t see the picture.

To tell others about the relative position on the picture, we could use the language below:

  • In the top (left/right)
  • At the top
  • In the center/ middle
  • On the (left/right)
  • In the bottom (left/right)
  • At the bottom

OR

Source: https://www.tes.com/lessons/OQ3dhfpLUjYzMg/copy-of-story-quilt-collage
  • In the foreground
  • In the mid-ground / In the middle ground
  • In the background

Also, try to use some language to elaborate your idea:

  1. There is…
  2. There are…
  3. The picture shows…

In addition, you could add your feeling:

  1. I suppose
  2. Maybe…
  3. It [must]…
  4. Perhaps ….

Example: 

Obviously, the photo (above) is the screen snap from a footage. There is a control bar at the bottom of the image and there is a red subscription button in the bottom right. I suppose it is one of the youtube video clip. The image shows “in the center” at the middle and “at the top” above and “at the bottom” below. I guess the author is trying to take a record for learning.
