De-Icing Procedures


FS2Crew for the Aerosoft Airbus models de-icing procedures both at the stand and at remote pads.

Notes:

You should radio the de-icing coordinator at least 15 minutes prior to engine start to coordinate de-icing.

IMPORTANT (REQUIRED COMM RADIO FREQ):

To communicate with the de-icing crew on the radio, you must set COMM RADIO 1 or COMM RADIO 2 to 121.65.



To initiate the conversation with the de-icing crew, using the following trigger phrase, which must be spoken separately and clearly from any other phrases so the speech recognition system can easily detect the phrase..

 “REQUESTING DE-ICING”.

Example:  "De-Ice Coordinator, it's American Flight 24... requesting de-icing."



The De-Ice Coordinator will respond "Go Ahead."  You will then tell the De-Ice Coordinator what your requirements are for de-icing and your estimated departure time in 'Zulu' time.

The trigger speech phrase to close the conversation is “ZULU TIME”.

Just prior to de-icing and if you want to de-ice at the gate prior to engine start, command the FO to prepare for de-icing by speaking:
“PREPARE FOR DE-ICE”.

Note that if you are de-icing at a remote pad, you would speak “PREPARE FOR DE-ICE” just prior to the start of de-icing procedures.  That's the trigger for the FO to start his flow.

FO's Flow:  
  1. CAB PRESS MODE SEL AUTO (Not currently modeled in the Aerosoft Airbus)
  2. ENG BLEED 1 + 2 OFF
  3. APU BLEED OFF
  4. DITCHING push button ON (Not currently modeled in the Aerosoft Airbus)
  5. GND COOL OFF (Not currently modeled in the Aerosoft Airbus)

Captain's Flow:
  1. THRUST LEVERS IDLE


The FO will leave the APU running if it is already on.  If you wish to have the APU off during de-icing, you must manually shut-it down, however, ensure the ground power is connected or you will lose power.  If you’re at a remote pad, leave the engines running.  Make sure Wing Anti-Ice is 'off'.

After the FO has completed his de-icing flow, speak: “DE-ICE COORDINATOR WE ARE PREPARED FOR SPRAYING” to tell the De-Ice coordinator that you’re ready to start the de-icing.

The de-icing team will then de-ice the aircraft.  This procedure takes approximately 3 minutes.



When de-icing is complete, the De-Ice Coordinator will radio you, and provide you with his employee number, the start and end time, etc.

Speak “THANK YOU FOR YOUR HELP” to disconnect the De-Ice Coordinator; that phrase is also the trigger for the FO to configure the aircraft after the de-icing.  

  1. DITCHING pushbutton OFF (Not currently modeled in the Aerosoft Airbus)
  2. ENG BLEED 1 + 2 ON

 
Note that the FO will wait one minute before before turning the bleeds back on to prevent de-icing fumes from being ingested into the aircraft.  Please be patient during this period. 

As Captain, you need to:

  1. APU BLEED SET AS REQUIRED (You may want to consider leaving the APU Bleed Off for takeoff due to the possibility of de-icing fluid ingestion.)
