A220-300 Recurrent simulator preparation

Start with the A220-300 mental model

Prioritise high-value recall, failure recognition and decision discipline on this aircraft means more than collecting facts. Build one connected explanation of the electrical architecture, PW1500G interfaces and fly-by-wire system relationships. Your notes should let you trace energy or information from its source, through distribution and control, to the flight-deck result.

Use the A220-300 / BD-500-1A11 boundary from the beginning. Keep A220-100, software-standard and installed-option differences explicitly labelled. This prevents a technically correct detail becoming a wrong answer when applied to another variant, engine, software standard or installed option.

A five-pass study sequence

1. 01

   Diagnose weak chapters with mixed retrieval.

2. 02

   Repair the two weakest system models.

3. 03

   Rehearse indications before actions.

4. 04

   Chair-fly scenarios using approved procedures.

5. 05

   Protect sleep and use only light recall before the event.

Complete each pass from memory before reopening the source. Retrieval exposes missing links; rereading alone often hides them. Correct the model in your own words, then check it against current approved material.

A220-300 focus points

• 1. Electrical generation and distribution: explain the normal path, the flight-deck indication and what changes after a relevant source or distribution loss.
• 2. Flight-control computers and actuator paths: explain the normal path, the flight-deck indication and what changes after a relevant source or distribution loss.
• 3. Hydraulic sources and major users: explain the normal path, the flight-deck indication and what changes after a relevant source or distribution loss.
• 4. Air, pressurisation and anti-ice interfaces: explain the normal path, the flight-deck indication and what changes after a relevant source or distribution loss.
• 5. PW1500G indications and protections: explain the normal path, the flight-deck indication and what changes after a relevant source or distribution loss.

Do not try to recall all five areas at once. Study each system alone first, then mix two neighbouring systems and ask where they share power, data, air, hydraulic supply, indications or operational consequences.

Use this oral retrieval drill

“On the A220-300, describe the normal architecture, the crew controls and indications, the important automatic response, and the effect of losing one source or distribution path. State any variant or engine boundary before giving detail.”

Answer in two minutes. Draw while you speak. If you reach for a procedure, stop: this exercise tests system understanding, not memory of an operator checklist. Return to the current approved procedure for operational actions.

Common ways pilots waste study time

Copying long notes, memorising isolated components and treating question-bank scores as proof of understanding all create false fluency. A better correction is specific: identify the broken relationship, redraw that part of the system, explain it without notes and retest it after a delay.

Another common error is silent effectivity drift. For A220-300 study, write the applicable model, engine and configuration beside any fact that is not genuinely common. Keep A220-100, software-standard and installed-option differences explicitly labelled.

Readiness check

• I can state the purpose of each major system without notes.
• I can draw normal source-to-user paths.
• I can connect controls, indications, automation and protections.
• I can explain a failure as cue → automatic response → lost function → retained function → consequence.
• I can identify where A220-300 variant, engine, software or operator effectivity changes the answer.
