# Preflight Setup (Quick Guide)

Step-by-step MCDU preflight from **RADIO** through a complete route, departure and arrival procedures, performance initialization, and takeoff speeds.

Example route: **EGLC/27** N0317F210 ODUK1A ODUKU M84 CLN P44 RATLO M197 REDFA REDF1A **EHAM/18R** (SimBrief / datalink import).

{% hint style="info" %}
Complete **NAV IDENT** once before using **RTE**, **FPL**, or **PERF** (verify the AIRAC cycle; update via [Navdata Updater](https://docs.flightsim-studio.com/e-jet-series/special-features/electronic-flight-bag/navdata-updater) if needed). Store your SimBrief username before route import. Keep the **EFB manifest** open for ZFW, fuel, **TO CG**, and V-speeds.
{% endhint %}

{% hint style="danger" %}
On **PERF INIT 3/3**, you must press **CONFIRM INIT>** before the FMS calculates the vertical profile (TOC/TOD) and VNAV data.
{% endhint %}

## Step 1

{% columns %}
{% column width="64%" %}

1. Enter the airport ground/delivery frequency (or the first frequency you will contact) on **RADIO**.
2. Enter the follow-up frequency in standby.
3. Press **RTE**.
