Starting the Aircraft

This guide will assist you with starting your aircraft. It includes images to assist you with understanding the locations of all buttons and switches.

Disclaimer

The level of detail in this guide is meant to teach a FlyByWire A320neo beginner to start the aircraft correctly.

A beginner is defined as someone familiar with flying a GA aircraft or different types of airliners. Aviation terminology and know-how is a requirement to fly any airliner even in Microsoft Flight Simulator.

You will find many great videos on YouTube on how to fly the FlyByWire A32NX.

Chapters / Phases

This guide will cover these chapters in order:

  1. Overhead Panel
  2. Main Panel

Prerequisites

Aircraft is in a cold and dark state at a gate.

Cockpit Preparation

To start off, we will begin by doing a few pre-checks in all areas of the cockpit to ensure the aircraft is in an normal position before turning on the batteries.

We begin by looking down at the bottom pedestal.

We then direct our attention to the main panel and make sure the following is set:

Then we look up at the overhead panel. Make sure the following are in the set position before moving on to starting the aircraft:

  • Wiper selectors are in the OFF position

Overhead Panel

Electrical section

GPU

Batteries

We begin with turning on batteries BAT 1 AND 2. We will hear chimes indicating the batteries are on.

Batteries only power a small part of the aircraft. For the rest either ground power, APU or a running engine is required.

Ground Power

If ground power is available, we should see a green AVAIL light on the EXT PWR button. Push on this button to give power to the aircraft.

Ground Power Not Available

Some gates or stands are not equipped with ground power. In Microsoft Flight Simulator this happens regularly at smaller airports. This is not a bug but a realistic situation. You can then either try to call a Ground Power Unit (GPU) if available at the airport or just use the APU as described in the next step.

APU

If ground power isn't available, we turn on the APU now.

To do this, we simply push on the APU MASTER SW and START. The APU should be on within one minute.

APU Start

COVID SOP

APU BLEED

Many airlines require the air conditioning to be running prior to passengers entering the aircraft, and remain on until deboarding is complete to ensure proper air circulation. Therefore, turning on the APU even with ground power is now required, as the air conditioning packs need the APU Bleed air to function whenever the engines are not running. Especially if a ground air conditioning unit is not available.

Make sure to turn on APU Bleed on the overhead panel.

Engine Start

APU Bleed Air is required for starting the engines. See Engine Start and Taxi

Real World APU and A/C Start Procedure

The above process is a simplified version of how real world airline start up the APU (documented in their SOP - Standard Operating Procedures).

Here is a description of an actual real world procedure of a well known airline.

  • Check A/C Packs are OFF before powering the aircraft
  • Set APU MASTER switch to ON
  • Press APU START
    • Some airlines still require the pilot to wait 3sec for the APU flap to open. This is no longer required in the A320neo as the startup sequence waits for the flap to be open automatically.
  • Wait until APU START button shows "AVAIL" (or check on lower ECAM APU page)
  • Wait 1 min (use CHRONO to time this)
  • Set APU BLEED to ON
  • Wait 1 min (use CHRONO to time this)
  • Set PACK 1 to ON (due of COVID many airlines require both A/C PACKS to be ON)

The two waiting steps are to avoid any APU oil fumes to get into the air conditioning.

Crew Oxygen Supply

After powering the aircraft, we turn on the crew oxygen supply by pushing on the button, diminishing the white OFF light.

ADIRS alignment

To align the Inertial Reference System (or IRS), we turn the 3 knobs to the NAV position. This will then start the IRS alignment for which we can view the progress on the ECAM display.

ECAM IRS

Exterior Lighting

To indicate that the aircraft is powered from the exterior, we turn on the NAV & LOGO light.

Following this, we set the STROBE light to the AUTO position.

Exterior Lights

Tip

Overview of External Lighting configurations

Interior Lighting

Cabin

We can turn on a few lights to help with visibility inside if it is too dark inside the cockpit.

Internal Lighting

  • The DOME light has 3 settings to choose from. We can set it into the OFF position, the DIM position, or even the BRT position.
  • The OVHD INTEG LT will allow us to see the outlines of the overhead panel. Turning the knob will adjust its brightness.

Passenger Signs

Passenger Signs

  • Seat belts sign - Set to ON
  • No smoking sign - Set to AUTO
  • Arm the emergency exit lights - Set to ARM

Real World Procedure

The Seat Belts sign is not turned on until fueling is complete.

Cabin Pressure

Cabin Pressure

Looking up just a bit we find the LDG ELEV knob. This simply means the landing elevation which should be in the AUTO position.

Cabin Temperature

Air Conditioning

Managing the temperatures of the cabin is necessary as well. Simply rotate the 3 knobs as needed.

Hydraulic and Fuel Section

Looking up at the hydraulic panel, we ensure that there are no white lights visible.

Fire Tests

To perform an APU and Engine fire test, hold down the TEST button for each of them for 5 seconds minimum to ensure the lights and aural warnings are working as expected. Checking the ECAM during the test will also show if the ECAM is performing as expected during a fire.

Fire Panel

Just below the hydraulic panel, we find the fuel panel. Turn on all 6 fuel pumps until the white OFF light is no longer visible.

Fuel Pumps

Main Panel

Displays

The brightness for each display can be adjusted to make them better readable.

For the PFD and ND, the knobs are in the same location. Look left (or right when in first officer seat) of the PFD and find the brightness knobs for them. Simply turn both knobs as required.

PFD and ND brightness

For the ECAM upper and lower display, look just in front of the throttles and find the brightness knobs. Just like the PFD and ND knobs, rotate them as required.

ECAM brightness

For the ISIS display brightness (just left of the upper ECAM), use the + and - buttons until the brightness is suitable. While we are at the ISIS display, set the current QNH.

ISIS

Radio Panel

Looking down at the radio panel, set the RMP 1 to the active ATIS frequency and set the standby frequency to the ground frequency.

Radio Panel

After setting correct frequencies, locate the BARO reference on the glareshield. We can set the barometer to either inHg or hPa by turning the grey inner selector behind the knob. For this flight ensure that we are set to QNH. This can be changed by "pushing" on the BARO knob (the tooltip will have an upwards arrow).

A note on QNH and QFE

Choosing between using QNH and QFE is a little beyond the scope of this guide. In most cases we will be flying using QNH.

  • QNH: Altimeter indicates height above sea level.

  • QFE: Altimeter indicates height above reference elevation in use (airfield or touchdown). This setting is usually tied to a procedure in use by the airfield, where when on the ground the altimeter will read 0.

Just below the barometer reference, turn on the FD. A green light indicates it has been turned on.

EFIS Control Panel

ECAM Fuel Page

Verify on the Upper ECAM that your aircraft has enough fuel for the flight.

ECAM Fuel On Board

If we do not have enough fuel for the flight we can refuel via the flyPad EFB Fuel Page .

At this point we would have completed 5/7 task on the Before Start section on the FlyByWire A32NX checklist.

Before Start Checklist

This concludes the Starting the Aircraft guide.
