Takeoff, Climb and Cruise

This guide will explain the correct procedures to accomplish takeoff, climb and establish cruise altitude.

Disclaimer

The level of detail in this guide is meant to get a FlyByWire A380 beginner safely up in the air and to cruise level under normal conditions, while simplifying details which are not (yet) important for a beginner.

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.

Quick Start

MSFS Start from Gate or Runways

Microsoft Flight Simulator allows you to start your flight from cold & dark at a gate or directly from the runway with the aircraft ready for takeoff. For this guide, we assume you started cold & dark at the gate and taxied to the runway holding point as per the previous chapters of this beginner guide. If you did start on the runway, you can skip the first part (Lineup) and directly continue reading Takeoff.

Prerequisites

Aircraft is in TAXI state as per previous chapters.

Base Knowledge About the Airbus A380 for Flight

This section is focused on differences to other non-Airbus airliners a user might be used to.

What is a Fly-by-Wire System?

Traditional mechanical and hydro-mechanical flight control systems use a series of levers, rods, cables, pulleys and more, which pilots move to adjust control surfaces to aerodynamic conditions. Their "hands on" design gives pilots a direct, tactile feel for how the aircraft is handling aerodynamic forces as they fly. On the other hand, mechanical systems are also complicated to operate, need constant monitoring, are heavy and bulky, and require frequent maintenance.

In fly-by-wire systems, when the pilot moves flight controls, those movements are converted into electronic signals, which are then interpreted by the aircraft's Electrical Flight Control System (EFCS) to adjust actuators that move flight control surfaces. Computers also monitor sensors throughout the aircraft to make automatic adjustments that enhance the flight.

Because fly-by-wire is electronic, it is much lighter and less bulky than mechanical controls, allowing increases in fuel efficiency and aircraft design flexibility, even in legacy aircraft. And to prevent flight critical failure, most fly-by-wire systems also have triple or quadruple redundancy back-ups built into them. source: BAE Systems

1. Lineup

Situation:

ATC (Ground or Tower) has instructed us to hold at a runway holding point and wait until we are cleared to "line up" or "take off".
Aircraft is still in TAXI state (see previous chapters) and parking brakes are set.

TODO: update screenshot with 380

Typically, it is here at the latest that we are asked to switch to Tower ATC frequency for takeoff clearance.

TAKEOFF OR LINEUP CLEARANCE ....................................... OBTAIN
EXTERIOR LIGHTS ...................................................... SET
TRAFFIC ............................................................... ON
TA ...................................................... TA ONLY OR TA/RA

While approaching the runway holding point or at the latest at the runway holding point the "Before takeoff checklist" needs to be completed.

Before takeoff checklist

TODO: update checklist

The "Before Takeoff" checklist is divided into two parts: Down to the line, or Below the line.

"The Line" Definitions

"Down to the line" (or "Above the line") means before "ATC Takeoff Clearance".
"Below the line" means after T.O. clearance (when lined up) but before starting the roll.

Preparation and "Down to the line" Checklist pre-T.O.-clearance

The following steps from TAXI setup need to be done and checked:

Check OVHD panel: APU off, no lights visible under normal circumstances
(exception: Pack 1+2 might be OFF if part of procedure) {loading=lazy}
TODO: update OHP screenshot

OVHD PANEL ............................................ CHECK DISCONNECTED
APU .................................................................. OFF
APPROACH PATH ..................................... CHECK CLEAR OF TRAFFIC
STROBE LIGHTS ......................................................... ON

Advise Cabin Crew

TODO: update screenshot with new CALL panel
- The cabin crew will notify the pilots with a "Cabin Ready" button once they are ready for takeoff.
- In the FBW A380, this is simulated by pressing the CALLS ALL button on the left of the overhead panel.
- This will set the "Cabin Ready" status as shown in the ECAM.
Check Squawk

SQUAWK ID NUMBER ................................................... CHECK
SET SQUAWK .................................................... AUTO OR ON
SET ALT RPTG .......................................................... ON
COMM FREQUENCY ..................................................... CHECK

Check ECAM - NO blue writing should be visible for these:

AUTO BRAKE ............................................................MAX
SIGN ...................................................................ON
CABIN ...............................................................READY
SPLRS .................................................................ARM
FLAPS ..................................................................TO
TO CONFIG ..........................................................NORMAL

TODO: update screenshot with new ECAM

Press T.O. Config button below the ECAM to check takeoff configuration
Check radar panel:

TODO: update screenshot with new radar panel

Weather Radar Panel

Set Weather Radar to Sys 1 to show weather on ND

Check if Predictive Windshear Alerts (PWS) is set to AUTO (should have been set to AUTO during TAXI)

Entering Runway

Before we start rolling, we visually check that no other aircraft is on final approach. We can also use TCAS on the ND to check for aircraft in the vicinity.

If everything is clear, we release the parking brake and slowly roll onto the runway in the direction of takeoff and come to a stop on the runway's center line.

There is also a rolling start, where we would not stop but directly apply thrust for takeoff once we are straight on the runway. But, as a beginner, a full stop is recommended so we can double-check everything.

When we reached our starting point, we stop and set the parking brakes.

TODO: update screenshot with 380 exterior

If we were only cleared to "line up" we wait here until we get clearance to take off.

This concludes Lineup.

2. Takeoff

Situation:

Aircraft is on runway and fully setup for takeoff as per previous chapters.

Preparation and "Below the line" Checklist post-T.O.-clearance

After ATC (Tower) gives clearance to "line up" or "take off" we are allowed to enter the runway.

To "line up" means that we roll onto the runway and stop at our starting point. We MUST wait for ATC to give us "takeoff clearance" before we can continue.
"Cleared for takeoff" means we are allowed to actually start the takeoff when aligned with the runway.

Shortly before we start our takeoff roll, we do the following steps:

PACKS .......................................................CHECK AS REQ.
(some airlines take off with Packs OFF to allow more power to thrust and save fuel - not necessarily required)

Turn on landing lights (LAND) and check if STROBE light is in AUTO or ON

TODO: update screenshot with new lighting panel

The correct switch settings are:

RWY TURN OFF ...........................................................ON
NOSE ..................................................................T.O
LAND ...................................................................ON
STROBE .................................................................ON
BEACON .........................................................NAV & LOGO
WING ..................................................................OFF

Lights at Takeoff

Setting the RWY TURN OFF light to ON, the LAND lights to ON and the NOSE light to T.O. minimizes bird strike hazard during takeoff.

Check ENG MODE SEL as required (should be on MODE NORM)
Set TCAS to TA or TA/RA and traffic to ALL or ABV

A typical standard takeoff follows these steps:

Airline SOPs

Some airline's SOPs (standard operating procedures) might have a different order for these steps.

Release parking brake and hold down manual brakes.
Apply thrust slowly to about 25% N1 until both engines are stabilized (N1 stays constant at around 25%) while still holding the brakes.
Push sidestick forward half the way to put pressure on the front gear

Release brakes and apply FLX/MCT or TO GA power.
(depending on if you have configured a FLEX temperature, and the runway is long enough for a FLEX start)

TODO: update screenshot with new ECAM

The PFD Flight Mode Annunciator (FMA) now shows several things which we should check when the aircraft starts rolling:

From the left:

Thrust: set to MAN FLX + 60
Vertical guidance:
- Active (green): SRS (pitch guidance to maintain V₂ + 10)
- Armed (blue): CLB mode (is next after SRS is done)
Lateral guidance:
- Active: RWY (automatic runway axis follow up through ILS use)
- Armed: NAV (navigation guidance according to HDG knob)
Autopilot, Flight Director, Autothrust:

THRUST LEVERS ................................................ FLX OR TOGA
BRAKES ........................................................... RELEASE

Vertical and Lateral Guidance

Vertical and lateral guidance are only shown via Flight Director, as we have not turned on the Autopilot yet and need to be followed manually by the pilot.

Keep the aircraft on the center line while accelerating down the runway.

PRIMARY FLIGHT DISPLAY and ENGINE indications ....................... SCAN

V-Speeds

There are three important speeds for takeoff, which we have configured earlier when programming the MCDU's PERF page for takeoff. These are shown on the PFD's speed tape.

V₁: The speed beyond which takeoff should no longer be aborted. V₁ is depicted as a cyan "1" next to the speedband in the PFD.

V_R: Rotation speed. The speed at which the pilot begins to apply control inputs to cause the aircraft nose to pitch up, after which it will leave the ground. V_R is depicted as a cyan circle next to the speedband in the PFD.

V₂: Takeoff safety speed. The speed at which the aircraft may safely climb with one engine inoperative. V₂ is depicted by a magenta triangle next to the speedband in the PFD.

On a long enough runway, V₁ (depicted by "1") and V_R (depicted by "o") are often very close together and can't be clearly distinguished on the PFD speed tape.

At about 80 knots, slowly release the forward pressure on the sidestick until about 100 knots, when the sidestick should be in the neutral position.
The throttle hand remains on the thrust levers until reaching V₁ to be able to quickly abort the start. Remove the hand from the thrust levers at V₁ to avoid accidentally aborting after V₁.
At V_R apply smooth positive backward stick movement on the sidestick and aim for a rotation rate (pitch rate) of 3 deg/sec for about 5 seconds (15° - 18° pitch attitude). Once airborne, follow the flight director's guidance for pitch attitude.
Tip: Count one-one thousand, two-one-thousand, etc. and hit 15 degrees at five-one-thousand - practice this.

V1 ............................................................... MONITOR
VR ............................................................... PERFORM

Once we have confirmed "positive climb" we retract the landing gear.

LANDING GEAR ...........................................................UP
AUTOPILOT .................................................... AS REQUIRED

.

We confirm that the landing gear is up by looking at the landing gear annunciators, and the lower ECAM Wheels page.

TODO: update screenshot with new gear indicators

TODO: update screenshot with new lower ECAM

This concludes Takeoff.

3. Initial Climb

Situation:

Aircraft has left the ground and is climbing at about 15°.

LANDING GEAR ...........................................................UP
THRUST LEVERS .............................................FLX MCT OR TOGA
FLAPS ..................................................................TO

After Takeoff

After takeoff, the aircraft will use FLX/MCT or TO GA thrust until thrust reduction altitude is reached (typically ~ 1500 ft above runway, this is part of the MCDU setup)

After reaching thrust reduction altitude, the PFD FMA now shows a flashing LVR CLB message to instruct the pilot to move thrust levers to the CL detent.

Pull the throttle back into the CL detent.

TODO: update screenshot with new throttle quadrant

THRUST LEVERS ......................................................... CL
PACKS 1 AND 2 (IF APPLICABLE) ......................................... ON

Autothrust

This activates the Autothrust system (FMA shows A/THR in white now). In the A380 (and most Airbus models) we will not touch the thrust levers again before final approach and landing (under normal flight conditions).

The aircraft will now climb to the altitude selected in the FCU (in our case, 5.000ft).

Activate the Autopilot at this point by pressing the AP1 button on the FCU.

AUTOPILOT .................................................... AS REQUIRED

TODO: update screenshot with new FCU

The FMA now shows AP1 in white in the upper-right corner.

FCU Autopilot Controls

The FCU (Flight Control Unit) shows three important values:

SPD "---" : means the Autopilot is in Managed Speed mode (e.g., 250 kt < 10 000 ft, 290 kt above). If we pull the SPD knob we can select a speed which the Autopilot will then apply.
HDG "---" : means the lateral navigation is in Managed HDG Mode and the Autopilot follows the planned route. Dialing the HDG knob will let us select a heading and by pulling the knob we tell the Autopilot to fly this heading (Selected Heading Mode).
ALT "5000" : means the selected altitude is 5000 ft

At F speed:

FLAPS 1 .............................................................. SET

At S speed:

FLAPS ZERO ........................................................... SET

When reaching S-speed retract flaps.
S-speed is signified with an S next to the speed band in the PFD.

Flaps during takeoff and climb

Depending on the start configuration, there will be different markers next to the speedband in the PFD to show when to retract flaps:

CONF-2 (Flaps position 2): At "F" and positive speed trend
CONF-1+F (Flaps position 1): At "S" and positive speed trend

We always retract flaps by only one step at a time. So, when we took off with FLAPS 2 (CONF-2) we retract FLAPS at "F" to FLAPS 1. Then at "S" we retract them to FLAPS 0.

The TAXI and RWY TURN OFF lights are automatically switched off when the landing gear is retracted. The flight crew should still move the switches to the OFF position as part of after take off flows.

TAXI LIGHT ........................................................... OFF
RWY TURN OFF ......................................................... OFF

What and Why

We do this in case the auto-turn-off has failed. This would mean the lights sitting on the front gear, which are now within the gear housing, will start increasing in temperature.

TODO: update screenshot with new lighting panel

Lastly, we disarm the SPEED BRAKE and turn on the PACKS if we turned them off for takeoff.

TODO: can we remove this part if we have the checklist items below?

SPEED BRAKE ....................................................... DISARM

Now complete the "After takeoff checklist"

PACKS 1 & 2 ........................................................... ON
FLAPS .......................................................... RETRACTED
BARO SETTING ........................................................CHECK

Check Baro setting: above transition altitude (defined in the ECAM PERF page) set it to STD by pulling the baro knob. A flashing baro value in the PFD will remind us in case we forgot.

TODO: update screenshot with new checklist if different

AUXILIARY POWER UNIT BLEED ........................................... OFF
AUXILIARY POWER UNIT MASTER SWITCH ................................... OFF
TA MODE ............................................................ TA/RA

This is usually a good time to contact ATC Departure to check in with your current altitude. In most cases, ATC will now give us a higher climb altitude. If we did not receive a higher altitude, we have to level off at the previously cleared altitude (cleared by ATC or navigational charts). If we have the Autopilot activated, it will level off automatically at the Selected Altitude.

This concludes the Initial Climb.

4. Climb

Situation:

Aircraft is climbing to or is at our initially cleared climb altitude.
After takeoff checklist is completed.
ATC has given us clearance for further climb.

CRUISE FLIGHT LEVEL ...................................... SET AS REQUIRED
CLIMB SPEED MODIFICATIONS .................................... AS REQUIRED

Dial the newly cleared altitude into the FCU. (e.g., 15 000 ft) and push for managed climb (CLB) or pull for open climb (OP CLB)

TODO: update screenshot with new FCU

ANTI-ICE ..................................................... AS REQUIRED

The aircraft will now continue climbing while managing thrust and pitch level. The Autopilot ensures that the aircraft stays at the Selected or Managed Speed setting and climbs to the new altitude while managing thrust automatically.

The PFD's FMA now shows:

THRUST LEVER ...................................................... THR CL

Typically, the climb to the flight plan's cruise level (e.g., FL210) happens in several steps (step climbs). Each to be instructed and cleared by ATC.

Using V/S

It is not recommended to use V/S for climbing or descending in the A320 (at least not for beginners) as the V/S guidance has priority over the speed guidance, and speed needs to be watched very closely when using V/S.

If the selected target V/S is too high (relative to the current thrust condition and speed), the FMGC will steer the aircraft to the target V/S, but the aircraft will also accelerate or decelerate. When the speed reaches its authorized limit, V/S automatically decreases to maintain the minimum or maximum speed limit.

5. Cruise

Situation:

Aircraft has leveled off at planned cruise level.
Speed is cruise speed as per ECAM PERF CRZ page.

ALT CRZ on flight annunciator mode ................................. CHECK
ECAM MEMO ......................................................... REVIEW
SD PAGES .......................................................... REVIEW
FLIGHT PROGRESS .................................................... CHECK

This is usually the quietest time of the flight. It allows time to double-check the systems by going through all ECAM pages, etc. Regular ATC frequency changes with altitude and position check-ins are common.

Here are some typical activities which might happen during cruise mostly on request from ATC or other circumstances like weather, traffic, etc.

Altitude Change

Altitude change (also called flight level change)
Like before, during climb, set your new altitude in the FCU and push the ALT knob. The aircraft will descent or climb to the new altitude automatically.

Course Change w/Selected Heading

Course change with Selected Heading (given or cleared by ATC)
Dial heading knob to the desired heading and pull knob for Selected Heading Mode. The aircraft will automatically change course to the new heading. If you want the aircraft to follow the planned route again, you can push the knob for Managed Heading Mode.

DIR TO

Direct course to a waypoint (DIR TO)
ATC regularly instructs us to go "direct to (waypoint) XYZ". Use the ECAM DIR page to select the waypoint from the flight plan's list of waypoints. In rare cases it is a waypoint not in the current flight plan, then you can enter a new waypoint in the MCDU and put it into the upper left entry field. Select DIRECT* on the right-bottom to execute the change.

TODO: update screenshot with new ECAM

ATC requests specific speed

ATC requests specific speed
Sometimes ATC requests a specific speed to keep separation between aircraft. Pull the speed knob to switch to Selected Speed Mode. The current speed will be preselected. Dial to the desired speed. The aircraft will immediately begin to target the new speed by either increasing or decreasing thrust.

At some point (200 - 300 NM from destination) we would start with descent-planning and setting up the aircraft for descent and approach.

Descent, Approach, and Landing will be covered in later chapters of this beginner guide.

This concludes the Cruise.
