1.2. Course Objectives
− The main objective of this course is to present the AIRBUS performance documentation:
• Flight Crew Operating Manual, FCOM.
− To do so, the following will be reviewed:
• Basic regulations,
• Aircraft performance.
− By the end of this course, you will know:
• What kind of information you can get in the AIRBUS documentation,
• Where to find this information,
• How to use the information.
− More particularly, you will know:
• How to determine the Max. TOW and the corresponding speeds,
• How to determine the "Flexible Temperature" (or assumed temperature).

GUIDED EXAMPLES
6.1. Example 1: MTOW
PURPOSE
What is the maximum permissible takeoff weight and associated speeds?
LFPO ATIS
AIRCRAFT STATUS: A320-214
Provides the following data:
MTOW Structure: 75.5 T
Takeoff runway
: 08
Takeoff Configuration: Optimum
Runway condition
: DRY
Air conditioning : ON
Wind calm
Total Anti-ice
Temperature
: 51°C
QNH
: 1003 hPA
: OFF
Step 1 - Refer to RTOW
Enter the table Wind 0 / Temperature 51°C.
Read 74 200 kg for Conf 1 + F, 74 100 kg for Conf 2, and 74 100 kg for Conf 3.
Step 2 - Corrections – Influence of delta pressure
∆ QNH : -10 hPA.
Read (-0.8 T) for Conf 1+F, Conf 2 and Conf 3.
Read (∆V1 = 0, ∆VR = 0, ∆V2 = 0) for Conf 1+F, Conf 2 and Conf 3.
Step 3 - Correct the weights
Conf 1 + F 74 200 - 800 = 73 400 kg.
Conf 2 74 100 - 800 = 73 300 kg.
Conf 3 72 700 - 800 = 73 300 kg.
Step 4 – Find the speeds
Conf 1 + F
73 400 kg.
V1 = 156 - 0 = 156 kt, VR = 156 - 0 = 156 kt, V2 = 157 - 0 = 157 kt.
Answer
MTOW = 73 400 kg in configuration 1 + F.
Speeds: 156 - 156 - 157.

Step 1 - Refer to RTOW
Enter the table Wind 0 / Temperature 51°C.
Read (74.2 156/56/57) for Conf 1+F; (74.1 152/52/56) for Conf 2; and (74.1 152/52/55) for Conf 3.
Step 2 - Corrections – Influence of runway condition
WET:
(-0.6 T, ∆V1 = -6, ∆VR = -2, ∆V2 = -2) for Conf 1+F,
(-0.4 T, ∆V1 = -3, ∆VR = 0, ∆V2 = 0) for Conf 2,
(-0.2 T, ∆V1 = -3, ∆VR = 0, ∆V2 = 0) for Conf 3.
Step 3 - Corrections – Influence of delta pressure
∆ QNH : -10 hPA.
Read (-0.8 T) for Conf 1+F, Conf 2 and Conf 3.
Read (∆V1 = 0, ∆VR = 0, ∆V2 = 0) for Conf 1+F, Conf 2 and Conf 3.
Step 4 – Total corrections
∆ WET + ∆ QNH
Conf 1+F ∆W=-600-800=-1400
∆V1= -6-0=-6
DATE: SEP 2006
Conf 2: ∆W=-400-800=-1200

Answer
MTOW = 73 100 kg in configuration 3
V1 = 149 kt, Vr = 152 kt, V2 = 155 kt
NOTE:
As two corrections are applied, speeds must be checked against minimum speeds (first on RTOW and secondly in FCOM

Provides the following data:
MTOW Structure: 75.5 T
Takeoff runway
: 08
Takeoff Configuration: Optimum
Runway condition
: WET
Air conditioning : ON
Wind calm
Total Anti-ice
Temperature
: 3°C

Step 1 - Refer to RTOW
Enter the table Wind 0 / Temperature 3°C.
Read (81.9 161/61/63) for Conf 1+F; (81.9 159/59/64) for Conf 2; and (82.0 159/59/61) for Conf 3.
Step 2 - Corrections for Total Anti-ice- Refer to 2.02.14 p 1
OAT<=ISA+5: subtract 950 kg
Step 3 - Refer to RTOW, find new speeds with the corrected weight.
Conf 1+F: 81.9-0.95=80.95 T

Step 1 - Detemination of pressure Altitude - Refer to 3.05.05 p 3
Enter the table with QNH = 989
Read correction of + 700 ft
Add this correction to the airport elevation: 700 + 276 = 976 ft
Step 2 - Determination of corrected Runway - Refer to 2.02.40 p 2
Enter the table with Runway length = 3 500 m and read correction for the slope: 600 m per percent
Corrected Runway length = 3 320 - 600 * 0.1 = 3 260 m
Step 3 - Find MTOW- Refer to 2.02.40 p 5
Enter table with 3250 / 20°C
Read MTOW = 81 200 kg
Step 4 - Corrections for air conditioning - Refer to 2.02.24 p 1
Air conditioning: - 2 200 kg
MTOW = 81 200 - 2 200 = 79 000 kg

Obstacle height = 62 + ( 0.07 * 50 ) = 66 ft (correction due to the slope)
Obstacle distance from end of runway = 3 764 - 3 320 = 444 m
Weight decrement = 9.0 t

You need less Thrust
When your Actual TakeOff Weight is lower than the Maximum TakeOff Weight, you can perform a TakeOff with less than
the max TakeOff thrust.
This thrust reduction improves engine life and reduces maintenance costs.

Short runway: TOGA is used & V1 min is high
V2
V1=VMCG
VR
35ft
ACC STOP
This is due to excess of thrust
The present take off weight is VMCG limited, because of a short ASD and a high V1 min.
We can observe a large excess of thrust after lift off.
This excess of performance (thrust) is penalizing on ground and not necessary after lift off.
V1=VMCG
VR

ACC STOP
If, for the same TO weight, the maximum TO thrust is reduced or derated by a given percentage of X%, the
associated VMCG is decreased.
Consequently:
–
V1 may be reduced,
–
ACC/STOP distance is decreased accordingly,
–
climb out performance may still be met.
Thus derated take off may allow to increase TO weight

The Derated TO thrust is therefore to be considered as the maximum TO thrust rating available for a given take off.
It determines the new VMCG and the new VMCA applicable during that take off.
The use of Derated take off thrust:
•
increases payloads when operating on:
- short runways,
- contaminated runways.
•
also saves engine life.
Each derate level is certified and is associated to a new set of performance data

Principle
Advantages of derated take off :
•
•
TOGA Thrust
significant reduction of engine stress (like Flex TO),
decreasing TOGA will also decrease VMCG, and
the available value of V1, which enables short TO,
allowed on contaminated Runways.
•

The original TOGA will never be available during TO.
Flexible thrust
Derated thrust
• Thrust level is less than TOGA
• Thrust level is less than TOGA
• Performance for a flex Take-Off is computed by
adjusting the max Take-Off thrust performance.
• A new set of performance data is provided in the
Flight Manual for each derate level.
• At any moment it is possible to recover TOGA.
• TOGA selection is not possible during Take-Off.
• Thrust setting parameters for flex Take-Off are not
considered as Take-Off operating limits.
• Thrust setting parameters are considered as an
operating limit for Take-Off.
• Flex Take-Off cannot be performed on contaminated
runways.
• Derated Take-Off is allowed on contaminated
runways.

8.2. Dispach Requirements
8.2.1. Required Landing Distance
In all cases, and for both regulations ( JAR and FAR ),
the requirement is:
RLD ≤ LDA
On Dry Runways:
RLD dry = ALD / 0.6 ≤ LDA
On Wet Runways:
RLD wet = 1.15 RLD dry ≤ LDA
On Contaminated Runways (JAR-OPS operators only):
ALD contaminated x 1.15
≤ LDA
RLD contaminated = the greatest of
RLD
For contaminated runways, the manufacturer must provide landing performance data and
detailed instructions about the use of antiskid, reverse, airbrake or spoilers.

JAR
The safety margin remains at the Captain’s discretion.
FAR
ALD x coefficient (system failure) x 1.15 ≤ LDA
The 1.15 factor is not requested in case of emergency (to be evaluated by the flight
crew).
« NEW RULE » ( Safety Alert For operators from 31st Aug 2006 )
ALD must account for:
- Pressure altitude
- Wind
- Surface condition (dry, wet or contaminated)
- Approach speed
- Landing weight & configuration
- Planned use of airplane ground deceleration devices (brakes, spoilers, antiskid, reversers)
