Assumed temperature take-off charts

From PMDG Ops

Below data is for the 747-400 aircraft.

Please read carefully the explanation how to use the table further below in the main body of the text and then you can follow the example right below.

Example: Your TOW is 395000 KG and you are taking off from runway 09L (or 09R) at London-Heathrow then using the very first table you find the next highest weight for runway 09L (397100 KG) and right next to it you find assumed temperature of 40C. However we also have to cross over to the right portion of the table which shows climb-limited data and in this case we are limited even more since our TOW is below the value of 399400 which corresponds to derate of 34C. So ultimately our allowed derate is 34C (and not 40C) and the V1/VR/V2 are right next to it: 155/171/181. You always have to select the most limiting of the two cases - field or climb.

Please note that with the wind you will be adding weight correction for the tailwind and subtracting for the headwind.

2.8 REDUCED TAKE-OFF THRUST "ASSUMED TEMPERATURE" METHOD 

2.8.1. Assumed Temperature Take-off Thrust may be used at the Captain's discretion. It is expected 
however, that Captains will normally make use of this procedure unless prohibited by any of the 
exceptions given below. Use of reduced thrust, where possible, will benefit engine life and make a 
significant contribution to reducing the rate of engine failure. A 'buffer' on performance is contained 
within this method as the true airspeed at the actual temperature is always less than it is at the 
assumed temperature used. 

2.8.2. Assumed Temperature Take-off Thrust must NOT be used when : 
(a) The Runway is affected by snow, slush, standing water or ice, or suspected of having a 
marginal braking capability. A de-rated thrust setting (TO-1 or TO-2) may be published for a 
CONTAMINATED runway RTOW page. 
(b) The individual RTOW table specifically prohibits such use. 
(c) Significant windshear conditions are anticipated. 
(d) Operating with landing gear extended. 
(e) One or more anti-skid channels are inoperative. 

2.8.3. PROCEDURE 
To obtain reduced take-off thrust N1%, complete the normal RTOW calculation form using forecast 
conditions and apply the necessary corrections. Determine the 'ASSUMED WEIGHT' by reversing the 
sign of the 'Total Corrections' and applying this figure to ACTUAL take-off weight. 
Enter the Runway column of the RTOW page for the appropriate runway with the ASSUMED 
WEIGHT and work down from the top of the column until reaching a weight that equals or just 
exceeds the ASSUMED WEIGHT. Ensure that the weight in the CLIMB LIMIT column is higher. If it 
is, note the temperature. 

This is the ASSUMED TEMPERATURE for take-off N1%. If the CLIMB LIMIT weight is lower, cross 
to the CLIMB LIMIT column and continue down until reaching a weight that equals or just exceeds the 
ASSUMED WEIGHT and use the associated temperature as the ASSUMED TEMPERATURE. 
To obtain V1/VR/V2 re-enter the Runway column with the ACTUAL TAKE-OFF WEIGHT and work 
down from the top of the column until reaching a weight that equals or just exceeds ATOW.Ensure 
that the weight in the CLIMB LIMIT column is higher. 

If it is read-off V1/VR/V2 at this point. If the CLIMB LIMIT weight is lower, cross to this column and 
continue down until reaching a weight that equals or just exceeds the ATOW and read-off V1/VR/V2 
at this point. 

2.8.4. Full power may be selected at the Captain's discretion at any time if required. 
The engines will not be over-boosted when maximum thrust is selected.
