GENERAL
Applicable to:
, ,
MSN
This following information is issued to permit the CFM 56-5-B SAC (Single Annular Combustor) and
CFM 56-5-B DAC (Double Annular Combustor) engines to be intermixed.
ENGINE PARAMETERS
Applicable to:
, ,
MSN
Engine parameters differ significantly, when the engines are at idle :
EGT : Up to 250 °C higher on the DAC
FUEL FLOW : Up to 25 % higher on the DAC
N1 : Higher on the DAC
N2 : Lower on ground on the DAC ; higher in flight on the DAC
CROSSBLEED ENG START
Applicable to:
, ,
MSN
The DAC engine has insufficient acceleration capability to sustain idle speed with a large bleed off
take, when it operates with only 20 injectors. Therefore, it is necessary to preset a 30 % N1 on the
supplying engine before lauching the start sequence.

TAKEOFF PROCEDURE
Applicable to:
, ,
MSN
The PF has to progressively adjust ‐ engine thrust in two steps :
• Step 1 : Idle to 50 % N1
Brakes released, when the 50 % N1 is stabilized on both engines.
• Step 2 : Both engines N1 to takeoff thrust.
This procedure permits a significantly slower acceleration from ground idle to
N1 = 50 % for the double annular combustor.
‐ Other standard operating procedures apply for takeoff.
ENGINE RESPONSE
Applicable to:
, ,
MSN
In flight, when the aircraft is in clean configuration, the DAC engine may accelerate from idle more
slowly than the SAC engine. This is particularly evident, if the acceleration follows a deceleration.
There is not a significant effect on aircraft handling. This difference in engine response disappears
when the slats are extended.
ENGINE RELIGHT
Applicable to:
, ,
MSN
DAC engine relight envelope is more restrictive than the SAC engine relight envelope.
Therefore, in case of engine intermix, the DAC engine relight procedure must be used with the
corresponding chart (See chart below).
