A320 OEI Max Accel Alt

[MD83FO]

Hello, wondering where I can find or weather someone has a table for engine out maximum accelerarion altitude for A320 CFM variant.
Thanks.

I do not think there is one, but I had been wrong before. In the days of non-LPC performace courses, you could would find the value on the RTOWs, calculated from PEP. Maybe there is a way to produce such tabelated data from the PEP itself, but for that we'd need a properly trained preformance engineer to answer.

Hope it's not too nosey, what would be a use case for such table?

regards, FD.

At previous job, in the absence of plate 10-7 we had a flow chart for one engine inoperative missed approch ( which I'd post if I knew how), where if the MSA and/or Missed approach altitude fell below EO maximum level off altitude, that lower altitude would become your acceleration altitude for EO missed approach, and published missed approach flown.
otherwise the EOSID should be flown.

The chart I have is for QR IAE,
now with new LCC there is lack of guidance on this subject and we use CFM.

We had such data in paper RTOW charts,but now my company uses EFB
Safe flights

I think it's not quite the case to mix a Max acc alt from RTOW Chart and EO missed app acc altitude. Of course, it's a very safe altitude, but it has entirely other criteria.
I have not found any tool in PEP to produce the tabulated data, too many entries

Max Acceleration altitude is actually displayed on airbus EFB software. It just doesn't say it is for OEI.

would it just be the altitude that you can reach with max thrust on 1 engine until you reach the specified time limit where you then have to decrease to MCT

[FlightDetent]

R36: not really. MAX OEI ACC ALT is limited by the permissible TO-THRUST time (10 minutes usually). Within this time frame, you must not only reach the ACC ALT, but also clean up to Vzf and establish to 4 segment climb.

OEI ACC ALT max displayed for takeoff performance accounts for the take-off roll, EF at the pre-determined point on runway, SE climb and level acceleration. Anvaldra remarks wisely, that applicability for G/A OEI is debatable.

MD: You are indeed trying hard to crack that OEI G/A issue! Personally I gave up some time ago and in the absence of company guidance just ask the examiner beforehand. What is a 10-7 page?

regards, FD.

As rightly pointed out MAX ACC ALTITUDE is ten minutes limited after T/O acceleration altitude. It is given at the bottom of the RTOW chart. It is not related to Missed Approach ACC Altitude as the point at which MA is initiated and at which the a/c gets airborne on T/O are not same. More over MA procedure and departure procedure may be different. Some airlines use missed MA ALT as acceleration altitude. However if the MA is high then airbus recommends to find out if acceleration is possible before the MA ALT. This is airline's job and it is not specified by the authority.

What is a 10-7 page?

My guess is a tailored Jeppesen page for the carrier's OEI procedure.
