Sheet 2: Notes - Please Read

Row 4	Please mark each column YES or NO to designate whether it contains any confidential business information as such, but only mark that which is truly confidential. Most of the fields will NOT be confidential.
For further information on these reporting requirements, see 40 CFR parts 87.42 and 87.64.
Questions regarding these requirements can be submitted via email to [email protected].
Guidance on specific columns:
Column C:	This is the calendar year for which production is being reported.
Column E:	If engine is turbofan, please indicate if it is mixed flow or not.
Column G:	This is the certificating authority that issued the original certificate for the engine type (e.g., FAA, EASA, TC)
Column H:	This is the date of issuance of the original type certificate for that submodel, not the most recent revision date of the type certificate. Original dates for all submodels are contained in the most recent revision of the type certificate.
Columns R, S, and T:	For purposes of calendar year production, an engine is considered to have been produced on the date shown on its FAA Form 8130-3, "AIRWORTHINESS APPROVAL TAG" or the date shown on the engine identification plate per 14 CFR 45.13(a)(7).
	If a given engine submodel is manufactured by more than one manufacturer or at more than one facility, you may submit the total production of that submodel in a single report.
	If there are no sales of a particular submodel, please enter "0" rather than leaving blank.
Columns U through AL:	Reporting of NOx, HC and CO is not required for engines only subject to a smoke standard.
Columns Y, AE, AK, AW-BB, BT-BY and CJ-CO:	These columns each contain formulas which will calculate the value based on the inputs of their respective preceeding four columns. They are shaded light grey.
Column AQ:	For smoke number, please provide an explanation in the notes column if this value is different than the maximum of the four LTO points.
Column AX-BB:	Carbon dioxide is automatically calcuated: CO2 = fuel_flow*time_in_mode* 3.16
Column BD through CO	Reporting of nvPM is only required for engines with rated thrust greater than 26.7 kilonewtons
Column BT-BY & CJ-CO	nvPM emission rates are calculated: nvPM_corrected = measured_nvPM * nvPM_loss_correction_factor * fuel_flow * time_in_mode
Additional guidance:
Significant Figures:	Please report values consistent with the significant figure requirements contained in 14 CFR 34.23.
Reporting of emission indices at individual LTO operating thrust mode settings are optional, but recommended, for NOx, HC, CO and Smoke.
