CRZ OPT REC MAX (Line 1)

CRZ: Cruise altitude or FL as entered in

the ACTIVE F-PLN.

OPT: Optimum altitude is the altitude for

minimum cost.

Computation takes into account: CI (cost

index) corrected by Perf Factor, Ground

Speed (KT), total fuel flow.

REC MAX: Recommended Maximum

Altitude computed according to following

criteria:
