Question 1

What is Rec Max Alt and Optimum Alt?

Answer 1

REC MAX is max altitude that can be flown at current weight and temperature to provide a 0.3g margin against buffet
With CLB it provides min 300fpm

OPT based on current weight, CI, temp and winds. Most efficient cruise altitude

Question 2

What is ‘optimum speed’

Answer 2

Changes depending on flight phase. Most efficient speed for that manoeuvre

Question 3

What are turbulence penetration speeds?

Answer 3

Below FL200 = 250kts
Above FL200 = 275kts
Mach 0.67
