Answer 4

Reversers considered. TOGA. Screen height 15ft. RTOW must not exceed that of a dry runway

Question 5

TO FLEX

Answer 5

A319: 75 (ISA+60) to OAT/45 (ISA+30) A320: 69 (ISA+53) to OAT/44 (ISA+29) EAI: -5. QNH: -1

Question 6

Question 8

V2

Answer 8

VS1G x1.13. Min: VMC x1.1/VS1G x1.13. Achieved before screen height. Slower would not give required climb gradient
