84-87%n1

Question 22

What is the B737-8 landing performance data based on?

Opt landing dispatch.

Answer 22

Max manual braking, auto speedbrake, no reverse thrust.

Gives certified landing distance multiplied by 1.67.

Question 23

What data landing data does the QRH/ Fcom1/ opt enroute give?

Answer 23

Landing dist X 1.67 + factored 15% + extended flare (455m) +auto speedbrake and full reverse thrust.
(Except when a non normal is applied no longer factored)
Note: this distance is advisory only but gives the most accurate landing distance)

Question 24

Why are the wet and dry landing factors the same?

Answer 24

The b738 was certified using wet calculations there for any wet distances only have to be factored by 1.67 the same as dry.
