FMC Navigation

Question 1

In order for LNAV to arm on the ground, the departure runway must be entered with a course to the first waypoint within ___ deg. of runway heading

Answer 1

5 deg.

Question 2

After rotation the pitch commands ___ deg. nose up until sufficient climb rate is achieved.

What speed is then maintained?

Answer 2

15 deg.

V2+20

Question 3

V2+20 is maintained after takeoff until when?

Answer 3

Bug up speed, usually 1000 ft AGL

Question 4

If an engine failure occurs on takeoff the commanded speed will depend on the actual speed at the time of the failure.

Explain how the A/c selects a speed.

Answer 4

For failures at or below V2, the commanded speed will be V2.

For failures between V2 and V2 plus 20, the commanded speed will be the failure speed.

For failures at V2 plus 20 or greater, the commanded speed will be V2 plus 20.
