Which condition increases the takeoff distance required?

Choices

  • ✓ High density altitudecorrect

    High density altitude reduces performance and lengthens the takeoff roll.

  • A strong headwind

    A headwind shortens the takeoff distance.

  • A downslope runway

    A downslope generally shortens the takeoff run.

  • Lower aircraft weight

    Lower weight shortens, not lengthens, the takeoff distance.

Why

High density altitude, a tailwind, an upslope, or a soft/wet surface all lengthen the takeoff distance; a headwind and lower weight shorten it.
