A tailwind increases the object's speed and reduces the time required to reach its destination, while a headwind has the opposite effect. The terms are also used metaphorically in business and elsewhere about circumstances where progress is made harder (headwind) or easier (tailwind).
For example, a 10 knot wind coming at 45 degrees from either side will have a crosswind component of 10 knots × sin(45°) and a head/tailwind component of 10 knots × cos(45°), both equals to 7.07 knots. Pilots can use a use a crosswind component chart to calculate the headwind component and the crosswind component.
This new airspeed will be faster as the headwind increases, but will result in the greatest distance covered. A general rule of thumb is to add half the headwind component to the best L/D for the maximum distance. For a tailwind, the origin is shifted to the left by the speed of the tailwind, and drawing a new tangent line.
"So there is a very strong tailwind."Unknown HeadwindDespite a clear tailwind, Slack also faces a headwind that's difficult to quantify. During the current difficult environment highlighted by ...
The flight time will depend on both the desired cruising speed of the aircraft, and the wind – a tailwind will shorten flight times, a headwind will increase them. The flight computer has scales to help pilots compute these easily.

[1] [2] For example, a descent from flight level 350 would require approximately 35x3=105 nautical miles. This would have to be adjusted for headwind or tailwind, [1] and also to allow for deceleration time. Alternatively, David P. Davies gives the rule as 300 feet of descent required for each nautical mile of distance. [3]: 176
