Laskeutumisprofiili

Laskeutumisprofiili is a Finnish term that translates to "landing profile" in English. It refers to the planned trajectory and sequence of actions for an aircraft or spacecraft during its descent and landing phase. This profile is crucial for ensuring a safe and controlled landing under various conditions.

The landing profile is typically determined by several factors, including the type of aircraft or spacecraft, its weight, atmospheric conditions, runway or landing site characteristics, and the specific mission objectives. For aircraft, it involves a precise sequence of speed reductions, flap deployments, and control surface adjustments to manage descent rate and airspeed. Air traffic control often plays a role in guiding aircraft onto their respective landing profiles to maintain safe separation.

For spacecraft, the landing profile is significantly more complex due to the extreme speeds and hostile environments involved, such as re-entry into an atmosphere. It may include atmospheric braking, parachute deployment, retro-rocket firing, and finally, touchdown. The accuracy and execution of the landing profile are paramount for mission success and crew safety. Engineers meticulously design and simulate these profiles to account for a wide range of potential scenarios and contingencies.
