In Minnesota, brown trout 250-380 mm (10-15 in) long and 1.6-2.5 kg (3.5-5.5 lbs) are fairly common in streams. Stream browns over 635-mm (25-in.) long and 5.5 kg (12 lbs) are rare, but in Lake Superior they are often bigger. The Minnesota state record for this fish is 7.56 kg (16-lbs. 12 oz).
Since jets take off at a particular airspeed, the ground speed they need depends on the prevailing winds. Suffice it to say, a 737 rotates at an airspeed of around 130 to 150 knots, depending on weight (among other factors), and an A380 rotates somewhere around 140 to 180 knots.
Airspeed is measured with respect to the velocity of the object through the air. The average cruising speed is between 550 and 580 mph. Wind resistance is a key factor when determining the speed of the aircraft. The average landing speed for a commercial jet is 150 to 166 mph. Changes in speed can be a result of weather conditions, runway length and landing weight.
