Hello, How fast can a real 737-800 fly? In Flight Simulator X, you're only aloud to go 340 knots then the overspeed alarm comes on. And I know that when I fly on a 737 we're easily going 450 knots.n Flight Simulator X, you&#39;re only aloud to go 340 knots then the overspeed alarm comes on.

Dorsiflexion of the foot uses four muscles. These are the tibialis  anterior, extensor digitorum longus, extensor hallucis longus, and  the peroneus tertius.orsiflexion of the foot uses four muscles. These are the tibialis  anterior, extensor digitorum longus, extensor hallucis longus, and  the peroneus tertius.
However, many muscles that power the footâs movement originate as high up as the back of the knee. Some important muscles that affect the foot include: 1  Soleus: This muscle extends from the back of the knee to the heel. 2  It is pivotal in walking and standing.3  Gastrocnemius (calf muscle) : One of the large muscles of the leg, it connects to the heel. 4  It flexes and extends the foot, ankle, and knee.he muscles are attached to bone by fibrous tendons. In terms of mobility, the Achilles tendon is one of the most important structures in the leg and foot. This tendon in the back of the calf and ankle connects the plantaris, calf, and soleus muscles to the heel bone.
