                         improving our knowledge about dynamics in the Mesosphere and Lower 
                         Thermosphere (MLT) region. However, instrumental limitations 
                         hinder its use for measuring the vertical winds and momentum 
                         fluxes. According to Babu et al. (2012) all-sky meteor radars are 
                         able to infer vertical wind when using a large number of meteor 
                         echoes centered at the meteor ablation peak. On the other hand, 
                         simpler all-sky meteor radars can not reach this condition, 
                         leading low confidence on its results. In order to evaluate the 
                         accuracy of vertical winds values we have performed several tests 
                         based on a simple model considering real meteor distributions and 
                         theoretical equations of MLT winds motion. Moreover, we have also 
                         considered a random error simulating instrumental measurements 
                         errors on radial velocities. As a result of our tests, Brazilian 
                         SKYiMETs radars data can be used for this purpose with an accuracy 
                         of ~ 1 m/s, what means that we can not measure weaker flows. This 
                         is reasonable once planetary scale waves, like Kelvin waves, can 
                         reach vertical winds around 4 m/s, and also gravity waves can 
                         reach values even larger as 20 m/s. Furthermore, we could recover 
                         very well the period of about 3.5 days for Kelvin Wave. These 
                         results are important since they support the use of meteor radars
