The legs are generally described as A) Downwind, B) Base, C) Final, D) Upwind, and E) Crosswind. These are probably the names most widely used. For the purposes of this article, we will be primarily concerned with A, B, and C. We wont get much into the remaining 2 legs, D and E, which are of concern when using a Touch and Go landing or executing a Missed Approach. (NOTE: Although this was indeed our original intent, in the example flight we took to document and further explain the procedures, we ran into the situation of needing to do a Go Around procedure. Therefore, we modified our procedures to include a brief section on Legs D and E.) But the simplified view
above which Microsoft supplied in their manuals probably needs some further
enhancement as follows: Also be aware that at many airports, due to local conditions such as mountains or avoiding the patterns of other nearby airports, the Approach Pattern is totally reversed. In this document, it is depicted as being North of an East/West runway and using left hand turns. A reversed pattern would be South of an East/West runway and using right hand turns. Also, it might be important to note that ATC (Air Traffic Control) may instruct you to enter a Left Pattern or Right Pattern. They are referring to the direction of the turns. The example above and below are the standard and most widely used Left Pattern. What may be particularly confusing is that, if you were to be approaching this runway from 15-20 nautical miles east, then the place to enter a Left Hand Pattern would appear to be to the RIGHT side of the runway: |
