"Aptitude test" that is always performed in pilot tests of pilots, especially the Self-Defense Forces.It is a training app to improve the ability to instantly answer the model direction of an airplane.Even if it is "appropriate", it is not only the one that was born, but in order to make a difference by practicing and to make the high-magnification exam even a little more advantageous, it is necessary to train on a daily basis. its important.An app that can be used not only as a pilot but also as a brain trainer.There are 3 levels of difficulty.Easy: EasyEither North (N) East (E) South (S) West (W) is shown at a random position.The heading (fixed upward) at that time will be answered within 10 seconds.Normal: Normal:In addition to Easy mode, one of the intermediate directions northeast (NE), southeast (SE), southwest (SW), and northwest (NW) is shown at a random position.The heading (fixed upward) at that time will be answered within 10 seconds.Hard:From the orientation shown in the same way as Normal, the model orientation (direction is random) will be answered within 7 seconds.Its a very simple app, but I made it with the hope that it will be of some help to anyone who wants to become a pilot.We plan to update it in a timely manner.
