Hi there,
you can also look in the RCA (Reglamento de la Circulación Aérea), the spanish law for air traffic. In the 4th Book, Chapter 10 you will find a complete list of phrases along with it´s equivalent in english. You will also find some phrases in other chapters, but I warn you it´s a huge document (nearly 700p) regarding almost every aspect involved in air transportation.
