Azores Archipelago is a set of 9 islands, located in the middle of North Atlantic Ocean, and Santa Maria Airport (LPAZ) is one of the airports, located in Santa Maria Island (Ilha de Santa MAria).

The 9 islands are (by area) - airport ICAO code in parentheses : São Miguel(LPPD), Pico(LPPI), Terceira(LPLA), São Jorge(LPSJ), Faial(LPHR), Flores(LPFL), Santa Maria(LPAZ), Graciosa(LPGR) and Corvo(LPCR). To give an idea of dimension, the biggest island is São Miguel (pop. 135.000) has an area of 746 Km2 and the smallest is Corvo (pop. 384) with 17 Km2. All the islands are inhabited, and as you saw above, all of them have an airport.

The biggest airport is in Terceira - Lajes Airport (LPLA) that in fact is a Civil Airport together with an American Militar Base, and it's runway  is the most extensive among the airports of Portugal. Another curious fact about Azores is that the highest point of Portugal is in Pico Island.

To give an idea, a flight between Lisbon or Oporto for Lajes airport is around 2:10 (Airbus A320 as reference).

SATA Group is the Azores aviation company, with flights between islands but also for Portugal Main Land, EUA, Canadá and some other countries in Europe. On their fleet they have A321 / A320 / Bombardier Q400 and Q200 (Bombardier for flights between Azores islands).

About my LPAZ airport changes, please note that doesn't reflect the real airport, are only some additions to try bring more life to it.

I have developed new sceneries for every Azores airport, excluding:

LPPI - Handcrafted by MS/ASOBO in WU8 Spain, Portugal, Andorra and Gibraltar;

LPPD / LPHR - Check the models from slipnoidz (https://flightsim.to/file/8526/lppd-small-terraforming-around-airport) and (https://flightsim.to/file/19213/low-budget-lphr-faial-azores-upgraded-default)

LPLA - Already available in Simmarket;

Then please check my other sceneries of LPSJ (São Jorge Airport), LPCR (Corvo Airport), LPGR (Graciosa Airport), LPFL (Flores Airport), all of them available here on flightsim.to:

São Jorge Airport - https://flightsim.to/file/40790/lpsj-so-jorge-airport-azores-archipelago
Corvo Airport - https://flightsim.to/file/40949/lpcr-corvo-airport-azores-archipelago
Graciosa Airport - https://flightsim.to/file/41864/lpgr-graciosa-airport-azores-archipelago
Flores Airport - https://flightsim.to/file/42024/lpfl-flores-airport-azores-archipelago

All libraries to LPAZ are MSFS standard libraries and you don'ty need to download nothing in addition. 

Please note that I can use different Asobo/MSFS libraries to build my own sceneries, including new libraries from World Updates. Then, if you don't have all World Updates installed on your MSFS, it's possible that you don't see all buildings and other objects from my scenery. It will depend of what objects I have used on each scenery and what World Updates you have or not.

Hope you enjoy my airports, thanks by your support.
