Geocache Description:

Do NOT even try to go at posted coordinates, it is the airport zone! Solve the mystery to get the real coordinates.

About the airport:


IATA (International Air Transport Association airport code) – VNO. The characters prominently displayed on baggage tags attached at airport check-in desks are an example of a way these codes are used.

ICAO (International Civil Aviation Organization airport code) - EYVI. The ICAO code is used by pilots and air traffic control. In general IATA codes are usually derived from the name of the airport or the city it serves, while ICAO codes are distributed by region and country. EYVI – last two characters represent Vilnius, EYKA – Kaunas, EYPA – Palanga.



About the mystery cache:


This mystery is based on Vilnius airport and its territory. You will discover it in more detail. So, the task consists of 2 parts – East and North. “East part” will help to get the final geocache East coordinate, while “North part” – final North coordinate. Many answers to the questions can be found on the internet, but some require additional information available in PDF format below. Also, check out the useful links.
*Alert: You are about to download several files that contain further details needed to find this geocache. As the cache owner, I represent that these files are safe to download although it has not been checked by Groundspeak or by the reviewer for possible malicious content.

East Part


1. [altitude]


The main runway of Vilnius airport is not ideally horizontal. The beginning and the end are situated at different altitudes. Find the difference between those altitudes (use feet, not meters). This will be your number [altitude].

2. [crash]


In 2007 Vilnius airport encountered an accident. A two-motor aircraft reported having problems with the landing gear. The right gear collapsed after touchdown (see photo). The right wing and the fuselage were damaged. No people were seriously injured. Name the model of the aircraft. Take the DIGITS (not numbers) from the model and sum the digits. This will be [crash]. (Example: if a model is a Boeing 737-300, you should do: 7+3+7+3+0+0=20. Number for [crash] would be 20.)



3. [video]


The video is taken from the passenger's seat. This is a pre-flight procedure usually done in winter. At what stands this procedure can be made in Vilnius airport? Sum the stands numbers. This will be [video]. (Example: if the procedure is done at stands 1, 10, 20, then [video]=1+10+20=31.)

***Video***

4. [fire]


This is a model of the aircraft used for firefighters training. Find it on the map. Use the most recent map data, not the old ones. Take 1 digit before the point and 1 digit after the point from the East coordinate of the aircraft. Sum of two digits. This will be [fire]. (Example: E 025 56.789. You should take 6 and 7. Sum: 6+7=13)



5. [pressure]


This is one of the taxiways from the runway. Find out what maximum tire pressure this taxiway can support (units - psi). This will be [pressure]

UPDATE: the wikipedia article about taxiway pressure values has been changed. Use the old data from an earlier version of the page: Wikipedia OLD



6. [radar]


Here you can see an actual photo of one of the several radars in Vilnius airport. How this radar is called? Answer should contain 3 letters. Convert the letters into numbers and sum them. This will be [radar] Use this tool to convert easily
(Example: GEO will be converted into 7, 5 and 15. 7+5+15=27. Final number is 27.)




7. [landing]


You are about to land in Vilnius on runway 02. To land successfully you should land on the runway at a specific angle of approach. On the photo the PAPI (Precision approach path indicator, marked as red circles) shows if you are above, below or at optimum glide slope. How many white lights (in one red circle, doesn't matter left or right) should you see for an optimum approach angle? This will be [landing].



North Part


Now you will hear a recorded audio file with the real ATC (air traffic controller) and pilot communication. Your task is to find the airline call sign numbers from the communication. The list of airlines is present below.

Ryanair 1
airBaltic 1
Air Lituanica 1
Lufthansa
Scandinavian
Ryanair 2
Transavia (should be Transaero)
Small Planet Airlines
Air Lituanica 2
airBaltic 2

Usually a call sign consists of the airline name + some numbers (sometimes numbers with letters). For example, "Geocaching Airlines 63" or "Geocache Air 357MT". If a callsign has letters in it, just ignore those letters. Example: from the airline "Geocaching Airlines 63" take 63 and from "Geocache Air 357MT" take number 357.

Final coords


Final coordinates can be calculated by formula or by using this Excel sheet (the lazy way;) )
Final formula for coordinates:

N 54 38 .
(Air Lituanica 1 + Air Lituanica 2) – (Ryanair 1 + Ryanair 2) – Small Planet Airlines + Lufthansa + (airBaltic1 + airBaltic2) – Scandinavian + Transavia + 12

E 025 16 .
( [altitude] + [crash] + ([video] * 2) + [fire] + [pressure] + [radar] + [landing] – ([crash] / 3) )
