저는 어럼풋이 알고 있길 7000번이 VFR항공기용 코드라고 설명을 했는데, 어떤 분으로부터 7000번대는 비상코드인데 큰일날 사람이라는 얘기를 들었다. 혹시나 내가 잘못알고 있나 싶어 해서 집에 와서 인터넷 검색을 해봤는데, 전세계적으로 7000번을 VFR항공기에 사용하는게 맞는데...
우리나라만 다르게 사용하는가???
물론, 7500이 하이재킹, 7600이 통신두절, 7700이 비상상황인 것은 맞지만, 모든 7000번대가 비상상황을 의미하지는 않는다.
다음은 Wiki에서 검색한 트랜스폰더 코드값이다.
흔히 VFR항공기에 사용하는 1200은 북미지역에서 VFR 항공기에 할당하는 코드라고 한다. 물론, 우리나라 항공법이 주로
미국것을 베끼긴 했으니, 우리나라에서도 1200번대를 주로 VFR 항공기에 사용하고 있겠지만, 7000번이 ICAO에서는
Code를 부여받지 못한 VFR항공기에 부여하는 Squawk Code라고 합니다.
그러니, 북미를 제외한 외국에 나가서 혹시나 트랜스폰더에 7000번 입력되어 있다고 해서 비상코드 잘못 입력했다고 했다가 망신당할 수도 있습니다.
Routine codes

- Shall not be used — is a non-discrete mode A code (Europe)[13]
- 0021: VFR squawk code for German airspace (5000 feet and below) —
from 15 March 2007 replaced by the international 7000 code for VFR
traffic.[14]
- 0022: VFR squawk code for German airspace (above 5000 feet) — from
15 March 2007 replaced by the international 7000 code for VFR traffic.[14]
- 0033: Parachute dropping in progress (UK)[12]
- 0041 to 0057: In Belgium assigned for VFR traffic under Flight Information Services (BXL FIC)
- 0100: In Australia: flights operating at aerodromes (in lieu of
codes 1200, 2000 or 3000 when assigned by ATC or noted in the Enroute
Supplement Australia)[15]
- 1000:
- Instrument Flight Rules (IFR) flight below 18,000' when no other code has been assigned (Canada)[6]
- Non-discrete mode A code reserved use in Mode S radar/ADS-B
environment where the aircraft identification will be used to correlate
the flight plan instead of the mode A code[13]
- 1200:
- Visual flight rules (VFR) flight, this is the standard squawk code used in North American airspace when no other has been assigned.[6]
- In Australia civil VFR flights in class E or G airspace.[15]
- 1202:
- Visual flight rules
(VFR) glider flight, this is the standard squawk code used in United
States airspace for transponder equipped gliders when no other has been
assigned.[16]
- 1400: VFR flight above 12,500'ASL when no other code has been assigned (Canada)[6].
- 2000:
- The code to be squawked when entering a secondary surveillance radar (SSR) area from a non-SSR area used as Uncontrolled IFR flight squawk code in ICAO countries[13]
- In Canada for uncontrolled IFR at or above 18,000'[6]
- In Australia: civil IFR flights in Class G airspace.[15]
- 2100: Australia: Ground testing by aircraft maintenance staff.[15]
- 3000: Australia: Civil flights in classes A, C and D airspace, or IFR flights in Class E airspace.[15]
- 4000:
- Aircraft on a VFR Military Training Route or requiring frequent or rapid changes in altitude (U.S.)[17]
- In Australia: civil flights not involved in special operations or SAR, operating in Class G airspace in excess of 15NM offshore.[15]
- 4400 to 4477: Reserved for use by SR-71, YF-12, U-2 and B-57, pressure suit flights, and aircraft operations above FL600 (USA only).[17]
- 5000: Aircraft in Military Operations[15]
- 6000: Australia: Military flights in Class G airspace.[15]
- 7000:
- VFR standard squawk code when no other code has been assigned (ICAO)[13].
- UK: this code does not imply VFR; 7000 is used as a general conspicuity squawk.[12]
- 7001:
- Sudden military climb out from low-level operations (UK)[12]
- Used in some countries to identify VFR traffic (France, ...)
- 7004: Aerobatic and display code in some countries.[12]
- 7010: VFR circuit traffic code in the UK
- 707X: Paradrop activities in France (7070, 7071, 7072...)
- 7615: Australia: civil flights engaged in littoral surveillance.[15]
- 7777:
- Military interception (U.S.) ("Under no circumstances should a
pilot of a civil aircraft operate the transponder on Code 7777. This
code is reserved for military interceptor operations.")[18]
- Non-discrete code used by fixed test transponders (RABMs) to check
correctness of radar stations (BITE). (U.S., Germany, Netherlands,
Belgium, ...)
