Operating Procedures — Pilot-in-Command

Annex 12 · Operating Procedures
6.1 — PIC at the Scene of an Accident
When PIC observes another aircraft or surface craft in distress — shall if possible and unless unreasonable/unnecessary:
⚠️ Command Responsibility — Non-SAR Aircraft First on Scene

If the first aircraft to reach the scene of an accident is NOT a search and rescue aircraft, it shall take charge of on-scene activities of all other aircraft subsequently arriving until the first SAR aircraft reaches the scene of the accident.

📊 On-Scene Command — Who's In Charge?
First aircraft to reach scene = SAR? YES SAR aircraft takes command NO First non-SAR takes command Commands ALL subsequent aircraft UNTIL 1st SAR a/c arrives SAR a/c arrives → takes over
6.2 — PIC Intercepting a Distress Transmission
📻 Whenever a distress transmission is intercepted — PIC shall if feasible:
💡 Exam Tip — Distress Transmission Steps

Remember the mnemonic: A-R-B-I-P — Acknowledge · Record position · Bearing · Inform RCC · Proceed (at discretion).

The key qualifier is "if feasible" — the pilot must do all five actions if feasible, but is not obligated if they genuinely cannot.

SAR Signals — Aircraft to Surface Craft

Annex 12 · Search and Rescue Signals
7.1 — Aircraft Directing Surface Craft to a Distress Location
📋 Signal Sequence — Meaning: "Follow Me to distress location"

The following manoeuvres performed in sequence by an aircraft mean that it wishes to direct a surface craft towards an aircraft or a surface craft in distress:

🔔 Important Note on Sound Signals

Due to high noise levels on board surface craft, the sound signals in (2) and (3) may be less effective than the visual signal in (1) and are regarded as alternative means of attracting attention.

Repetition of such manoeuvres has the same meaning.

7.2 — Aircraft Signal: "Assistance No Longer Required"
Signal meaning assistance is NO LONGER REQUIRED:

Crossing the wake of the surface craft close astern at a low altitude, and one of:

7.3 — Surface Craft Replies to Aircraft Signals
For Acknowledging Receipt of Signals (Meaning Understood)
1 Hoisting the "code pennant" (vertical red and white stripes) close up — meaning: understood
2 Flashing a succession of "T's" by signal lamp in Morse code
3 Changing heading to follow the aircraft
For Indicating Inability to Comply
1 Hoisting the international flag "N" (a blue and white checkered square)
2 Flashing a succession of "N's" in Morse code

Air-to-Ground Signals

Annex 12 · SAR Signals
✈️ Aircraft Acknowledging Ground Signals

The following signals by aircraft mean that the ground signals have been understood:

☀️ During DAYLIGHT Hours

Rocking the aircraft's wings

A clear, visible acknowledgement that ground signals are understood.

🌙 During DARKNESS Hours

Flashing on and off TWICE the aircraft's landing lights, or if not so equipped, by switching on and off TWICE its navigation lights.

⚠️ Lack of Signal = Not Understood

Lack of the above signals indicates that the ground signal is NOT understood.

MCQ Practice Questions & Answers

DGCA Examination Style Questions
📝 Instructions

The following 17 questions are sourced directly from the textbook. Correct answers are highlighted in green. Explanations drawn from the regulatory text are provided below each question.

Q1 The units responsible for promoting efficient organization of search and rescue service are:
✅ ANSWER: B
The RCC and RSC are specifically responsible for promoting efficient organization of SAR services and coordinating operations. ACCs and FICs serve ATS functions, not SAR management.
Q2 Three aircraft (1), (2) and (3) arrive successively at ten minute intervals overhead the scene of a recent aircraft accident. Aircraft (1) is unable to establish contact with the SAR Centre. Aircraft (2) is able to contact the SAR Centre. Aircraft (3) is a SAR helicopter. The command of the situation is the responsibility of:
✅ ANSWER: A
The first aircraft on scene (1) takes command. When (2) arrives, command may pass by mutual consent. When the SAR helicopter (3) arrives, it should eventually take command as the designated SAR asset — command passes by mutual consent to (3).
Q3 What is the meaning of the symbol "V" in the ground-air visual signal code for use by survivors?
✅ ANSWER: B
V = Require Assistance (general help). X = Require Medical Assistance. "Landing here impossible" is not part of the survivor's ground-air code.
Q4 What is the meaning of the symbol "LLL" in the ground-air visual signal code for use by rescue units?
✅ ANSWER: A
LLL = Operation Completed. LL = We have found ALL personnel. XX = Cannot continue / returning to base.
Q5 Which of the following is NOT an international distress frequency?
✅ ANSWER: C
Recognised international distress frequencies include 121.5 MHz (civil), 243.0 MHz (military), 2182 kHz (maritime), and 406 MHz (COSPAS-SARSAT). 2430 kHz is NOT an internationally designated distress frequency.
Q6 An aircraft is flying over a mountainous region in which a search is being carried out to find the survivors of an aircraft accident. The pilot sees a ground signal in the form of an "X". This indicates:
✅ ANSWER: C
X = Require Medical Assistance — this is one of the five survivor ground-air visual signal codes. V = Require Assistance (general).
Q7 At night an aircraft observes a luminous signal requesting help. To indicate that he has received these ground signals, the pilot must:
✅ ANSWER: C
The air-to-ground signal at night confirming ground signals understood = flashing landing lights (or nav lights) ON and OFF TWICE.
Q8 The color identification of the contents of droppable containers and packages containing survival equipment should take the form of coloured streamers according to the following code:
✅ ANSWER: C
The text specifies that survival equipment dropped by SAR containing food and water will be in containers indicated by Blue streamers. Blankets/protective clothing are also identified by blue in the full international colour code.
Q9 COSPAS-SARSAT is:
✅ ANSWER: C
COSPAS-SARSAT is a SAR satellite-aided tracking system operating on 406 MHz. India participates through INMCC Bangalore, LUTs at Bangalore and Lucknow.
Q10 You are flying in Mumbai FIR when you intercept a distress call. You record the message and tell Mumbai FIC. The radio operator at Mumbai tells you to standby. What should you consider doing whilst awaiting instructions?
✅ ANSWER: C
Per the procedure for intercepting a distress transmission (step e): "At the pilot's discretion, while awaiting instructions, proceed to the position given in the transmission."
Q11 Search and Rescue services within the territory of ICAO contracting states are provided:
✅ ANSWER: A
Contracting states are obligated to provide SAR services on a 24-hour basis — no exceptions, no authority discretion required.
Q12 Contracting States shall establish a rescue co-ordination centre:
✅ ANSWER: B
One RCC per Search and Rescue Region. In India, four RCCs correspond to four FIRs: Delhi, Mumbai, Kolkata, Chennai.
Q13 A Rescue Unit is:
✅ ANSWER: B
A Rescue Unit is defined as a unit composed of trained personnel, provided with equipment suitable for the expeditious conduct of SAR operations.
Q14 Which of the following statements regarding Alerting service is correct?
✅ ANSWER: C
Alerting Service and FIS are frequently collocated and provided by the same ATS unit (typically a FIC). The Alert phase (ALERFA) is established after 30 minutes of no communication — but the Alert phase is triggered when an aircraft is overdue, not simply when no communication was received in 30 minutes from when it should have been received (that is closer to the Uncertainty phase).
Q15 Whenever a distress signal and/or message or equivalent transmission is intercepted by the PIC of an aircraft, he shall:
✅ ANSWER: A
Both recording the position AND taking a bearing are required actions (if feasible). Answer A correctly combines both obligations. Neither B nor C alone is the complete requirement.
Q16 What is the meaning of SAR signal "N" when used by survivors on the ground:
✅ ANSWER: A
In the survivor ground-air visual code: N = No / Negative. X = Require Medical Assistance. V = Require Assistance.
Q17 Survival equipment, dropped by SAR and containing food and water will be packed in containers and indicated by streamers of following colour:
✅ ANSWER: B
Directly from the text: "Survival equipment, dropped by SAR and containing food and water will be packed in containers and indicated by streamers of Blue colour."
