Which chapter of the AIP contains a list of “location indicators”?
- AAGA
- BGEN
- CENR
Why that is the answer
The list of ICAO location indicators — the four-letter codes assigned to aerodromes and other aeronautical facilities within a State — is general reference information applicable across the whole AIP rather than something specific to one route or one aerodrome, so Annex 15 places it in GEN, in the section holding tables and codes such as abbreviations, chart symbols, and location indicators. A pilot or dispatcher who needs to decode a location indicator seen anywhere else in the AIP — on a chart, in a NOTAM, in a route description — needs one single reference table, and keeping it in GEN avoids scattering it across ENR or AD entries. "AGA" is a heading from the pre-restructuring AIP layout and does not correspond to a current top-level part; ENR is route-specific information and is not the natural home for a State-wide code reference table.
- Location indicators are a State-wide reference table, not information tied to one aerodrome or one route.
- General reference tables (abbreviations, codes, chart symbols, location indicators) live in GEN.
- Keeping this list in GEN avoids repeating or scattering it across ENR or AD entries.
- "AGA" is a legacy heading not used in the current three-part structure.
- ENR is route-specific and not where a general code table belongs.
- Mnemonic — One code table for the whole book: location indicators sit in GEN.

What must make up the identification of each prohibited, restricted and danger area?
- AThe nationality letters assigned to the state or territory for location indicators, followed by the letters P, R or D and figures
- BThe letters P (Prohibited), R (Restricted) and D (Dangerous) for the area concerned, followed by figures
- CThe letters P (Prohibited), R (Restricted) and D (Dangerous), followed by figures
Why that is the answer
ICAO Annex 15's standard for identifying prohibited, restricted and danger areas, used in the ENR 5.1 listing, requires the identification to be built from three components in order: first the nationality letter(s) assigned to the State — the same letters used for that State's location indicators — then one of the letters P (Prohibited), R (Restricted) or D (Dangerous) denoting the type of area, and finally a number distinguishing that particular area from others of the same type in the same State. The nationality-letter prefix exists because prohibited, restricted and danger area designators must be unique on a global, not just national, basis — many States independently create a 'P1' or 'R3,' and without a national prefix these would collide and be ambiguous to a pilot crossing borders or consulting charts covering more than one country. A designator built only from the type letter (P, R or D) plus a number — whether or not it adds a descriptive phrase such as 'for the area concerned' — omits this nationality prefix entirely, and is therefore not sufficient for the area to be uniquely and internationally identifiable, which is exactly why Annex 15 mandates the nationality-letter component as part of the identification, not as an optional decoration.
- ICAO Annex 15 (ENR 5.1) requires prohibited/restricted/danger area identification to have three parts: State nationality letters, then P/R/D, then a number.
- The nationality letters are the same ones used for that State's location indicators, ensuring global rather than merely national uniqueness.
- Identifiers built only from the P/R/D letter plus a number, with or without an added descriptive phrase, omit the nationality prefix and so are not unique across States.
- Uniqueness matters because different States independently assign area numbers, and duplicate designators would confuse cross-border chart users.
- The correctly complete identification is: nationality letters, then the type letter (P, R or D), then a distinguishing number.
- Mnemonic — Name the country before you name the danger: nationality letters come first.

Frequently asked
How many Aeronautical Information Services questions are there for the DGCA CPL Air Regulations paper?
Avielevate's bank carries 31 published Aeronautical Information Services questions for Air Regulations, mapped across 1 learning objective. Every one has its answer key, and explanations are being written across the whole bank.
How much of the Air Regulations paper is Aeronautical Information Services?
The DGCA does not publish a per-chapter breakdown of its papers, so nobody can honestly tell you — and we will not guess. What we can tell you is what students who have just sat a paper reported meeting, which is measured rather than rumoured: that is the exam recall report inside the app.
What is the best way to revise Aeronautical Information Services?
Sit a short timed set on this chapter alone, tag how sure you were of each answer, then drill the two that actually leak marks: the ones you got right while guessing, and the ones you got wrong while confident. Avielevate does that tagging for you and puts anything you got wrong back in front of you on a spaced schedule.
