DGCA Air Regulations: Approach Control Service Questions

12 exam-style Approach Control Service questions for the DGCA Air Regulationspaper (CPL & ATPL). The first 12 are free below with answers and explanations — sign up free to practise all of them with progress tracking.

  1. Q1

    On a non-precision approach, unless the required visual reference has been established, descent is not permitted below the:

    • AMDA
    • BDA
    • CN/A
    • DN/A
    Show answer

    Correct answer: A. MDA

    On a non-precision approach like a VOR or NDB approach), there is a floor called the MDA — Minimum Descent Altitude. You must level off at the MDA and fly along it until you can see the runway. If you cannot see it by the missed approach point, you go around. You must NEVER go below the MDA without seeing the runway. DA is used for precision approaches like ILS — a different type of approach.

  2. Q2

    If the crew of an arriving aircraft approaching a controlled aerodrome reports field in sight, a clearance for a visual approach may be g ranted only under certain conditions. Which is correct?

    • AThe reported meteorological visibility must be at least 8 km.
    • BThe clearance is valid only for VFR traffic.
    • CATC will ensure separation from other controlled traffic.
    • DThe aircraft should already be passing the Final Approach Fix FAF).
    Show answer

    Correct answer: C. ATC will ensure separation from other controlled traffic.

    When a pilot reports field in sight and is cleared for a visual approach, ATC does not just wave goodbye and stop watching. ATC continues to provide separation from all other controlled traffic in the area. The pilot handles their own navigation visually, but ATC keeps managing the airspace around them to make sure no other aircraft gets too close. Safety is always a team effort between pilot and ATC.

  3. Q3

    If an arriving aircraft is on a straight-in approach, when can a departing aircraft take off in any direction?

    • AUntil five minutes before the arriving aircraft is estimated to be over the instrument runway
    • BUntil ten minutes before the arriving aircraft is estimated to be over the instrument runway
    • CUntil two minutes before the arriving aircraft is estimated to be over the instrument runway
    Show answer

    Correct answer: A. Until five minutes before the arriving aircraft is estimated to be over the instrument runway

    .

  4. Q4

    For controlled traffic near an airport, under what circumstances can separation minima be reduced?

    • AAt the discretion of the air traffic controller
    • BWhen the commander in the following aircraft has the preceding aircraft in sight and is able to maintain own separation
    • CIf the commander of the involved aircraft so requests
    Show answer

    Correct answer: B. When the commander in the following aircraft has the preceding aircraft in sight and is able to maintain own separation

    .

  5. Q5

    At the start of the final approach, if the controller has wind component information, they must inform aircraft of any significant changes in mean surface wind direction and speed; what is the significant change for the mean tailwind component?

    • A3kt
    • B4kt
    • C2kt
    Show answer

    Correct answer: C. 2kt

    .

  6. Q6

    The EAT must be communicated to the pilot promptly if the anticipated delay is:

    • A5 minutes or more
    • B15 minutes or more
    • C20 minutes
    Show answer

    Correct answer: A. 5 minutes or more

    .

  7. Q7

    A "Visual Approach" can be conducted under which of the following conditions?

    • ADuring VFR flight, there should be a visibility of 5 km or more
    • BDuring IFR flight, if the cloudbase is 1000ft more than the appropriate DA or MDA for that procedure
    • CDuring IFR flight. if there is permanent sight on the movement area and the underlying ground
    Show answer

    Correct answer: C. During IFR flight. if there is permanent sight on the movement area and the underlying ground

    .

  8. Q8

    What is the purpose of the "Time Approach Procedure" in managing the arrival of multiple aircraft?

    • ATo maintain a specified speed during the approach procedure
    • BTo pass the specified point inbound at the previously notified tiem
    • CTo apply a step down descent between aircraft in the approach sequence
    Show answer

    Correct answer: B. To pass the specified point inbound at the previously notified tiem

    .

  9. Q9

    In VMC conditions during an IFR arrival procedure, who is responsible for traffic avoidance?

    • AThe radar controller
    • BThe pilot in command
    • CThe approach controller
    Show answer

    Correct answer: B. The pilot in command

    .

  10. Q10

    If the crew of an arriving aircraft reports "field in sight" when approaching a controlled aerodrome, a clearance for a "visual approach" may be granted under specific conditions.

    • AThe meteorological visibility must not be less than 8km
    • BThe approach must be passing the FAF
    • CThe air traffic controller will provide separation to other controlled traffic
    Show answer

    Correct answer: C. The air traffic controller will provide separation to other controlled traffic

    .

  11. Q11

    Which statement is accurate regarding a "visual approach" in controlled airspace (Class C)?

    • AATC will apply separation with other traffic
    • BThe pilot has to apply separation with other traffic
    • CATC will apply separation with other arriving traffic
    Show answer

    Correct answer: A. ATC will apply separation with other traffic

    .

  12. Q12

    What is the minimum degree of divergence required between departing aircraft for a one-minute separation after take-off?

    • A30° immediately after take-off
    • B15° immediately after take-off
    • C45° immediately after take-off
    Show answer

    Correct answer: C. 45° immediately after take-off
