⚠️ Regulatory Delays — Know These!
Delays may be expected for the second aircraft to push-back when it is parked adjacent to another aircraft being pushed-back.
Delay in take-off due to restrictions in the ATC clearance and over-flights or the appropriate ATS authority.
Delay when proceeding on the same track/level, or climbing through the level, or to climb at a higher rate of climb behind a preceding traffic to establish the prescribed separation.
A departing aircraft requesting the same cruising level as an over-flying aircraft may have to accept an alternate level or delay its departure to establish prescribed separation.
§4 · Take-Off and Landing
🚨 Absolute Rules — No Exceptions
The pilot-in-command shall not take-off or land without a clearance from the appropriate ATC unit.
The pilot-in-command shall not run-up on the runway in use unless authorised by Aerodrome Control.
🟢 Engine Run-Ups — Where They Can Be Done
Engine run-ups in the holding pan or runway holding position clear of the runway in use may be carried out — subject to approval by Aerodrome Control.
Minimum Runway Occupancy Procedures
To increase runway capacity it is essential to minimise the runway occupancy time. Follow these procedures:
1
Cockpit checks should be completed prior to lineup. Any checks requiring completion on the runway should be kept to the minimum required.
2
Pilots must be able to commence the take-off run immediately after take-off clearance is issued.
3
Pilots not able to comply must notify ATC prior to commencement of taxi.
4
Pilots of arriving aircraft are reminded that rapid exits from the landing runway enable ATC to apply minimum spacing on final approach — achieving maximum runway utilisation.

Separation of Departing Aircraft
⚠️ When May Next Departure Commence?
A departing aircraft will not normally be permitted to commence take-off until:
The preceding departing aircraft has crossed the end of the runway-in-use, OR
The preceding departing aircraft has started a turn, OR
All preceding landing aircraft are clear of the runway-in-use
Take-Off Clearance
🟢 When Can Take-Off Clearance Be Issued?
Take-off clearance may be issued to an aircraft when there is reasonable assurance that the separation will exist when the aircraft commences take-off.
💡 Immediate Take-Off Clearance
In the interest of expediting traffic, a clearance for immediate take-off may be issued to an aircraft before it enters the runway. On acceptance of such clearance — the aircraft shall taxi out to the runway and take off in one continuous movement.
💡 Take-Off Clearance — Runway Designator
To reduce the potential for misunderstanding — the take-off clearance shall include the designator of the departure runway.
📐 Departure / Arrival Separation — Position Limits (Doc 4444)

§24 · Wind Shear Advisories
📖 Definition of Wind Shear
Wind shear is a sustained change in the wind velocity along the aircraft flight path, which occurs significantly faster than the aircraft can accelerate or decelerate. It can occur at any level, but it is 'low level wind shear' occurring from the surface to a height of approximately 1,500 feet, which can cause problems of sufficient magnitude to affect the control of aircraft in departure or final approach phases of flight.
🟢 Wind Shear Reporting Procedure
Whenever a pilot reports wind shear conditions to ATC — the information shall be passed to subsequent arriving and departing aircraft until either:
Confirmation is received that the condition no longer exists, OR
Wind shear information has been included in ATIS and the flight crew reports receipt of the appropriate ATIS designator
Reports on wind shear from aircraft should be passed to the Meteorological office.
Designation of Hot Spot
💡 Hot Spot
The aerodrome operator shall whenever necessary designate a location or several locations on the movement area of the aerodrome as hot spot(s). The hot spot(s) shall be charted in accordance with Annex 4.
§25 · Coefficient of Friction
💡 Context
The table below was developed from friction data collected only in compacted snow and ice — and should not be taken as absolute values applicable in all conditions. Surface condition information (including estimated surface friction) must be provided for each third of a runway. The "first part" always means the first third of the runway as seen in the direction of landing.

⚠️ Key Exam Point — Runway Segments
The runway is divided into thirds (1/3 segments) for reporting surface condition. When giving landing information, sections are referred to as first, second, or third part of the runway. The first part always means the first third of the runway as seen in the direction of landing.
Section 8 · Exam Questions & Answers
§26 · DGCA Exam Questions — Chapter 8
📖 About This Section
These 12 questions are taken directly from the DGCA examination bank for this chapter. Correct answers are highlighted in green with detailed regulatory explanations.
Q1 When instructed by ATC to hold short of Runway, pilot should stop:
A) With nose gear on hold line
B) So that no part of the A/c extends beyond hold line
C) So that the Flt Deck Area of A/c is even with the hold line
📝 Explanation
When instructed to hold short, the entire aircraft must remain clear — no part should extend beyond the hold line. The nose gear being on the hold line or the flight deck being level with it would mean parts of the aircraft are beyond it.
Q2 The following aircraft will be given priority to land:
A) An aircraft with VVIP on board
B) An aircraft with critical shortage of fuel
C) A scheduled aircraft
📝 Explanation
An aircraft with a critical shortage of fuel is in a compelling emergency — this is Priority 1 in the priority rules. A VVIP aircraft is Priority 5. A scheduled aircraft has no special priority.
Q3 Apron is an area on aerodrome where following activities take place:
A) Loading/unloading of passengers, mail and cargo only
B) Parking of aircraft only
C) Loading/unloading of passengers, mail and cargo, fueling, parking or maintenance
📝 Explanation
The apron is a defined area where aircraft stand for purposes of loading/unloading passengers, mail, cargo, fuelling, parking, or maintenance — i.e. all ground handling activities.
Q4 For safety reasons, a person should remain away from a jet engine by at least:
A) 100'
B) 200'
C) 300'
📝 Explanation
The jet blast hazard zone — persons should remain at least 200 feet away from operating jet engines for safety. This relates to the wake turbulence and jet blast hazard provisions.
Q5 Movement area of an aerodrome constitutes the following:
A) Area including runways/taxiways excluding apron
B) Area excluding taxiways but including runways and apron
C) Area including runways / taxiways / aprons
📝 Explanation
The Movement Area = Manoeuvring area (runways + taxiways) + Apron. It is the total area used for aircraft surface movements.
Q6 The manoeuvring area of an airport is that area:
A) Normally referred to as the ramp or apron
B) Used for taxiing, taking off and landing
C) Used when taxiing to and from the parking area
📝 Explanation
The Manoeuvring Area = Runways + Taxiways (excluding apron). It is the portion of an aerodrome used for take-off, landing and taxiing — but NOT the apron/ramp.
Q7 An Aircraft shall report "long final" when it is at _____ from the approach end of the rwy:
A) 8 NMs
B) 4 NMs
C) 1 NMs
📝 Explanation
As per the visual circuit diagram in this chapter — Long Final is defined as the position beyond 4 NM, up to 8 NM from the approach end of the runway. An aircraft at 8 NMs would report "long final".
Q8 What defines a controlled aerodrome?
A) It must be located within a CTR
B) It must have a control tower giving an ATC service
C) It must have a control tower and be in a CTR
📝 Explanation
A controlled aerodrome is one where an ATC service is provided to aerodrome traffic — which requires a control tower providing ATC service. It does not necessarily have to be located within a CTR.
Q9 Aerodrome traffic is considered to be:
A) Aircraft on the movement area and flying in the vicinity
B) Aircraft on the manoeuvring area and flying in the vicinity
C) Aircraft on the movement area only
📝 Explanation
Aerodrome traffic includes all aircraft on the movement area (runways + taxiways + apron) AND aircraft flying in the vicinity of the aerodrome (including traffic circuits).
Q10 Aircraft shall not be held closer to a runway-in-use:
A) Than at a runway-holding position
B) Than at runway edge
C) Than at 40 m from the runway edge
📝 Explanation
Aircraft shall not be held closer to a runway-in-use than at a runway-holding position. The distances (50m or 30m) are from the runway edge to the holding position, not the holding limit itself.
Q11 Friction Co-efficient due to snow — in how many segments is runway divided based on friction level?
A) 1/2
B) 1/3
C) 1/4
📝 Explanation
The runway is divided into thirds (1/3 segments) for surface condition reporting. Information is provided for each third — referred to as first, second, or third part of the runway.
Q12 Runway friction coefficient 0.20 means estimated surface friction:
A) Good
B) Medium to Good
C) Poor
📝 Explanation
A coefficient of 0.25 and below = POOR (Code 1). Since 0.20 is below 0.25, it is in the POOR category. This is the most dangerous friction level — extreme braking degradation on contaminated runways.
