Brunei DCA CPL(A) Operational Procedures flashcards

32 cards. Read the term and the definition here. The deck at the top of this page is optional.

Final reserve fuel

Fuel for 30 minutes of holding at 1500 ft above the alternate aerodrome in ISA conditions, required for turbine aeroplanes at the destination.

Contingency fuel

Fuel allowance of 5% of trip fuel or 5 minutes of holding at 1500 ft, whichever is greater, unless approved procedures permit a different allowance.

Alternate fuel

Fuel for a missed approach at destination, climb, cruise, descent, approach and landing at the alternate, including any published approach procedure.

Trip fuel

Fuel required from brake release at departure to touchdown at destination, including taxi-out and taxi-in allowances where the operator specifies.

Manoeuvring area

Part of the aerodrome used for take-off, landing and taxiing of aircraft, excluding aprons and the apron taxiway areas.

Runway holding position

Marking of two solid and two dashed yellow lines; the solid lines are on the runway side and must not be crossed without clearance.

Conditional line-up clearance

Clearance to enter the runway that names the preceding traffic and the condition; it must be read back in full before action.

Aerodrome operating minima

Minimum visibility or RVR and decision altitude required for an approach, based on approach category, lighting and the approved procedure.

Transition altitude

Altitude at which the altimeter is set to standard pressure 1013.2 hPa; above it the aircraft operates on flight levels.

Transition level

Lowest usable flight level above the transition altitude; it varies with the QNH and is provided by ATC.

Approach category

Category based on Vat (1.3 times Vso): Cat A below 91 kt, Cat B 91-120 kt, Cat C 121-140 kt, Cat D 141-165 kt.

Standard departure gradient

Default climb gradient of 3.3% (200 ft per NM) for instrument departures; steeper published gradients require a performance check.

MAYDAY call

Distress signal spoken three times on 121.5 MHz or the assigned frequency, followed by identification, position, nature of distress and intentions.

PAN-PAN call

Urgency signal spoken three times, used when a situation is urgent but no immediate danger of loss of life exists.

Lost communication squawk

Transponder code 7600, selected when two-way radio communication is lost, followed by the published lost-communication procedure.

Mandatory readback items

Clearances, runway-in-use, altimeter settings, SSR codes, level instructions, headings and frequencies must be read back to ATC.

ATC clearance

Authorisation to proceed under specified conditions; it does not relieve the commander of responsibility for terrain and obstacle clearance.

Conditional clearance readback

The readback repeats the condition and the instruction, including the preceding traffic, so ATC can verify correct understanding.

Speed control by ATC

Assigned speeds are given in multiples of 10 kt; the pilot must advise if unable to comply and resume published speeds when cancelled.

Clarification of clearance

If a clearance is not understood or cannot be complied with, the pilot must request clarification or an amended clearance before proceeding.

Emergency descent

Procedure using oxygen masks, transponder 7700 and maximum practicable rate of descent, with a MAYDAY broadcast of position and intentions.

Engine failure after take-off

Establish glide, select a landing area within 30 degrees of the flight path, and avoid turning back below 500 ft unless published.

Ditching procedure

Approach into wind or along the swell at minimum speed, gear up, flaps at the recommended setting, with exits and life rafts briefed.

Time of useful consciousness

At FL350 it is about 30-60 seconds; at FL250 about 3-5 minutes; at FL400 about 15-20 seconds without supplemental oxygen.

Severe icing conditions

Icing associated with large supercooled droplets, often freezing rain, that can exceed the capability of the airframe ice protection system.

Holdover time

Period after anti-icing fluid application during which take-off is permitted; it depends on fluid type, precipitation and temperature.

Clear ice

Ice formed by large supercooled droplets freezing slowly on impact, producing a heavy, transparent and hard accumulation.

Wind shear go-around

Initiate a go-around if airspeed changes by more than 15 kt or vertical speed by more than 500 ft/min during approach.

Balanced field length

Field length at which accelerate-stop distance equals take-off distance to 35 ft, with V1 selected to minimise the required length.

Second segment climb gradient

Minimum gradient with one engine inoperative and gear up: 2.4% for two-engine, 2.7% for three-engine and 3.0% for four-engine aeroplanes.

Zero fuel mass

Dry operating mass plus traffic load; it must not exceed the maximum zero fuel mass and affects the centre of gravity position.

Centre of gravity limits

Forward limit is set by elevator authority and landing flare; aft limit by static stability and stall recovery characteristics.
