Policy and Procedures use of TCAS / ACAS
ACAS II
Provides collision Avoidance Advice in the Vertical plane. 2 forms;
TA - Traffic Advisories
RA - Resolution Advisories
87
Traffic Advisory Actions: (TA)
Alerts Crew that an RA might follow
Visual search on that part of the sky TA indicates Traffic
ATC assistance can be requested regarding change of Flight Path
Do NOT manoeuvre on TA only
88
Resolution Advisory Actions (RA)
Respond immediately following RA indications, unless risking safety of the Aeroplane
1. Stall warning, Windshear and GPWS alerts have Precedence over ACAS
2.Visual traffic, may not be the same causing the RA.
Follow RA, even if conflict with ATC instructions
Don’t manoeuvre opposite of an RA
Radio ATC of any RA, example “Radar, TCAS RA”
When recovered, Clear of Conflict.
When clear return to previous clearance and notify ATC
89
In – Flight Fuel Checks
Flights less than 1 hour, once per Flight.
Longer Flights, Once per hour and note on the OFP. Every 30 minutes a visual check without taking note.
Differences acceptable due to:
APU Consumption
FQI Errors on Block Fuel on FOB (Water freezing in tanks also affect FQI)
FU indication tolerance
90
In -Flight Fuel Management
Arrive Destination Aerodrome with minimum of required Alternate Fuel + Final Reserve Fuel
Final Reserve Fuel, if no Alternate required.
If the Fuel is expected on arrival at Destination to be less than:
1. Alternate Fuel + Final Reserve Fuel, taking into account fuel to Alternate airport, and landing with minimum Final Reserve Fuel
```
2. Final Reserve if no Alternate required.
To save fuel if required:
Decrease Aircraft Seed. (Green Dot)
Direct routing.
Close to optimum Flight Level
Closer Alternate Airport
Land & Refuel
```
91
Landing Assured:
A landing is “assured” if, in the judgement of the Commander, it could be completed in the event of any forecast deterioration in the weather and plausible single failures of ground and/or airborne facilities, e.g. CAT II/III to CAT I.
92
Low Fuel State (minimum FUEL & MAYDAY FUEL_
MINIMUM FUEL – to ATC when having committed to Land at a specific Aerodrome, any change to existing clearance may result in Landing with less than planned Final Reserve Fuel.
Not an emergency situation, but can occur, as may result in Landing with less than FRF.
MAYDAY MAYDAY MAYDAY FUEL, when calculated usable Fuel upon Landing will be Less than the Planned Final Reserve Fuel
93

Classification of Turbulence
Classification of intensity may be defined as follows:
Intensity
Aircraft Reaction
Reaction Inside Aircraft
Light
Turbulence that momentarily causes slight, erratic changes in altitude and/or attitude.
Occupants may feel a slight strain against seat belts or shoulder straps. Unsecured objects may be displaced slightly. Food service may be conducted and little or no difficulty is encountered in walking.
Moderate
Similar to light turbulence but of greater intensity. Changes in altitude and/or attitude occur but the aircraft remains in positive control at all times. It usually causes variations in indicated airspeed.
Occupants feel definite strains against seat belts or shoulder straps. Unsecured objects are dislodged. Food service and walking are difficult.
Severe
Turbulence that causes large, abrupt changes in altitude and/or attitude. It usually causes large variation in indicated airspeed. Aircraft may be momentarily out of control.
Occupants are forced violently against seat belts or shoulder straps. Unsecured objects are tossed about. Food service and walking is impossible.
Extreme
Turbulence in which the aircraft is violently tossed about and is practically impossible to control. It may cause structural damage.

Volcanic Ash Operations / Limitations
Operations from Ash Contaminated airfields not permitted.
Over - Flight – May be planned up to 100 Nm
Under-Flight – (may be planned case by case, destination & alternate should be free of ash and within 320 Nm
Not permitted in Actual Contamination by visible Ash
Not permitted in easyJet No Fly Zone (MACC)
```
Forecast Low – MACC CYAN
Operations Unrestricted (over-flight & under-flight)
```
Forecast Medium – MACC GREY
Day / VMC without restrictions
IMC / Night – only if Satellite information is available to verify position of visible / discernible Ash – and Ash is avoided
Engine Monitoring purpose, All Ops required Crew send ACARS message on completion of Sector
Message format is: VOLCN no ash seen / encountered
Over-Flight – No restrictions
Under-Flight – No restrictions, should remain 5000 ft below know ash Layer
Forecast High – MACC RED or Contaminated Airspace.
Not Operate Flights known High Contamination / High Ash Concentration.
If Satellite confirms Ash below LOW Contamination, then no restrictions.
OM - A 8.3.8.6.2
100
Initial Crew Response to Volcanic Ash Encounter
If Visible Ash is encountered:
Make 180 degree Turn
Notify Air Traffic Control
Apply Volcanic Ash - QRH Procedure
When out of Volcanic Ash
Check Engine & Systems
If Abnormal indications, consider Divert and/or declaring Emergency
Report Volcanic Ash by:
Push Event Button
Approx. Position (Bearing/Distance/Vertical height) of ash in relation to Aircraft.
Special Air Report must be made to ATC in accordance with the MODEL VAR instructions.
101
Temperature Inversion effect
Normal SAT decrease 2 C for each 1000 ft
Large Temperature Inversions can degrade Take Off Performance after Take Off and also Go Around Climb Performance.
Cruising level may also be reduced with Temperature inversion.
Lower Level – poor visibility / fog for prolonged periods.
Airspeed and Pitch may vary rapidly – intervene as required.

Circling with Prescribed Tracks
Familiar with Terrain and Visual cues, to be used in Weather conditions at or above minima. (Audio / Visual briefing)
Beginning a Level Flight phase, the Instrument Approach Track should be maintained until reaching the Divergence point, if no required Visual Reference a missed Approach shall be flown.
Once established on the Prescribed Tracks, Visual Reference does not need to be maintained, but Obstacles and Ground shall remain in sight while on the Prescribed Tracks.
The missed Procedure for Normal Instrument Approach applies, Prescribed Tracks allows a Go-Around to achieve a Safe altitude, joining Downwind Leg of the Prescribed Track Procedure or the Instrument Missed Approach trajectory.

Fail Operational
A Flight Control System is Fail Operational,
In the event of a failure Below ALERT HEIGHT,
the Approach, Flare and Landing can be completed Automatically.
In event of a failure, the Automatic Landing System will operate in Fail Passive mode.
(eg. Loss of one Autopilot, redundancy in the Second Autopilot to land the Aircraft automatically)
135
Fail Passive
In the event of a failure, there is no Significant out-of-trim condition or deviation of Flight Path or attitude, but the Landing is not completed Automatically.
A Fail-Passive failure, the Pilot assumes control of the Aircraft.
(eg. 1 Autopilot lost, can still land Automatic, this is Fail Passive condition, however if this Autopilot fails, the pilot needs to take over control.)
136
Alert Height:
Radio Height based on Aircraft and its Fail Operational Landing System.
Operational use, failure Above the Alert Height of one of the Redundant systems in the aircraft, the approach would be discontinued and a Go-around, unless reversion to a higher decision height is possible.
If Failure Below Alert Height, it would be ignored, and the approach continued.

Punctuality Policy
Crew Report: STD - 35 Latest at the Aircraft
Green Light Boarding: First Wave Departures customers, should be released at a time to enable them to board at : STD - 25
Dispatcher / Gate Agent don’t need signal from Cabin Crew to confirm ready.
(exception Technical Problem, Minimum Cabin Crew required not onboard, Commander or SCM advices Dispatcher, boarding held until confirmed.
Early Departures:
Max 10 minutes ahead of schedule in any circumstances, so long as the Dispatcher has confirmed that boarding and loading have been completed.
Non – revenue flights, OCC must be consulted for revised slots etc.
Early departure from Stand to Remote Holding
Early Arrivals
Early Departure, may result in Slot infringement at destination. Could give a financial penalty.
Should manage arrival to be no earlier than STA – 15
Consider reducing Cost Index for punctuality
139
Offloading Passengers Late to Boarding Gate
If Pax Reports to Gate after closed, but before their baggage being offloaded, the Dispatcher is accountable for deciding if Pax should be accepted.
Decision based on best outcome of Punctuality.
If Baggage located, Dispatcher most likely refuse travel to Pax.
If Not located, Dispatcher will assess what will give the earlier Door Closed time. Dispatcher consults and agrees with the Commander.
