25
Destination alternates - weather window - number needed
At least one must have suitable conditions for ETA +/- 1 hr (if one is required). If weather at destination is unsuitable (or unknown), need 2 dest alts.
26
MDH vs DH reference point
DH uses threshold. MDH uses aerodrome elevation, unless threshold is more than 2m below in which case switches to threshold.
27
Planning minima for destination aerodrome
Visibility CAT.OP.MPA.110 and: - Precision: Aerodrome operating minima - NPA: Ceiling >= MDH
28
Planning minima for destination alternate aerodrome
CAT II/III: CAT I RVR CAT I: NPA RVR & ceiling >= MDH NPA: 1,000m extra RVR, 200ft extra ceiling Circling: Circling
29
Standard take off visibility requirements
500m RVR/VIS in day with no facilities OR 400m if either: i) Day with runway edge lights OR centreline MARKINGS ii) Night with runway end lights and either runway edge lights or centreline LIGHTS
30
Pilot assessment of RVR
PIC can assess RVR themselves instead of just using reported values
31
Low visibility take off - general requirements
Pilot & co-pilot trained & qualified. Both operator and aerodrome need to be approved for low visibility operations (LVO). Aerodrome needs low visibility procedures (LVP) to be established (if not operator must ensure equivalent procedures in place).
32
LVP & LVTO definitions [LVO]
LVP: Procedures for LVTO and cat II & III landings LVTO: Takeoff with 75m <= RVR < 400m
33
Destination weather - IFR takeoff - IFR in flight
Can only take off if weather at destination and/or at required alternates is ok. Once in the air can continue towards destination even if destination weather deteriorates, as long as alternate is within limits.
34
Noise Abatement Departure Procedure 1 (NADP 1)
Initial climb: V(2) + 10 to 20kt 800ft: Reduce thrust 3000ft: Retract flaps and accelerate to en-route climb This minimises noise near the aerodrome
35
NADP 2
Initial climb: V(2) + 10 to 20kt 800ft: Retract flaps and accelerate with full thrust to V(ZF) [zero flap] Flaps up: Reduce thrust, climb @ V(ZF) + 10kt 3000ft: Accelerate to en-route climb This minimises noise away from the aerodrome
36
When are special air reports required? (6)
- Mod./Sev. turb - Mod./Sev. icing - Sev. mountain wave - TS (obsc, embd, wdsp or squall) - Heavy DS/SS - Volcanic ash cloud, eruption or pre-eruption
37
V(AT) definition
or V(REF) Threshold speed = V(S0) * 1.3 or V(S1G) * 1.23
38
Approach categories
Based on V(AT) A: <91kt B: 91-120kt C: 121-140kt [A320] D: 141-165kt E: 166-210kt
39
Met visibility and RVR
For LANDING ONLY, if there is no RVR can convert met visibility to a converted meteorological visibility (CMV) based on multiples: HI lighting: 1.5x day, 2.0x night Other lighting: 1.0x day, 1.5x night No lighting: 1.0x day, n/a night Can use this as RVR, subject to minimum 800m.
40
Visual approach minimum RVR
800m
41
Non-precision approach - Technique used - RVR
MUST use CDFA RVR>= 750m
42
Minimum MDHs based on approach equipment
43
Circling approach minima
Use minimum MDH and RVR based on the max of figures for the instrument approach, figures for category of aircraft and figures from a table: A: 400ft, 1500m B: 500ft, 1600m C: 600ft, 2400m D: 700ft, 3600m
44
APV RVR
600m
45
Precision approach minimums
46
Below what height should altitude callouts reference radio altimeter?
200ft above THRESHOLD elevation [This is for CAT II/III approaches]
47
Landing field length safety factors (jet)
Full stop landing from 50ft above aerodrome (down to min 35ft for steep approach) at threshold within: Turbo-jet - 60% LDA
48
Effect of a reduction in headwind on approach
The immediate effect is reduction in IAS, thus reduction in lift and falling below the glideslope. Over time groundspeed will increase due to the lower headwind, but this will take a while to impact approach slope. Most important factor is the immediate loss of lift.
49
Response to windshear/microburst
Aircraft alerts can be sensitive so might only be "vigilance", but full response if microburst wind shear suspected. Then initiate "wind shear go around": - Full thrust - Pitch up to stick shaker - Retract speed brakes
50
Wake Turbulence - Aircraft weight categories (flight plan letters)
J: A380 H: >136,000kg M: 7,000kg to 136,000kg L: <7,000kg [MTOW]
51
Wake Turbulence - Separation times for LIGHT aircraft
52
Wake Turbulence - Separation times for MEDIUM aircraft
53
Wake Turbulence - Separation times for HEAVY aircraft
ONLY Departure behind SUPER - 2 mins
54
Wake Turbulence - Departing from intermediate runway position
Add 1 minute
55
Holdover period
This is the time you have to take off before anti-icing becomes ineffective. Starts from the beginning of application of anti-icing (the start of the second stage if 2 stage de/anti ice process).
56
Snowtam braking action codes at related braking coefficients
1) Poor: <0.25 2) Medium to poor: 0.26-0.29 3) Medium: 0.30-0.35 4) Medium to good: 0.36-0.39 5) Good: >0.40
57
Landing on wet/flooded runway - approach speed - landing firmness - devices to use
INCREASE approach speed (heavy rain causes decrease in lift?!) Firm landing to break film of water Use lift dumpers and reverse thrusters to reduce braking demand
58
Smoke detection zones vs fire detection areas
Fire detection in: - Jet engine bays - APU bays - Main gear bays Smoke elsewhere (e.g. cargo, cabins)
59
3 types of hydroplaning
Dynamic: Tread can't displace water Viscous: Film of water reduces friction Reverted Rubber: Heated rubber creates layer of steam
60
Where does viscous hydroplaning tend to happen?
In the touchdown zones
61
MOCA definition
+ 1000ft for terrain up to 6,000ft + 2000ft for terrain over 6,000ft In general this is separation you need to achieve everywhere!
62
Reason for a fuel jettison system
To achieve CS25 climb gradient requirements after take off
63
Runways: Damp Wet Contaminated
Damp: Not dry, but not shiny Wet: Visible dampness, or water up to 3mm Contaminated: More than 25% covered by standing water over 3mm or other contaminant
