Enr 1.5 Flashcards
Climb in evaluated sector.
AC must maintain T/O climb gradient as required by departure procedure for track being flown and climb on departure to mnm 400’ or other specified.
If AC is climbing through 2 or more sectors higher climb gradient applies.
Rate of climb required
Gradient percent x Groundspeed x 1.013
Whats a SID? Where does it start and what’s the climb gradient
Standard instrument departure used to standardise departure instructions reduce RTF congestion, chance of aircraft error routing and provide positive routing for comm fail.
Starts at a point 16ft above departure end of runway .
3.3% or 200ft per NM, must. Climb on runway centreline to 400’ above departure end of runway before commencing a turn.
Take off minima
Either on AD2 or if not specified, 300ft ceiling 1500m visibility
Reduced Takeoff minima
Zero cloud ceiling, visibility at or above 800m provided
Runway has centreline marking or lights, and T/O wx is confirmed by pilot, AD2 allows for reduced takeoff minima to be used, any obstacles are taken into account and if aircraft is AC is multi engine prop, equipped with auto feather or coarse system.
Holding altitudes
1000’ above normal, 2000’ mountains
IAS for holding patterns
14,000’ 170kt Cat A and B
Outbound timing
Below 14,000 1 minute above 14,000 1 and a half
Turns
Made at rate one turn or 25º whichever requires less bank
Onwards clearance time and expected approach time
Onwards - event that an AC is held en route or at a location other then initial approach fix, ac will be given onwards clearance time. The time it can be expected to leave holding location
Expected approach time - even ac is instructed to hold at initial approach fix, if delay will exceed five minutes an expected approach time will be passed.
Whats Vat and how to calculate it and what’s cat a
Speed at threshold
1.3 x Vs0
Less then 91kts

Operation below DA,DH, or MDA (9 references) 4T 3R AV
Cannot descend below MDA, DA unless:
- AC is continuously in a position form which a descent to a landing can be made at a Normal ROD using normal manoeuvres,
- circling approach, maintain aircraft within the appropriate circling area
- flight visibility is not less then the prescribed for approach
- one of the references are in sight
- approach lighting system
- threshold marking
- threshold lights
- REIL
- VASI
- touchdown zone or markings
-touchdown zone lights - runway markings or runway
- runway lights
Missed approach turn bank angle
Minimum turn of 15º
Missed approach design
Designed to provide a minimum obstacle clearance of 98’ to an aircraft climbing along specified missed approach path at a gradient of 2.5% (150ft/NM)
Radii of circling
1.68nm (3111m)
Met minima and alternate requirement
1 alternate aerodrome must be selected unless met conditions for at least 1 hour before and 1 hour after ETA of AD of landing ceiling will be at least 1000’ above minimums and vis is 5km or 2km more then minimum whichever is greater
Met minima of alternate and power supply requirement
Precision approach - ceiling 600ft or 200ft above DA
3000m vis or 1000m more then minimum which is greater
Non precision - 800’ or 200’ above MDA, visibility of 4000m or 1500m more then minimum, whichever is greater.
Must also have secondary electric power supply for ground based nav aid necessary for approach
Reference datum for takeoff minima for IFR and landing
AGL takeoff
