uncoupled) (Max wind/Mean gust/XWC/TWC

Max TWC: 10kts
Wind limits (coupled approach) (XWC/TWC)
XWC: 32kts
TWC: 14kts
When IAW AVOs are you allowed to land outside of wind limits?
ONLY with specific authorisation of OC 42SQN, are you allowed to land/take off at an aerodrome that exceeds wind limitations. (Part 3, Leaflet K9, AVOs)
Practical application of DDA
What approaches do we do it for?
Why do we do it?
To better achieve a stabilised final approach segment for non precision approaches (including RNAV), approaches should be flown at constant descent final approach (CDFA). If CDFA is used, descent below MDA could happen when executing the MAP. Therefore, the go around decision/initiation should be done before MDA (at DDA)
> in simple terms; DDA allows us to make a decision before MDA & execute the MAP if required without continuing below MDA.
How to calculate DDA and what does it stand for?
Derived Decision Altitude
MDA +50ft = DDA
When to not use DDA (3) & alternative approaches to this.
- If the Captain is unable to attain required visual reference on the first appch using CDFA and a DDA, OR
- If the appropriate vertical guidance is not avlble,
OR - If it considered more appropriate by the a/c captain.
> A step down (dive & drive) or CDFA approach to MDA may be used.
Why are STARs used? (4)
- To reduce RTF
- Standardise arrival instructions
- Reduce possibility of error in aircraft routing
- Provide positive routing in event of a/c comms failure.
Approaches; when can you track direct outbound over the aid/ when do you need to conduct a reversal procedure?
- Can track direct overhead the aid outbound if you are within 30 deg L or R of the outbound track.
- If outside this tolerance, a reversal must occur via a Procedure turn/base turn or a racetrack
Reversal procedures; requirements (3)
- Strict adherence to directions & timings required
- Entry track to the procedures must be +/- 30deg
- Except for DME distance limited procedures, reversal speed limitations apply from procedure commencement
CAT B VaT
91 -120kts IAS
CAT B Initial appch speeds
120 - 180kts IAS
CAT B Max speed for reversal procedures
140kts IAS
CAT B Final appch speeds
85-130kts IAS
CAT B max speed for visual maneuvering (circling)
135kts IAS
CAT B max speed for MAP
Other parameters?
150kts IAS (unless otherwise specified on appch plate)
- 2.5% min clb gradient for 98ft obstacle clearance
- Min bank angle 15deg AoB
Describe a 45/180 deg Procedure turn
(3 steps)
(Also the NOTE)
Consists of;
- specified outbound track & timing from the aid (NO MORE THAN 3 MINS), then;
- a 45deg turn away from the outbound for 1 MIN FROM THE START OF THE TURN (CAT A & B), then;
- a 180deg turn in the opposite direction to intercept the inbound TRK.
NOTE; an 80deg procedure turn may also be used when a 45deg procedure turn is depicted.
Describe an 80/260 deg Procedure turn
3 steps
Consists of;
- specified outbound track and timing from the aid (NO MORE THAN 3 MINS), then;
- an 80deg turn away from the outbound TRK, then, once wings lvl;
- an immediate 260deg turn in the opposite direction to intercept the inbound TRK
Describe a Base turn
2 steps
Consists of;
- Turn immediately overhead the aid onto a specified outbound TRK and timing from the aid or specified distance, then;
- a turn to intercept the inbound TRK
Race Track - compare to holds
E/S/OO/P/M/A
Same procedures as holds apply (but leg times/distances should be specified and considerations should be applied);
- entry TRK must be within +/- 30deg unless entry is protected
- Speed not abve Max applicable to CAT B
- When a longer outbound time is published, Offset entry is limited to 1min 30secs, then outbound leg is paralleled for the remaining distance/time
- During Parallel entry, the inbound final appch track must be intercepted prior to the facility
- Maneuvering, as far as possible, will be done on the holding side of the inbound track.
- Specified min altitudes apply until the a/c is established on the final inbound track
