IF Approaches Flashcards
What kinds of approaches can the Tiger fly?
ILS
RNAV
VOR/TACAN
Should the VOR/ILS box fail, what kinds of approach’s can be flown?
RNAV only
If the GPS fails, what kind of approach can be flown?
- VOR, but only if time based
- ILS is possible however ILS distance information must be provided by ATC at the IAF/FAF IOT
Can the Tiger system couple up to and fly and ILS or inbound VOR radial?
No, ILS uses manual COL setting and HDG mode
For an ILS, what should be shown on the MFDs and why?
PFD
NAV page in SECT mode —> Allows clear TRK info
How is the approach angle managed during an ILS?
4 axis mode, V/S is manually controlled via beep trims
How does the ARH tiger get distance information?
Through GNSS data only, ARH does not have DME
Since tiger doesn’t have DME, what restrictions does this have on which ILS approach can be flown?
CHECK:
Distance information from GNSS must be aligned
How can an ILS be tuned and what requirements are there to check accuracy?
NAV Page —> RNAV —> BCN List OR manual entry of freq
- When manually entering the ILS, its ident code must be checked
How should the NAV page be setup during an ILS?
- NAV page in SEC mode
You are approach the IAF on the ILS when you have en engine failure, what are your actions?
A - Speed back to 75KIAS, BF complete
N - Maintain the ILS
C - PAN call
A - Checklist/SDIP/before LDG Cx
On approach, what should DH/DA be set for each approach type?
ILS:
- DH = 150ft, 300ft if planned circling
- DA = Decision height
VOR/RNP
- DH = 250ft, 300 if planned circling
- DA = Set to the minima
You are arching to intercept the ILS, when and how should you intercept finals?
Passing the lead radial, set HDG for a 30ºintercept
What upper modes are used during an ILS approach?
3 axis: HDG and IAS, RoD is controlled with COL
4 axis: HDG/IAS/AAQ for the minima, beep V/S to control RoD
How can the glide slope RoD be calculated on approach? And what RoD would we expect for 75KIAS and 100KIAS approaches?
Ground Speed x 5
@100kts = 500ft/min
@75kts = 375ft/min
You are expecting to gain visual at the minima and fly straight in, what additional considerations are there to terminate?
Expect to be approx 250ft AGL @ 100KIAS, IOT slow down safely, decel to 75KIAS and approach to the far end
Once visual what actions should be completed?
- First pilot to gain visual takes over flying
- Landing light as required (by night)
- Maintain upper modes if circling, if not select TAC
What kind of VOR approach requires GNSS?
If the VOR uses DME distance instead of time
What restriction apply to RNAVs built on JMPS?
- Must use DAFIF WPs
- Must be checked by 2x COMD instrument rated pilots
- Must use the straight in fix
How can a RNAV route be checked airborne?
NAV page - 500k scale does it look right/correct direction?
CDU - Flight log, should have 2-3 mins between each WP
When an approach has a VNAV and LNAV minima, which should you use?
LNAV only
Since the MAPt is a fly over WP, how should you manage the AFCS so that it doesn’t fly past?
Switch to HDG mode then back to NAV mode
Explain how your actions are different if there is a turn between the MAPt and “H” WP compared with a straight on missed approach?
If there’s a turn, the NAV system will fly direct, not follow the smooth turn, therefore switch to HDG mode IOT turn on, then engage NAV mode
On a GNSS approach, what is the last point where you can manoeuvre within your sector?
Cannot manoeuvre past the FAF
How does the approach profile differ for a GNSS approach compared to all others?
Descend to MDA once within the last step IOT get visual
Explain your actions IOT fly the missed approach AEO:
One of the missed approach criteria met —> “Going around”
- Disengage ALT, PWR to MCP (If turn after MAPt use HDG)
- NFP engage MA altitude
- R/T call, RQST reposition
Explain your actions IOT fly the missed approach OEI:
One of the missed approach criteria met —> “Going around”
- Disengage ALT, PWR to MCP, bleed RRPM to 315 (If turn after MAPt use HDG)
- NFP engage MA altitude
- R/T call, RQST reposition
Explain what admin must be completed passing the IAF and then through the FAF? 4 —> 2
Through IAF:
- Pre LDG Cx
- Satellites/Horizontal Accuracy
- QNH validity
- 100k scale (WPTs on)
Through FAF:
- R/T
- Confirm above 4 items checked
What are the main components of “Aids” within AAABCs on approach? (3)
- DH/DA
- NAV Page/CDI needles
- PRI/STBY frequencies
For an RNP, how do you identify a fly past vs a fly over way point?
Fly past = 4 pointed star
Flow over = 4 pointed star surrounded by a circle
