MT 2 Flashcards
How to fly a VOR Approach:
Simply fly it as if it were an RNAV approach, but have the preview needles displayed.
NOTE: You will need to manually enter the frequency/course. No auto-tune for VOR.
NOTE: Missed approach if 1 dot deflection on preview needle once aligned with final approach course.
Speed requirement for a procedure turn
200 knots
If a VOR approach does not have a FAF (such as an on field VOR), what is considered the FAF?
The FAF becomes the point at which you intercept the final approach course inbound.
What approach category is the ERJ-175? Can we fly anything different? What speeds are associated with the approach categories we can use?
- ) ERJ-175 is certified as CAT C. (So even if you might be flying a really slow approach speed like CAT B, you must use CAT C.)
- ) We can fly CAT C and D. So if your speed requires CAT D, use CAT D mins. But nothing less than CAT C.
- )
- CAT C: Final approach segment speed of 121 - 141 knots
- CAT D: Final approach segment speed of 142 - 165 knots
How do you set an MDA in the minimums?
- If the approach does not have a ballnote, set published MDA plus 50’ (derived decision altitude)
- If the approach has a ballnote (only authorized operators may use VNAV DA(H) in lieu of MDA (H)) then set the actual MDA (rounded up to nearest 10’ increment as you usually would).
OpsSpec C073 lets us use an MDA as a DA if there is a ballnote. Can this authorization be used on LOC approaches?
No, do not ever use this on a LOC approach. Always round up to the nearest 100’ increment and set that in the minimums and also altitude preselect.

No, do not ever use this on a LOC approach. Always round up to the nearest 100’ increment and set that in the minimums and also altitude preselect.
On a missed approach, what speed does GA in the vertical mode command?
All engines operating: Vref + 20
Single Engine: Vac
When must you use temp comp?
- ) If the airport info 10-7 page has a “Cold Temp Airport” blue bar, temp comp is required if the temp is below this temperature listed. (ALL APPROACHES)
- ) If on a specific approach plate, the remarks section gives temperature limitations, and the temp is outside those parameters.
- ) At all foreign airports for all approaches whenever OAT is less than -30 degrees C.
You must advise ATC that you are temp comping. What are you required to tell them?
The altitude required at both the IAF and the MAHP.
Ex. “SKW5435 requires 9,400’ at ADANE (IAF) and 9,400’ at DRAKE (MAHP) for cold weather operations.”
When is an RNP discontinue procedure required?
If the approach has an RF leg in the final approach segment
Describe the RNP discontinue procedure
- ) Callout “Discontinue”
- ) Deselect APP
- ) MAN speed 165 knots
- ) Set missed approach altitude and FLCH
(PM sequences the missed approach in the FMS)
- ) Call “missed approach flap 2” -positive rate- “gear up”
- ) Passing runway waypoint: “speed up clean up” (as always, no SOPM guidance. So at this point, I would ASSUME it is OK to select manual speed 200 and call “climb sequence after takeoff checklist” but who knows what the instructor wants…..
If the autopilot fails on an RNP Approach, is it ok to continue? What are some things that require a missed approach on an RNP?
It may be the safest thing to do- just continue to land.
Things that require a missed (just a few):
- Yellow flags for altitude miscompare (greater than 100’)
- “NO RNP” or “DGRAD” EICAS messages
On an RNP approach, there is always a risk of a total navigation failure and therefore you should have a contingency plan. What should that plan be?
- ) Initially just maintain your heading or current bank
- ) Have a cardinal direction that is the best direction for avoiding terrain. e.g. “West is the ocean so lets just fly west and climb”
- ) Have PM declare an emergency and get vectors as soon as possible
Regarding an RNP approach, what do failures such as a dual FMS failure, GPS POS DISAG, and FMS POS DISAG all have in common? What should you do?
The thing they all have in common is that they all make your position unreliable/unknown. This is bad news on an RNP approach.
Big takeaway: These types of failures require a CONTINGENCY procedure, not a missed/discontinue like many other failures.
