IFR Departure Procedures Flashcards
SID
Standard Instrument Departure
TC
Transport Canada
AIM
Aeronautical Information Manual
What part of the AIM specifically applies to IFR procedures
Rules of the Air (RAC) section
CAP
Canada Air Pilot
What part of the CAP specifically applies to IFR?
The General Section (CAP GEN)
What is the determinant of IFR departure
Visibility governs IFR Departures.
What is standard departure visibility?
1/2 Statute Mile (SM) or 2600 RVR
Is it possible to depart with reduced visibility?
Yes, but only with special air crew and aircraft and operational procedures.
Define Govern
Legal authority to limit, forms the basis’s for violations and enforcement under the CARS.
What to do when we don’t have the visibility?
Don’t depart
We only care about ____ and not ____ for a legal departure
Visibility, ceilings
Visibility Order of Precedence
- Runway Visual Range (RVR)
- Aerodrome Ground Visibility (as reported by trained observer)
- Vis as determined by PIC
Most accurate means to measure visibility
Runway Visibility Range (RVR), read in feet
RVR Limitations
Only valid for a single runway (not the runway at the opposite end of the concrete)
Might be fooled by local phenomena like blowing snow.
RVR becomes not governing when subject to fluctuations or local phenomena.
RVR is discarded when:
Airport Ground Visibility is at or above the required min.
Airport ground visibility is determined
Trained observers like ATC, FSS, air operator radio station, or
AWOS station
AWOS
Aerodrome Weather observing station 
PIC can only take authority to determine visibility when
There is no RVR
AND
There is no ground visibility report
Departure Summary
You can go if (one of these visibilities are okay):
- RVR is okay
- Ground Visibility is OK (because now RVR doesn’t matter).
- If no RVR or aground Visibility Reported and OIC determines visibility
ATC/FSS/CARS will advise you when visibility is governing (True / False)
True, they will tell you and you aren’t likely to get an ATC takeoff clearance if below minimums.
FSS or CARS can’t stop you from taking off, but they are likely to advise against it.
How do we know if RVR is available?
It appears in METAR when at or below 6000 feet (along with trend)
Aerodrome chart will also show you.
ATC/FSS will include in the ATIS and likely in voice advisories.
RVR may be designated as (describe letters and location)
RVR A - runway threshold
RVR B - at runway midpoint
RVR C - rollout portion at end of runway and is VERY rare
Obstacle Clearance for IFR Departures assume:
- Aircraft cross runway end at minimum of 35 feet AGL
- Climb straight ahead to 400’ AAE before making any turns
- Maintain climb gradient of 200’ per nautical mile until reaching MEA for en route.
AAE
Above aerodrome elevation
MEA
Minimum en route altitude
MOCA
Minimum obstacle clearance altitude
S
How is climbing gradient expressed?
Feet per nautical mile
What information do we need to calculate climb gradient?
Ground speed and rate of climb
How do we convert climb gradient to feet per minute?
Use chart or ____ function on CXE
What is GESR’s rate of climb at 90 kts GS to maintain 200 feet per nautical mile climb gradient?
300’ per minute
With regards to climbing gradients, what might the aerodrome chart show other than 200 feet/ nautical mile?
- A climb gradient greater than 200 ft./min.
- Shuttle procedures in mountainous terrain.
- Visual climbs.
SPEC VIS
Special Visibility Procedure - the note explaining a climb visually to a safe altitude (based on aircraft speed).
May require a ceiling height.
When determining the visibility required for SPEC VIS . itwill depend on
Aircraft Category
Aircraft Categories maneuvering speeds:
A - up to 90 kts
B - 91 to 120 kts
C - 121 to 140 kts
D - 141 to 165 kts
E - 165 kts +
Required departure Visibility for each category of aircraft
A - 1 sm
B - 1 1/2 sm
C, D, E - 2 sm
SID
Standard Instrument Departure
Route Clearance in Controlled airspace is normally obtained prior to departure from:
FSS on MF or via Remote Communication Outlet (RCO)
Clearance Delivery / Ground Control
ATC PAL station
FSS
Flight Service Station
RCO
Remote Communication Outlet (for a Flight Information Centre)
ATC PAL
ATC unit close enough (peripheral) to get clearance on the ground.
IFR clearances and amendments must be read back and full with the exception of:
When a clearance is received on the ground before departing a controlled Aerodrome and include an SID.
Then, the pilot only needs to acknowledge with the aircraft call sign and transponder code
If not on the ground, and IFR clearance may come in flight from:
An ATC unit or FSS
To generate an IFR clearance,
File an IFR flight plan.
IFR flight plans are the same as VFR flight plans except
 they must include an alternate airport
And pilots should consider any mandatory routes contained in planning section of CFS
How long does the AIM recommend you file an IFR plan prior to departure.
30 min (but it’s actually much faster these days with electronic submissions)
Seven elements of an IFR Clearance:
- Call sign
- Clearance Limit (denoted by the word “To”)
- Route (Via)
- Altitude (Maintain)
- Departure Runway and Transition (Depart)
- Transponder Code (Squawk)
- ATC Frequency (Contact)
Void time
You must depart prior to or at the void time or receive a new clearance (usually from an uncontrolled airport)
What does ATC need to know after take off?
Call sign
Altitude we are vacating
Altitude we are climbing to
(or altitude we are maintaining if already in level flight)
Do we need to maintain a listening watch on the mandatory frequency even after being instructed to switch frequencies?
Yes.
What to do if your departure is delayed at an uncontrolled airport?
There is a 60 minute departure window to make contact.
You must update departure time by contacting FSS or Area Control Centre by telephone.
Can you depart when RVR is fluctuating between 1300 and 2600?
No. The lowest RVR value dominates.
With regard to SPEC VIS, does ground speed matter?
No. Even if you have a wind speed directly on the nose that reduces your GS by 50 knots, the Aircraft Category climb speed is all that matters for Visibility requirements.
