When ATC says “Cleared To ___” that is also known as your ___
Clearance Limit
On an IFR clearance in VMC, are you responsible for “see and avoid” traffic?
YES
When are IFR clearances required?
- Class A (91.135)
- Before operating IFR in CONTROLLED AIRSPACE - must file IFR FP and RECEIVE CLEARANCE (91.173)
- When departing VFR and expecting to become IFR - you can pick up clearance in the air, but you must be able to maintain VFR until clearance delivery
What regulation enables pilots to decline IFR clearances?
91.123
If a pilot declines an IFR clearance given by ATC, what must they do?
REQUEST AN AMENDED CLEARANCE!!!! Ex: “Unable to turn right due to thunderstorm, but we can turn left”
What regulation requires you to file an IFR flight plan?
91.173
What regulation tells what you need to include in an IFR flight plan?
91.169
Where can you get clearance at an CONTROLLED airport?
Clearance Delivery, Ground, Tower
Where can you get clearance at an UNCONTROLLED airport?
Controlling Agency, RCO, GCO, FSS, or the National Clearance Delivery phone number (888-766-8267)
In practice, an IFR clearance is available __ minutes prior to the proposed departure time
30 minutes
Describe a Pre-Departure Clearance (PDC)
- When clearance is transmitted directly to the ACARS unit on the flight deck in text format
- No voice communication is used unless there is a question or problem
What are the 2 types of IFR Departures?
SIDs: Standard Instrument Departure (2 Types)
ODPs: Obstacle Departure Procedure
What are the 3 ways to start an IAP?
- IAF (Initial Approach Fix)
- Feeder Route/Transition - Provides guidance to an IAF
- Vectors (Limited to Radar Vectors)
What does No PT indicate?
No Procedural Turn is expected or required
What is a Clearance Void Time?
- The time your a/c must be airborne by or else the clearance/release is no longer good
- If you decide not to takeoff after receiving a CVT and do not contact ATC, they will assume you crashed since they will not have heard from you and send search and rescue
What does it mean if you are “Holding for Release”
You can get your clearance, but you cannot leave!
What are the 2 main objectives to the IFR system?
- Don’t hit other IFR traffic
2. Don’t hit terrain/obstructions
If a special minimum is NOT published for any given airport, which reg. do we refer to? What does it specify?
91.175(f)
1 and 2 engine a/c: 1sm
3+ engine a/c: 0.5sm
Helo: 0.5sm
Will ATC clear you for an ODP?
No! It’s you’re responsibility to comply with an ODP if one is published
When will an ODP be published?
When something penetrates the 152 ft/NM (40:1) obstruction slope
Describe a Standard IFR Departure
- Fly runway heading until 400’ AGL
- Turn on Course
- Maintain a climb gradient of 200 ft/NM
(GS/60=VSI/ft/NM)
What is the biggest difference between ODPs and SIDs?
- ODPs are NOT assigned by ATC
- SIDs are an ATC-requested and developed departure route
CRAFT/CRADS
Clearance Limit Route Altitude Freq./Departure Freq. Transponder/Squawk
Expected Departure Clearance Time (EDCT)
ATC will assign a runway release time in which you must depart within +/- 5 minutes
