What are clearances designed to do?
Deconflict IFR aircraft in the NAS
What should you have prior to contacting clearance delivery?
Weather and ATIS Information Code
How should you readback a clearance?
In the same sequence it was given
Prior to an ITO, within how many degrees of runway heading should the heading indicator be?
5 Degrees
Once vectored off an ODP is it considered cancelled?
Yes. Assigned altitude must be higher than the MVA
Unless specified otherwise, obstacle clearance is based on the aircraft crossing the DER at least
35 feet above the DER
0 feet for USAF and USN
Before making an initial turn how high do you need to be in order to maintain obstacle clearance?
400 feet above the DER
To maintain obstacle clearance, what is the standard minimum climb gradient required until the minimum IFR altitude?
200 feet per nautical mile
ODPs can be published textually or graphically while SIDs are always published
graphically
4 Types of ODPs
ODPs make me nervous (NRVS)
N - Non Standard Takeoff Mins
R - RTRL (Reduced TO Rnwy Length)
V - VCOA (Visual Climb Over Airport)
S - Specific Routing
Which ODP requires you to takeoff prior to a specified distance from the end of the runway?
RTRL
Do SIDs provide obstacle clearance?
Yes, however they are not ODPs
If ATC issues an altitude during a SID do you continue to fly the lateral guidance and speeds?
Yes
If ATC vectors you off a SID, is the SID cancelled?
Yes
What is a Diverse Departure?
Turn whatever direction you want after reaching 400 feet above the DER and maintaining 200 feet per NM climb until min IFR altitude (must be AT LEAST 35 feet above DER at DER)
How far from the airfield is a Diverse Departure good for?
25 NM (non-mountainous)
46 NM (mountainous)
Does a diverse departure procedure clear aircraft from low close in obstacles from NOTAMs, Takeoff Minima and DPs?
No, conflicts must be identified individually
What is a Diverse Vector Area?
an area where ATC may provide random radar vectors during an uninterrupted climb from the departure runway until above MVA or min IFR altitude
Where can you find a DVA?
Trouble T section
Can DVAs have a higher climb gradient than 200 fpNM?
Yes it will be published
Do IFR DPs provide clearnace for low close in obstacle? (TAKEOFF OBSTACLE NOTES)
No. None do. Not even ODPs.
What are the 7 types of DPs?
DODMASS
Diverse Departure Area
ODPs
Diverse Vector Area
MAJCOM Specific Training
ATC Instructions
SIDs
Special Departures
Once vectored off an ODP, is it cancelled?
Yes. (Cannot be vectored until above the MVA/min IFR alt)
What altitudes are victor routes flown?
Below 18,000 MSL
What altitude block are jet routes flown at?
FL180-FL450
What does a flag with an X indicate?
MCA (Min Crossing Altitude)
What are Tango Routes?
RNAV Routes flown with GPS from 1200 to FL180
What are Q routes?
RNAV Routes flown using GPS from FL180 to FL450
Which number is the top number along a route?
MEA (Minimum Enroute Altitude)
Which number is the bottom number along a route with an asterisk?
MOCA (Minimum Obstacle Clearance Altitude)
What does the MEA ensure?
acceptable navaid reception and 1000 feet of obtacle clearance (2000 feet in mountainous terrain)
What does the MOCA ensure?
1000 feet of obstacle clearance (2000 feet in mountainous terrrain) but only guarantees signal 22 nm from the NAVAID
What does a flag with an R in it indicate?
MRA (Minimum Reception Altitude)
In the absence of a changeover point, when do you change to the next NAVAID? (Straighline)
At the midpoint of the total straightline distance between the two NAVAIDS. (not necessarily a fix)
In the absence of a changeover point, when do you change to the next NAVAID? (Bend)
At the fix where the line bends
What is the OROCA?
Off Route Obstacle Clearance Altitude (similar to a maximum elevation figure on a VFR chart) 1000 feet clearance (2000 feet mountainous) may not provide NAVAID reception
What is the preferred method of filing a flight plan?
DD 1801
When an ODP says ‘std’ what is ‘std’?
lowest compatible approach minimums
What is CRAFT?
Clearance Limit
Routing
Altitude
Frequency
Transponder
Why is IFR clearance necessary?
To deconflict IFR in the NAS
When should you expect an ITO?
Night, Snowy, Desert, Water
Is it required to readback CRAFT on the ground?
No. All airborne clearances MUST be readback
When can you turn off runway heading?
200 fpNM
400 feet above DER
at least 35 feet over DER
140 KIAS (T6 only)
