Flashcards — IRA-H Area III ATC Clearances & Procedures (Lessons 06–07)

CLEAR
What does CRAFT stand for?
Clearance limit, Route, Altitude, Frequency (departure), Transponder (squawk).
CLEAR
Which CRAFT items change most often?
The departure Frequency and the Transponder code — copy them carefully; route is often "as filed."
CLEAR
Why read back the whole clearance?
So ATC confirms what you heard matches what they intended — catches errors before you fly them.
CLEAR
Clearance void time — what if you're not off in time?
Clearance is invalid; remain on the ground and advise ATC. If unable to reach ATC, you may not depart IFR.
DP
ODP vs. SID?
ODP = obstacle clearance, may be flown at pilot discretion unless assigned. SID = ATC-assigned routing that also clears obstacles.
DP
What does a climb gradient (ft/NM) require of you?
Convert to ft/min at your groundspeed and confirm your aircraft can meet it before accepting the departure.
HOLD
Three holding entries?
Direct, parallel, and teardrop — chosen by inbound heading relative to the pattern (70° rule separates parallel/teardrop).
HOLD
Standard hold — turns & inbound leg time (≤14,000 ft)?
Right turns; inbound leg timed to 1 minute (1½ min above 14,000 ft).
HOLD
Wind correction on the outbound leg?
Triple the inbound drift correction outbound to produce a 1-minute inbound leg on the pattern.
HOLD
What is EFC and why track it?
Expect-Further-Clearance time — your lost-comm reference and a fuel-planning anchor while holding.
RISK
Biggest ongoing risks in a hold?
Drifting out of protected airspace and burning fuel — fly precise headings/timing and watch endurance.
R44
Where do hold/departure performance numbers come from?
R44 POH performance & fuel-flow sections for endurance/climb. R44 is normally VFR-only — verify IFR use.
