IR.III.A.K1 — elements of an IFR clearance (CRAFT) IR.III.A.S1 — copy, read back & comply with a clearance IR.III.B.K1 — ODPs, SIDs & obstacle/terrain protection IR.III.A.R1 — risk: clearance ambiguity / readback errors

⚑ FLAG (Walter): confirm exact Task/code lettering in the current FAA-S-ACS-8 — older editions placed Departure under III.B; verify the helicopter applicability notes apply unchanged.

IFR Clearances & Departure Procedures

Copy it, read it back, comply — and leave the ground on a route that keeps you off the rocks.

By the end of this lesson you can:

Copy a full IFR clearance using the CRAFT shorthand and read it back correctly.
Explain what a clearance limit, void time, and "expect" altitude mean.
Distinguish an ODP from a SID and know when each provides obstacle protection.
Recognize the climb-gradient and visibility assumptions that depend on your aircraft's performance.

1 · Copying the clearance — CRAFT

An IFR clearance is read in a fixed order, so you can pre-format your kneeboard with CRAFT: Clearance limit (usually your destination), Route (often "as filed," but be ready for an amendment), Altitude (initial altitude plus an "expect" higher altitude and a time), Frequency (departure), and Transponder (squawk code). The squawk and frequency are the unpredictable parts — copy them carefully. Always read back the full clearance so ATC can confirm what you heard matches what they intended.

2 · Void times & release at non-towered sites

Departing IFR from an airport without a control tower, you will typically receive a clearance void time ("…clearance void if not off by…") and often a time to call for release. If you do not depart by the void time, you must advise ATC, and if you cannot reach them, the clearance is no longer valid — you must remain on the ground. Brief your taxi and run-up timing against the void time so you are not rushed.

3 · Departure procedures — ODP vs. SID

Departure procedures keep you clear of terrain and obstacles until you reach the en route structure. An Obstacle Departure Procedure (ODP) is designed solely for obstacle clearance and may be flown without an ATC clearance to do so (unless ATC assigns otherwise); ODPs are published textually and sometimes graphically. A Standard Instrument Departure (SID) is an ATC-convenience routing that also provides obstacle clearance and is always assigned by ATC. Both assume you can meet a required climb gradient (in feet per nautical mile) to a specified altitude — translate that into a feet-per-minute climb at your planned groundspeed and confirm your aircraft can achieve it.

Your aircraft: a climb gradient is published in ft/NM; your POH gives a rate of climb in ft/min. Convert using your planned groundspeed before accepting a departure.

✍️ Fill in for the aircraft you fly Best rate-of-climb speed and the rate of climb you can sustain on a standard day — look it up in the R44 POH Section 5 (Performance) / Section 4 (Normal Procedures) and confirm with your CFI.

⚑ FLAG (Walter): the Robinson R44 is normally certificated for VFR only and is not approved for IFR flight — confirm how this lesson should frame "departure" for an aircraft used in a simulator / IFR-approved trainer for the rating. Verify any R44 IFR-equipment statements against the actual POH.

Risk management (the “Consider”): the highest-risk moments are a misheard or mis-read-back clearance and accepting a departure climb gradient you cannot actually make on a hot/high day. If any element is unclear, ask ATC to "say again" rather than guess. Brief the ODP/SID, the void time, and your achievable climb before you pull pitch.
