¶ Introduction
The Case 3 recovery is used at nightime or when weather prohibits the Case 1 overhead stack AND weather prohibits the Case 1 pattern (LINK see Case 1 Recovery). The Case 3 invovles a marhsal stack that is higher and farther from Mom than the usual Case 1 overhead stack. From the stack, you will shoot an instrument approach (the CV-1 Approach) using the TACAN and then ICLS to get to the ball and land.

¶ Terminology
| Term | Definition |
|---|---|
| DME | Distance Measuring Equipment. When given as an instruction 301 marshal on the 180 radial, 21 DME , this is requesting that you marshal on an orbit that starts at 21nm away from the boat, as measured by your onboard navigation equipment |

¶ Radio Communications
Within 50 nm of the boat:
301: “Marshal, 301, marking mom’s 270 for 45, angels 15, state 8.0”
Marshal: “301, Marshal, case 3 recovery, CV-1 approach. Altimeter 29.92, final bearing 330. 301 marshal on the 180 radial, 21 DME, angels 6, expected approach time 20.”
301: “301 marshal 180 for 21, angels 6, time 20.”
In this example, once established near the marshal radial on altitude (6,000 feet MSL with the correct altimeter):
301: “301, established, angels 6, state 7.5”
Marshal: “301, Marshal, roger.”
At time XX20 or when manually pushed by approach:
301: “301, commencing, altimeter 29.92, state 7.0”
Passing 5,000 feet AGL (RADALT set to 5k, going off):
301: “301, platform”
Fly the rest of the CV-1 approach. At 3nm from the boat, intercept ICLS glideslope to start descending. At 0.8nm, call the ball.
301: "301, Hornet ball, 4.2"
Paddles: "Rooger ball"
¶ Flying the Case 3
- Maintain 250 KCAS from holding all the way through the approach.
- Fly radar altitude unless you’re above 5000 (i.e. in holding) Make sure your altimeter is correct.
- Once you begin the approach from holding, throttles idle, speedbrake out, and nose down to maintain 250 knots and -4000 fpm descent rate.
- At platform (5000 feet), speedbrake in, nose up to arrest descent rate to at least -2000 fpm and throttle as needed for 250 knots.
- At 20nm, you will turn from your marshal radial toward the final bearing courseline (you will need to adjust your courseline in order to manage this correctly)
- You need to intercept the final bearing courseline before 12nm.
- If you hit 12 first, you need to put the TACAN at your 3 or 9 o’clock to stay at 12nm until you hit the courseline and turn back inbound.
- Meanwhile, level off at 1200 feet AGL. Once you hit 9 DME on the inbound final bearing, slow down slightly and configure (gear, full flaps) and trim to on-speed.
- At 3 DME, intercept ICLS glideslope and descend until you see the ball.
- When you’re stopped on the deck, throttle back and turn your lights off! (L key by default)
¶ Bolter / Waveoff
- If for whatever reason you hook skip all 4 wires, climb back up to 1200 feet straight ahead. Raise your gear, flaps to HALF. Fly 200 knots. Once you’re at 1200 feet, turn left to reciprocal (aka downwind).
- You need to be 2nm abeam the ship, so wider than usual for case 1.
- Once your TACAN reads 4nm, you can turn inbound. Look for traffic on final and give them the right of way.
- If you turn at 4, gear and flaps down immediately. If you turn at 6, configure halfway through your turn. If you turn at 8 or later, configure when you’re established back on the final bearing.

¶ Case 3 Qualification Rubric Items
These are the rubric items that are used by proctors during the C3 qualification:
- Correct initial check-in with Marshal, aircraft lights on, hook down
- Readback correct or easily corrected
- Push time checked and rejected if too soon
- Called “established” once on assigned altitude, near marshal stack
- Correct altitude and position while holding
- Commenced at push time, correct call and airspeed
- Began descending immediately
- Turned away from marshal radial toward EFB at 20 DME
- Checked in with approach no sooner than 15 seconds after switching
- Called platform at 5k (can be combined with check-in)
- If not on EFB by 13 DME, turned to 12 DME arc until EFB
- Leveled out at 1200 AGL
- Intercepted EFB
- Configured at 8-9 DME (instruct to raise hook now for T&G)
- Called the ball when instructed
- Touch and go or own waveoff
- Climb straight ahead to 1200 AGL no faster than 200 knots
- Turned for downwind at 4 DME if not instructed otherwise
- 2 DME abeam call
- Turned for final at 4, 6, or 8 DME
-> Gear down, flaps full immediately if turning at 4
-> Gear down, flaps full halfway through the turn if at 6
-> Gear down, flaps full on final if turning at 8

¶ Key Takeaways
¶ Memory Recall Items
The following items should, ideally, be practiced until they can be completed from memory only:
| Task | Description |
|---|---|
| Radio Phraseology | Checkin call, Established call, Commencing call, Approach checkin, Platform |
| Speed Values | Know the speed limits, and which speed you should be flying when |
