while advancing the throttles to MIL or MAX. Do not over-rotate.
An in-close or late waveoff, coupled with an over-rotation can lead to an
in-flight engagement, which can severely damage the aircraft.

8.3 ACL MODE 1 AND 1A APPROACHES
A typical Mode 1 and 1A approach is shown in figure 8-4. The Mode 1/1A approach does not require
ATC, but ATC should normally be used. The following procedure is typical for a Mode 1 (1A) approach
from marshal to touchdown (or ½ mile).
1. Request a Mode 1 or Mode 1A approach from Marshal.
2. HSI format - SELECT (box) ACL
When the ACL option is boxed, the LINK 4 format automatically appears on the LDDI, and the
ACL mode automatically starts its self test. At this time, the ILS, data link, and radar beacon are
automatically turned on (if not previously on), and IBIT is run on the data link and radar beacon
systems. Also, the uplinked universal test message is monitored for valid receipt.
3. LINK 4 format - CHECK FOR ACL 1
Mode 1/1A capability is not available if ²ACL 1² is not displayed.
4. Report departing marshal - ²SIDE NUMBER, COMMENCING²
5. Normal CCA - PERFORM
Descend at 250 KCAS and 4,000 fpm to 5,000 feet, (platform) then reduce rate of descent to 2,000
fpm. When selected, ILS steering is automatically displayed on the HUD once valid signals are
received and must be manually deselected, if the symbology is not desired.
a. At 5,000 ft MSL, report - ²SIDE NUMBER, PLATFORM²
b. Continue descent to 1,200 ft MSL.
c. At 10 nm, report - ²SIDE NUMBER, 10 MILES²
6. LDG GEAR handle - DN (at 10 nm but NLT 8 nm)
7. FLAP switch - FULL
NOTE
Coupling to ACLS commands in HALF flaps is possible; however, the
ACLS program has not been optimized for approaches using HALF
flaps. All mode 1/1A approaches should be performed with FULL
flaps.
8. Landing checklist - COMPLETE
a. Check the LDDI for ID LT indication.
9. Slow to approach speed at 6 nm.
10. ATC - ENGAGE

III-8-14 ORIGINAL
11. RALT hold mode - ENGAGE (if desired)
ACL acquisition occurs at approximately 3.5 to 8 nm and is indicated by ²ACL RDY² on the LINK
4 format and the data link steering (TADPOLE) on the HUD. It is desired but not required, to have
ACL coupled at least 30 seconds before tipover. T/C is replaced by MODE 1 on the LINK 4 format.
After ACL Acquisition -
12. Report needle position - e.g., ²up and on² or ²up and right².
For Mode 1, when directed -
13. CPL option - SELECT on UFCD
If T/C is engaged, press CPL once to uncouple T/C then press CPL again to couple ACL. When
the aircraft is not coupled, ACL RDY is displayed on the HUD. ACL couple is indicated by CMD
CNT and MODE 1 on the LINK 4 format and CPLD P/R on the UFCD and HUD. At this time,
the uplinked command displays of heading, airspeed, altitude, and rate of descent are removed
from the LINK 4 format and the HUD.
14. When coupled, report - ²COUPLED²
15. When aircraft responds to automatic commands, report - ²COMMAND CONTROL²
For Mode 1A Approach -
16. Downgrade to Mode 2 at ½ mile by
a. Paddle switch - PRESS
b. ATC button - DISENGAGE (if desired)
17. Report - ²SIDE NUMBER, STINGER, BALL or CLARA, FUEL STATE, AUTO² (if ATC
engaged).
For Mode 1 Approach -
11. Report - ²SIDE NUMBER, STINGER, BALL or CLARA, FUEL STATE, COUPLED².
12. At approximately 12.5 seconds before touchdown, the uplinked ²10 SEC² cue is displayed on the
LINK 4 format and the HUD.
13. After touchdown, ACL and ATC should be automatically disengaged.
NOTE
After Mode 1 or 1A downgrade or touch-and-go, actuate the paddle
switch to ensure complete autopilot disengagement.

8.4 ACL MODE 2 APPROACH
A typical ACL Mode 2 approach is shown in figure 8-5. For a Mode 2 approach, the HUD data link
steering is used to fly a manual approach.
1. HSI format - SELECT (box) ACL
When the ACL option is boxed, the LINK 4 format automatically appears on the LDDI, and the
ACL mode automatically starts its self test. At this time, the ILS, data link, and radar beacon are
automatically turned on (if not previously on), and IBIT is run on the data link and radar beacon
systems. Also, the uplinked universal test message is monitored for valid receipt.
2. LINK 4 format - CHECK FOR ACL 1 or ACL 2
Mode 2 capability is not available if ²ACL 1² or ²ACL 2² is not displayed.
