JOINT ADVANCED MULTI-ENGINE T-44A
visually check your radial/DME on the approach plate or enroute chart. If required, make a timed turn
to the reciprocal, rotate the course set knob until the CDI centers with a TO indication, and fly direct to
the station maintaining course using the RMI needles in conjunction with the CDI. At station passage,
make a timed turn to the desired intercept heading, rotate the course set knob to the FAC and track the
outbound course using heading information supplied by the co-pilot. Accomplish the course reversal
using timed turns. When the CDI starts to center commence another 15 second timed turn to final.
Two methods used to track inbound/outbound are:
Method 1. Check the tail of the needle to determine present radial. Visualize the radial, and DME if
available, to determine your position on the approach plate. Turn in the direction required for course
intercept. Make timed turns to maintain the FAC.
Method 2. Set the CDI and heading bug to present a graphic display of FAC and present heading.
Ask the CP for heading calls (off the wet compass) and set the bug on the corresponding
Utilize the CDI set to the FAC (radial to intercept).
You now have a cockpit presentation of your heading, final approach course (radial to
intercept), and required direction to turn (intercept angle) to return to course.
Configure the aircraft at the normal point and continue the approach using NH procedures.
3. ILS/LOC No Heading Approach. An ILS or LOC approach is possible with no heading information
either by utilizing radar vectors to final or by executing a procedure turn if the IAP contains a LOM
(locator outer marker; an NDB aligned on course centerline). If radar vectors are not available, proceed
direct to the LOM using NDB no heading techniques. At station passage, make a timed turn to the desired
intercept heading, rotate the course set knob to the FAC and track the localizer course outbound using
heading information supplied by the co-pilot and techniques discussed above for CDI tracking. NDB
information (NH) will also be available and can be used throughout the procedure turn to maintain SA and
accomplish the course reversal using NDB NH techniques. In either case, when the localizer "becomes
alive" and starts to move off full deflection, commence a timed turn to final. Once established inbound on
the localizer and at the proper altitude, track the localizer and glideslope as in a normal ILS or LOC
approach using guidance from the needles/CDI. Configure the aircraft as previously discussed.
F. CDI Failure (VOR, TAC).
If the CDI fails, or is found to be out of tolerance during an instrument check, the following procedures
VOR. A VOR approach can be flown using the needles on the RMI. Use the "RMI only" techniques
described in section 404 and used on all normal NDB approaches. Remember, the needle will always
point to the station, the head of the needle will always "fall" and the tail of the needle will always
TACAN. TACAN approaches can be flown using just the bearing pointer and "tail" on the HSI. The
"RMI only" techniques above will be applied using the HSI. Under these circumstances, the following
techniques may be helpful:
Inbound Course Intercept. A common technique to use when intercepting a course inbound is to put
the heading bug on the inbound course; the pointer will "fall" to the heading bug when on an intercept
heading. The intercept is completed by turning to put the pointer under the upper lubber line.
Maintain course by keeping the pointer centered on the heading bug.
Outbound Course Intercept. When intercepting a course outbound, the heading bug is put on the
outbound course; this time, the "tail" will "rise" to the heading bug when on an intercept heading.
Turning to put the heading bug and the "tail" under the upper lubber line completes the intercept.
Maintain course by keeping the "tail" centered on the heading bug.
G. Visual Approach.
Visual approaches reduce pilot/controller workload and expedite traffic by shortening flight paths to
the airport. A visual approach is conducted on an IFR flight plan and authorizes the pilot to proceed
