TASK 1078

TASK: Perform unusual attitude recovery.

CONDITIONS: In an AH-64 helicopter with a UT, an IP, or an IE and under simulated IMC or in an AH64CMS.

STANDARDS:

DESCRIPTION:

NOTE: If operating in the NOE approach or manual stabilator mode, reset to automatic.

NVS TECHNIQUES: Simulated or actual IMC is not a prerequisite for an unusual attitude. During NVS operations, the P* may experience an unusual attitude even though he has visual reference with the earth's surface. He also may experience an unusual attitude when he loses visual reference as a result of FLIR image degradation, DC restoration, or sensor failure. Crew coordination during the recovery should be preplanned and prebriefed to conform to the flight condition (day or night) and to the P'scapability to assist. If an unusual attitude is encountered, the method of recovery used varies according to the symbology mode, type of unusual attitude, and the flight parameters. If hover or bob-up symbology is being used, unusual attitudes will probably involve excessive sink rates during OGE hovers or masking procedures. This is sometimes combined with undesirable rearward drift.

CAUTION

To prevent the possibility of overtorquing the engines, avoid excessive or rapid power application.

TASK 1083

TASK: Perform or describe inadvertent IMC procedures/VHIRP.

CONDITIONS: In an AH-64 helicopter under simulated IMC, in an AH64CMS, or orally in a classroom environment.

STANDARDS:

DESCRIPTION:

NOTE 1: If the stabilator is in the manual or NOE approach mode, reset it to automatic.

NOTE 2: Use of the doppler as an IFR navigational system is not authorized; however, the crew should consider and plan for its use as an emergency backup system.

NIGHT OR NVD CONSIDERATIONS: When using the NVS or NVG, the crew may be able to see through thin obscurations, such as fog and drizzle, with little or no degradation. The NVG should be removed or flipped up once cruise flight is established.

NVS TECHNIQUES: When IMC are encountered, the crew may use the HDU, VDU (PLT), HOD (CPG), or aircraft instruments to initiate inadvertent IMC procedures or VHIRP. The preferred method is to use the aircraft instruments. However, if HDU, VDU, or HOD is used, whiteout or brownout may be encountered and symbology may be obscured. If this happens, immediately move the PLRT/BRSIT switch to the PLRT position and reverse polarity. Then select the appropriate symbology mode (transition or cruise), and perform the procedures described above. Once the climb is established and the aircraft is clear of the immediate terrain, make the transition to the aircraft instruments.

NOTE 1: Aircraft trim indications are available to the CPG only through flight symbology.

NOTE 2: Inadvertent IMC may be encountered in environments where obscurants such as sand, dust, snow, rain, and smoke are present.

TASK 1090

TASK: Perform masking and unmasking.

CONDITIONS: In an AH-64 helicopter or an AH64CMS, with the hover power check completed, while not engaging a target.

STANDARDS:

DESCRIPTION:

NOTE 1: When unmasking the helicopter, the crew should select a new location that is a significant distance from the previous location and where the target area can still be observed. If the target area is a long distance (2,000 to 3,000 meters) away, moving only 100 meters will still keep the aircraft in the same field of view from the target. However, if the target area is close to the unmasking position, a drift of 100 meters will make a significant difference.

NOTE 2: Hover OGE power is required for masking and unmasking.

NOTE 3: Use of the HAS will reduce the P*'s workload.

NIGHT OR NVD CONSIDERATIONS: Maintaining altitude and position is more difficult when hovering above 25 feet without aircraft lights. The P* should use the radar altimeter to assist in maintaining altitude. He should use the position box to assist in maintaining aircraft position. Otherwise, he must use references such as lights, tops of trees, or man-made objects above and to the front and sides of the aircraft. By establishing a reference angle to these objects, the P* can detect altitude changes by changing his viewing perspective. Hovering near ground features, such as roads, provides ideal references for judging lateral movement. However, the P* may become spatially disoriented when alternating his viewing perspective between high and low references. Therefore, he must rely on the P for assistance if he becomes disoriented.

NVS TECHNIQUES:

NOTE: If doppler drift exists, the time spent in bob-up may increase the error in the position symbology. Predicting DNS drift is difficult. The P* must base his decision to descend on image-oriented references. He can use position symbology information to enhance aircraft position control. However, the use of symbology alone will not ensure obstacle avoidance.

TASK 1105

TASK: Perform IHADSS operations.

CONDITIONS: In an AH-64 helicopter or an AH64CMS with IHADSS boresighting and IHADSS video adjustments completed.

STANDARDS:

DESCRIPTION:

NOTE: When the CPG selects the HMD or HMD/TADS mode initially, the selected ACQ SEL source will automatically provide cueing without further action by the CPG.

NOTE: If the IHADSS BRSIT switch is on, the BRU LOS, rather than the IHADSS LOS, will be sent to the FCC for the PLT or the CPG.

NOTE 1: For all subsequent changes in the ACQ SEL switch following the initial setup, the SLAVE push button (ORT RHG) must be depressed to provide cueing to the new source. In the HMD/TADS mode, the TADS will unslave from the CPG IHADSS LOS when the ACQ SEL switch is changed to a new cueing source. When the SLAVE push button is depressed, the TADS will again slave to the CPG IHADSS LOS and cueing will be provided to the new ACQ SEL source. The PLT, however, merely selects CPG on his ACQ SEL switch to receive cueing.

NOTE 2: When cueing is selected, one cueing dot (azimuth or elevation) or two cueing dots (azimuth and elevation) will appear at the end of the LOS reticle segments. These cueing dots indicate the direction in which you must turn your head to be aligned with the referenced LOS. As the referenced LOS comes into the display FOV, the cued LOS reticle (dashed reticle) will appear on the HDU. This reticle represents the LOS of the se-lected source. As the HDU LOS comes within 4 degrees of the cued LOS reticle, the cueing dots will disappear.

TASK 1107

TASK: Perform aircraft position update function procedures.

CONDITIONS: In an AH-64 helicopter, an AH64CMS, or a CWEPT.

STANDARDS:

DESCRIPTION: To determine the aircraft present position and navigation system error relative to a known coordinate location, rotate the DEK mode select control to TGT. Use the ENTER or SPACE key to select the page containing the target location. Enter the UTM coordinates and altitude (MSL) of the update location. Place the TGT/NAV indexers to the number corresponding to the target address of the update location. Place the reticle of the selected sight (TADS or HMD) on the feature or object used as the update location. Enter the range from the aircraft to the update location using the laser range, autorange, or manual range. While tracking the feature or object at the update location, momentarily position the UPDT/ST switch (ORT LHG) outboard to UPDT. The aircraft present position and navigation system error are automatically calculated. These calculations are based on the update location coordinate data, selected sight pitch and yaw angles relative to the HARS horizon, and the range information. After updating the aircraft present position, display the position by selecting SP 1 on the DEK and entering the letter U. The updated present position is stored in the FCC for display only; it is not automatically sent to the doppler navigation system. Update the doppler navigation system if desired.

NOTE: This task should be accomplished at a hover for maximum accuracy. If the procedure is done while the aircraft is moving, it will be necessary to freeze the doppler present position display while simultaneously actuating the UPDT switch.

TASK 1140

TASK: Engage target with Hellfire.

CONDITIONS: In an AH-64 helicopter on an approved range, in an AH64CMS, or in a CWEPT with weapons initialization procedures (Task 1143) completed.

STANDARDS:

DESCRIPTION:

NOTE: The CPG may deselect the missile system by placing the WAS (ORT LHG) to the center position. The missile messages will disappear. However, the AND 4x4s will continue to provide missile status and inventory data as long as the MSL switch remains on.

NOTE: The PLT has ultimate missile system action authority. He can override missiles or rockets previously activated by the CPG.

NOTE 1: The missile system takes priority over the rocket system. Consequently, when one crew member has activated rockets and the other crew member activates missiles, the FCC will cease rocket operations and activate the missiles.

NOTE 2: The FCC gives PLT-activated missiles the highest weapons priority if the CPG becomes incapacitated.

STANDARDS:

DESCRIPTION:

NOTE 1: The message RKT-F-S will be displayed to the CPG in the HAD regardless of airspeed when the SIGHT SEL switch is in STBY.

NOTE 2: The LRF/D CCM switch allows use of the LRF/D system with integrity when laser backscatter or other obscurations are present. With the switch in the OFF position, the first laser return from the scene of interest determines the range the FCC uses to compute ballistic equations. With the switch in the CCM position, the FCC uses the last laser return. When a crew member observes unrealistic changes in the laser range being displayed (for example, range changes that cannot be reasonably attributed to aircraft or target movement), the CCM position should be selected.

NOTE: During a cooperative engagement, both crew members should monitor the aircraft position to provide adequate warning for obstacle avoidance.

WARNING

When the selected sight is off-axis and the cued LOS reticle is not visible, the display does not indicate that the gun is in the FXD mode. Consequently, the crew member who activates the gun must be aware that he has selected GUN-FXD to prevent accidental firings.

NOTE: Automatic range with HMD LOS is not recommended in the FXD mode because of the dynamics in the displayed range and the resultant dynamics in the cued LOS aiming reticle.
