Figure 6-5. Suggested format of a crew briefing checklist

STANDARDS:

DESCRIPTION: In performing this task, the PC must brief the mandatory items from DA Form 5484-R and the crew briefing checklist. The PC will use a checklist similar to the one shown in Figure 6-5 to conduct the aircrew briefing. He also must ensure that the aircrew collectively visualizes and rehearses expected and potential unexpected events from takeoff to tie-down. The PC should include in the rehearsal all factors of the flight; these include the actions, duties, and responsibilities of each crew member. The crew members will discuss and acknowledge a common understanding of critical map features, flight segments and events, tactical options, emergency procedures, and operational risks associated with the planned mission. The PC will then identify mission and flight requirements that will demand effective communication and proper sequencing and timing of actions by the crew. The PC must realize that added caution may be necessary if the crew members have not flown together as a battle-rostered crew. The other crew member(s) will acknowledge that they understand assigned actions, duties, and responsibilities. The overall goal is to reduce uncertainty by preplanning a margin of error to compensate for unexpected events.

TASK 1004

TASK: Prepare DA Form 5701-R (UH-60/AH-64 Performance Planning Card).

CONDITIONS: Given a completed DD Form 365-4 (Weight and Balance Clearance Form F-Tactical); TM 55-1520-238-10; environmental conditions at takeoff, en route, and at destination; and a blank DA Form 5701-R.

NOTE: A blank copy of DA Form 5701-R is at the back of this training circular. Reproduce it locally on 5 1/2- by 8-inch paper or card stock.

STANDARDS:

DESCRIPTION:

Step 1: Enter the torque factor chart on the left of the appropriate temperature. Move right to the ETF or ATF.

Step 2: Move vertically to the bottom of the chart, and note the torque ratio.

NOTE 1: This chart allows the pilot to determine engine performance when an aircraft is operating below +35 degrees Celsius with a less than specification (1.0) engine. For engines operating at temperatures above +35 degrees Celsius, the torque ratio equals the ETF or ATF and performance is not improved. Operating at temperatures of -15 degrees Celsius and below, all engines perform as specification engines because of the increased efficiency from the denser air.

NOTE 2: Each vertical line on the torque ration chart has a value of .002.

Step 1: Using the maximum torque available (30-minute limit) chart, enter the graph at the appropriate FAT.

Step 2: Move horizontally to PA. Then move vertically to the specification torque available.

NOTE 1: If the ATF is 1.0, enter the torque derived from step 2 above (not to exceed continuous torque limit, dual-engine) in the maximum torque available (dual-engine) block(s).

NOTE 2: If the ATF is less than 1.0, use the torque conversion chart (see Step 3 below) or multiply the specification torque by the torque ratio to determine actual torque available.

Step 3: Enter the torque conversion chart at the bottom at the specification torque available per engine %; read up until intersecting the TR (not to exceed continuous torque limit, dual-engine), and then left to the actual torque available. Record in the maximum torque available (dual engine) block(s).

NOTE: If the ETF is different for each engine, compute maximum torque available (single-engine) for each engine using the torque ratio derived from the respective engine's ETF. Do not use the ATF.

NOTE: If the ETF is different for each engine, compute the maximum continuous torque available (single-engine) for each engine using the torque ratio derived from the respective engine's ETF. Do not use the ATF.

Step 1: OGE. Using the hover ceiling maximum torque available (30-minute limit) chart, enter at PA. Move horizontally to FAT, and move vertically to read OGE gross weight.

Step 2: IGE. Using the hover ceiling maximum torque available (30-minute limit) chart, enter at PA. Move horizontally to FAT, and move vertically to read the 5-foot wheel height. Then move horizontally to read maximum gross weight IGE.

Step 1. Using the hover chart, enter at the known pressure altitude. Move right to the temperature, then draw a line down to the bottom of the lower grid.

Step 2. Enter the top left grid at maximum torque available. Move down to the desired wheel height (OGE OR IGE), and then move right to intersect the previously drawn line. Read the gross weight. This is the maximum gross weight at which the helicopter will hover.

NOTE: The use of a 10-foot power check and associated TM 1-1520-238-CL charts may be appropriate if current conditions have changed significantly.

NOTE: A change in GWT of about 200 pounds equates to a change in torque of l percent.

NOTE: If the ETF is different for each engine, compute single engine capability TAS (min/max) using maximum torque available (single-engine) derived from the lesser of the two ETFs. Do not use the ATF.

NOTE: If the ETF is different for each engine, compute the maximum allowable gross weight (single-engine) per (9) above using maximum torque available (single-engine) derived from the lesser of the two ETFs. Do not use the ATF.

NOTE 1: A change in aircraft configuration or flat plate drag, as well as use of the anti-icing system, will affect performance computations.

NOTE 2: Crew members may use approved computer programs to derive the required information during flights other than for readiness level progression and evaluation.

NOTE 3: Record "avoid" and "caution" altitudes from TM 1-1520-238-10, Chapter 9, in the Remarks section.

NOTE 4: Crew members should be aware of minimum single-engine speeds for all departure, arrival, and low-speed/low-altitude conditions.

TASK 1015

TASK: Perform ground taxi.

CONDITIONS: In an AH-64 helicopter or an AH64CMS, on a suitable surface, with the before-taxi check completed and the aircraft cleared.

STANDARDS:

DESCRIPTION:

NOTE 1: During taxi with the tail wheel unlocked, fuselage roll attitude is controlled with the cyclic. The turn and slip indicator, the standby attitude indicator, the remote attitude indicator, and symbology, as well as outside visual cues, may be used to reference fuselage roll attitude. The accepted method for ground taxi is with the tail wheel in the unlocked position.

NOTE 2: Emergency stops may be performed by applying the wheel brakes, by using aerodynamic braking, or by bringing the aircraft to a hover, depending on ground velocity.

NOTE 3: In BUCS-equipped aircraft, the P should avoid applying excessive pressure when blocking the brakes. Excessive brake pressure may shear a SPAD.

NOTE 4: During rearward taxi, the trailing arm tail wheel may swivel 180 degrees, causing momentary heading instability.

NOTE 5: Excessive cyclic input and insufficient collective application may result in droop-stop pounding.

TASK 1017

TASK: Perform hovering flight.

CONDITIONS: In an AH-64 helicopter or an AH64CMS with the before-takeoff check completed and the aircraft cleared.

STANDARDS:

DESCRIPTION:

NIGHT OR NVD CONSIDERATIONS: Movement over areas of limited contrast, such as tall grass, water, or desert, tends to cause spatial disorientation. To avoid spatial disorientation, seek hover areas that provide adequate contrast and use proper scanning techniques. If disorientation occurs, apply sufficient power and execute a takeoff. If a takeoff is not feasible, try to maneuver the aircraft forward and down to the ground to limit the possibility of touchdown with sideward or rearward movement.

NVS TECHNIQUES:

NOTE 1: The location and gimbal limits of the FLIR sensor prevent the P* from seeing the actual touchdown point during this maneuver. He must obtain clearance of the intended touchdown point before positioning the aircraft over the point. If uneven surface conditions are suspected, the crew should set the parking brakes before initiating the descent.

NOTE 2: Under normal loading conditions, the aircraft will hover approximately 3 degrees left side low.

NOTE 3: Use of the manual stabilator mode reduces airframe vibration in strong crosswinds or tail winds.

TASK 1018

TASK: Perform a normal takeoff.

CONDITIONS: In an AH-64 helicopter or an AH64CMS with the hover power and before-takeoff checks completed and the aircraft cleared.

STANDARDS:

DESCRIPTION:

NOTE 1: The P* must avoid nose-low accelerative attitudes in excess of 10 degrees.

NOTE 2: The height velocity diagram in TM 55-1520-238-10, Chapter 5, displays "avoid areas." This diagram assumes the availability of a suitable forced landing area in case of engine failure. If a suitable forced landing area is not available, the P* should accelerate the aircraft to minimum single-engine airspeed prior to establishing the desired climb rate.

NOTE 3: Stabilator mode selection will affect the amount of cyclic required to achieve the climb pitch attitude and the power required to accelerate and climb in the desired attitude (drag related). Under normal circumstances, the automatic stabilator program provides an optimum schedule for acceleration. However, the P* can use the manual mode stabilator control to fine-tune drag versus airspeed and achieve lower power requirements for a given airspeed. The P* will announce the use of the manual stabilator before the master caution light illuminates.

NIGHT OR NVD CONSIDERATIONS:

NOTE: Visual obstacles, such as shadows, should be treated the same as physical obstacles.

TASK 1019

TASK: Perform a rolling takeoff (minimum power takeoff).

CONDITIONS: In an AH-64 helicopter or an AH64CMS with the hover power and before-takeoff checks completed and the aircraft cleared.

STANDARDS:

DESCRIPTION:

NOTE 1: This maneuver simulates operations at or near maximum allowable gross weight and at density altitudes and temperatures where maximum power available is not sufficient for a normal takeoff. It also simulates operations in environments where sand, dust, and snow are present.

NOTE 2: The P* must not allow the aircraft nose to drop below the fuselage level until the aircraft departs the takeoff surface.

TASK 1020

TASK: Perform simulated maximum performance takeoff.

CONDITIONS: In an AH-64 helicopter or an AH64CMS with the hover power and before-takeoff checks completed and the aircraft cleared.

STANDARDS:

DESCRIPTION:

NOTE 1: This is a training maneuver only. It simulates aircraft operations at or near maximum allowable gross weight or at a density altitude where maximum power available represents just enough power to take off and clear obstacles. This maneuver should not be confused with a confined area or terrain flight takeoff.

NOTE 2: Hover OGE power is required for simulated maximum performance takeoffs.

STANDARDS:

DESCRIPTION:

NOTE: During training, the recommended airspeed is 80 KIAS on crosswind and base legs and 100 KIAS on the downwind leg.

*NIGHT OR NVD CONSIDERATIONS: For an NVD traffic pattern, the P* should maintain a continuous coordinated turn to the downwind leg and establish airspeed and altitude as directed. He should initiate the turn from downwind when in a position to make a continuous turn to the final approach course.

CONDITIONS: In an AH-64 helicopter or an AH64CMS with the before-landing check completed.

STANDARDS:

DESCRIPTION:

NOTE 1: During training, the recommended entry airspeed is 80 KIAS.

NOTE 2: Steep approaches can place the aircraft in potential settling-with-power conditions. The crew must be familiar with diagnosing and correcting these situations.

NOTE 3: The crew should make the decision to go around if visual contact with the touchdown point is lost or if it becomes apparent that it will be lost. They must make the decision to go around before descending below obstacles or decelerating below ETL.

NOTE 4: FM 1-202 contains procedures for reducing the hazards associated with the loss of visual references during the landing because of blowing sand or snow.

TASK 1029

TASK: Perform roll-on landing.

CONDITIONS: In an AH-64 helicopter or an AH64CMS with a suitable landing area selected and the before-landing check completed.

STANDARDS:

DESCRIPTION:

NOTE 1: The P* will announce "Braking" when he intends to apply brake pressure. The P will acknowledge by announcing "Blocking."

NOTE 2: In BUCS-equipped aircraft, the P will avoid applying excessive pressure when blocking the brakes. Excessive brake pressure may shear a SPAD.

NOTE 3: During training, the crew will use 10 percent below hover torque as a simulated power limit.

NIGHT OR NVD CONSIDERATIONS: Altitude, apparent ground speed, and rate of closure are difficult to estimate at night. Therefore, the rate of descent at night during the final 100 feet should be slightly slower than during the day to avoid abrupt attitude changes at low altitudes.

NVS TECHNIQUES:

NOTE: This maneuver should be performed in an environment where obscurants such as sand, dust, or snow are present.

TASK 1032

TASK: Perform slope operations.

CONDITIONS: In an AH-64 helicopter or an AH64CMS with the aircraft cleared.

STANDARDS:

DESCRIPTION:

NOTE 1: Before conducting slope operations, the crew must understand dynamic rollover characteristics.

NOTE 2: The crew will confirm that the parking brakes are set. If the brakes must be set in flight, the CPG should be on the controls and will announce "Blocking." The PLT will acknowledge by announcing "Braking" and will set the parking brakes.

NOTE 3: In BUCS-equipped aircraft, the P should avoid applying excessive pressure when blocking or setting the brakes. Excessive brake pressure may shear a SPAD.

NOTE 4: When the tail wheel is locked and on the ground, overcontrolling the pedals results in roll oscillations, which are caused by the tail rotor torque effect.

NOTE 5: The P* should be aware of the common tendency to become tense and, as a result, to overcontrol the aircraft while performing slope operations.

NIGHT OR NVD CONSIDERATIONS: When conducting slope operations, the crew should select reference points to determine slope angles. (References will probably be limited and difficult to ascertain.) If, at any time, successful completion of the landing is doubtful, the crew must abort the maneuver.

TASK 1054

TASK: Perform simulated single-engine failure, OGE hover.

CONDITIONS: In an AH-64 helicopter with an IP, an AH64CMS, or a CWEPT with the before-landing check completed.

STANDARDS:

DESCRIPTION:

NOTE 1: When this task is conducted in the aircraft at or above 400 feet AGL, the IP may retard one power lever to IDLE. How-ever, when this task is performed in the aircraft below 400 feet AGL, both power levers must remain in the FLY position. The IP will announce input to or when assuming the aircraft controls.

NOTE 2: Hover OGE power is required for simulated single-engine failure, OGE hover.

TASK 1055

TASK: Perform single-engine landing.

CONDITIONS: In an AH-64 helicopter with an IP, an AH64CMS, or a CWEPT, with the before-landing check completed, and given entry altitude and airspeed.

STANDARDS:

DESCRIPTION:

NOTE 1: The P* will announce "Braking" when he intends to apply brake pressure. The P will acknowledge by announcing "Blocking."

NOTE 2: In BUCS-equipped aircraft, the P should avoid applying excessive pressure when blocking the brakes. Excessive brake pressure may shear a SPAD.

NOTE 3: Prior to performing the maneuver, the IP must ensure that the aircraft can be operated within single-engine limitations. The IP will announce input to or when assuming the aircraft controls.

NOTE 4: This task may be performed as a continuation of Task 1053.

TASK 1062

TASK: Perform ECU lockout operations.

CONDITIONS: In an AH-64 helicopter with an IP, an AH64CMS, or a CWEPT and given an emergency condition that requires operation in ECU lockout.

STANDARDS:

DESCRIPTION:

NOTE: When the power lever on one engine is retarded to IDLE, the torque on the other engine will double. The P* must monitor the opposite engine torque and Np to ensure that they remain within engine limitations. The IP will announce any input to or when assuming the aircraft controls.

TASK 1064

TASK: Perform terrain flight navigation.

CONDITIONS: In an AH-64 helicopter or an AH64CMS and given a mission briefing and the required maps and materials.

STANDARDS:

DESCRIPTION:

NOTE 1: If the area permits, the crew should navigate at least 20 kilometers during NOE flight training or 40 kilometers during low-level or contour flight training.

NOTE 2: Each of the methods for stating heading information is appropriate under specific conditions. When a number of terrain features are visible and prominent enough for the P* to recognize them, the most appropriate method is navigation instruction toward the terrain feature in view. Navigation instructions toward a distant, unseen terrain feature is appropriate when few changes are anticipated. When forward visibility is restricted and frequent changes are necessary, controlled turning instructions are more appropriate. As a general rule, clock headings by themselves should be avoided. However, clock headings are recommended when associated with a terrain feature and with controlled turning instructions.

TASK 1068

TASK: Perform or describe emergency procedures.

CONDITIONS: In an AH-64 helicopter with an IP or an IE, in an AH64CMS, in a CWEPT, or orally in a classroom environment and given a specific emergency condition.

STANDARDS:

DESCRIPTION:

NOTE 1: Crews will perform emergency procedures that are prohibited from practice in the aircraft in the AH64CMS or in a CWEPT, or they will discuss them orally.

NOTE 2: The preferred method of accomplishing emergency procedures is for the P* to fly the aircraft and the P to perform the emergency procedure steps.
