WARNING with HAAR Airspeeds (2)

Airspeeds less than 105 KIAS may cause drogue to become slightly unstable.
Also the tanker has a small margin for safety above power-off stall speed.

Arrival at ARCP Timing

Both receivers and tankers should plan to arrive at ARCP on time, however:
-Receivers can be up to 1 minute early
-Tankers can be up to 1 minute late

3-3-4-2 Echo Rendezvous Definition

The only RV where the receiver maneuvers to affect the RV and join-up.

3-3-4-2 Golf Rendezvous Definition

Tanker approaches receiver from the rear.

3-3-4-2 Hotel Rendezvous Requirement

VMC

3-3-4-2 HAAR Formation Option 1 # of Tankers # of Receivers

2 Tankers (one primary and one spare) Up to 4 receivers

3-3-4-2 HAAR Formation Option 2 (Trail) # of Tankers # of Receivers

At least 2 primary tankers and 1 spare tanker (if available). More than 4 receivers.

3-3-4-2 If transitioning to spare tanker, what are the primary’s actions?

1- Accelerate 2- Climb 500 ft 3- Rejoin the flight in the spare position at the end of the formation

3-3-4-2 Lost Contact Procedures Non-Mountainous

Primary: Maintain heading, accelerate to cruise airspeed, climb to MSA Spare Turn right 45 degrees, accelerate to cruise airspeed, climb to MSA + 1000ft Receivers Turn left (20, 40, 60) Climb to MSA+ (300, 600, 900)

3-3-4-2 Lost Contact Procedures Timing Start

Once an aircraft reaches its assigned altitude.

3-3-4-2 Mountainous Terrain Definition

500ft change in surface altitude over 1/2 NM.

3-3-4-2 EMCON 1 Definition

Any and all emitters.

3-3-4-2 EMCON 2 Definition

Restricted R/T Communications.

3-3-4-2 Which EMCON is the desired standard? for day to day HAAR?

EMCON 2

3-3-4-2 EMCON 3 Definition

Silent R/T Use of other emitters is authorized.

3-3-4-2 EMCON 4 Definition

Emission Out. No emitters will be used unless specifically authorized.

3-3-4-2 Light Signals One Green Light

Cleared to contact and/or crossover.

3-3-4-2 Light Signals One White Light

Proceed to observation position.

3-3-4-2 Light Signals Two White Lights

Tanker directed crossover.

3-3-4-2 Light Signals One Amber Light

Prepare to turn.

3-3-4-2 Light Signals Two Amber Lights

Unable to pass fuel, go to spare.

3-3-4-2 Light Signals Multiple Red Lights

Breakaway

3-3-4-2 Light Signals Receiver to Tanker Reset Reel Response

1- Disconnect 2- Move outboard of the hose 3- Emit one steady light

3-3-4-2 Light Signals Receiver Preparing to Disconnect

Flashes position/formation light for 5 sec.

AFMAN11-2HH-60WV3 HAAR Minimum Altitude for Training

1000ft AGL/AWL

AFTTP 3-3 Join-Up Altitudes and Airspeeds Established No Later Than

ARIP

AFTTP 3-3 Astern Position Definition

1- 5 to 10ft aft of the drogue 2- Probe aligned for a run-in 3- Aircraft in trim

AFTTP 3-3 Fuel Flow Termination Primary Method

Tanker's automatic fuel shutoff.

AFTTP 3-3 WARNING Associated with Simultaneous Refueling

2 receivers will not disconnect or maneuver for contact simultaneously.

AFTTP 3-3 Toboggan Technique

Establish a rate of descent between 300 to 500 fpm.

3-3-4-2 Hard Hose (Dead Hose) Definition

Hose slack is not properly taken up on contact. Any resulting hose whip is likely to damage the receiver’s probe.

3-3-4-2 Conditions that require a breakaway include, but are not limited to:

1- Excessive receiver closure rates 2- Receiver or tanker engine failure 3- Excessive fuel leak

3-3-4-2 Receiver to Tanker Light Signals Emergency Fuel Requirement Exists

1- Extended Probe 2- Visible landing or search light ON 3- IFF on Emergency

3-3-4-2 WARNING When can rotary wing receiver crews attempt probe-to-drogue contact in a turn at night?

If an emergency fuel condition exists.

3-3-4-2 CAUTION Which rotation direction of the drogue may unthread the probe nozzle?

Clockwise

3-3-4-2 Tanker No Shows Receiver Actions

Continue along the refueling track at the join-up altitude until reaching the abort point or turn point (static track).

3-3-4-2 Delta Rendezvous Electronic and Visual Procedure Options

Visual: Tanker may initiate their turn when the receiver is at the 10 o’clock. Electronic: 3 minutes prior to ARCT, tanker will start their turn.

3-3-4-2 Echo Rendezvous Standard and Alternate Tanker Orbits

Standard: Tanker maintains orbit consisting of 6 NM legs with 1/2 standard rate turns. Results in 10 minutes for one complete orbit. Alternate: Tanker orbits around a pre-briefed fixed point while maintaining a constant bank turn (usually 20 degree).

3-3-4-2 Echo Rendezvous Receivers Vertical Separation

Maintain 500ft vertical separation until tanker is in sight.

3-3-4-2 Lost Contact Procedures Non-Mountaineous How long do you maintain adjusted heading?

30 seconds
