HAAR Flashcards
3-3-4-2
Fuel Transfer Rates
500-1000 lbs per minute
3-3-4-2
HAAR Airspeed
110-115 KIAS
3-3-4-2
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.
3-3-4-2
Minimum Distance from ARIP to ARCP
6 NM
3-3-4-2
ARCP Definition
Normally the earliest point the tanker can pass abeam the receiver.
3-3-4-2
Four Stages of HAAR
1- Rendezvous (intercept/escort)
2- Join-up
3- Contact/Fuel Transfer
4- Post AAR

Visibility
Visual and Electronic
Visual=3 NM
Electronic=1 NM
3-3-4-2
Minimum Ceilings/Cloud Clearance
1000 ft of vertical clearance from the top or bottom of a broken/overcast ceiling during HAAR.
3-3-4-2
RV Procedures Definition
Provides tanker means of transitioning from escort/intercept conditions to a position 1/2 NM in trail of receiver ready to begin join-up.
3-3-4-2
Communications
When will receivers and tankers monitor primary and alternate AAR frequencies?
Minimum or 10 minutes prior to ARCT.
3-3-4-2
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
Join-Up Procedures Definition
Enable the tanker to proceed from 1/2 NM in trail to the lead position.
3-3-4-2
When can receiver maneuver to observation position?
Once the tanker has accepted the lead.
3-3-4-2
Crossover Parameters
100ft aft (behind tankers vertical stabilizer)
50ft up (above tankers vertical stabilizer)
3-3-4-2
WARNING
When can the tanker initiate a turn?
Only when receiver is established in either
1- Refueling
2- Echelon (observation)
3-3-4-2
CAUTION
If drogue is rotating > 1 revolution per second what can it damage?
Probe nozzle lock ring.
