MH60T Trivia #426-450
This trivia series distills over 20 years of flight manual study into 500+ focused questions and answers, posted in 25 question sets. It’s not a substitute for the manual, but rather an aid to facilitate study and strengthen airmanship. During your review, ask yourself: How is this operationally relevant? Do I need to memorize it, or just be familiar with it? Should I review more on this topic?
- Q: Max weight for the sling?
A: 600 lbs.
- Q: When will the weak link part?
A: With more than 300 lbs. of force.
- Q: Length of usable hoist cable?
A: 200′.
- Q: Rate of cable movement using pendant or hand grip?
A: 0-250 fpm, slows to 50 fpm last 10′ up, 5′ down.
- Q: Rate of cable movement using cyclic stick grip switches?
A: Cyclic: 100 fpm, overides pendant control.
- Q: Rate of cable movement using back up control?
A: Back up control: 85 fpm (will not slow the last 10′ up or 5′ down).
- Q: Hoist control priority?
A: Lowest to highest priority – pendant, fixed grip, cyclic, back up control.
- Q: What does the hoist switch do (on the overhead console)?
A: Activates the hoist fan (ALL or COCKPIT), allows the fixed grip, pendant and cyclic controls to work (ALL or COCKPIT) and designates shear authority (COCKPIT cyclic can shear only, ALL crew and cyclics can shear). *For clarification, the fixed grip and pendant will work when the switch is in the COCKPIT position. However, the flight mechanic will not be able to shear from the hoist control panel.
- Q: Does back up control work regardless of the position of the hoist switch?
A: Yes. The switch can be in ALL, COCKPIT or OFF. Back up control will work as long as the back up pump is on.
- Q: Hoist back up control caution?
A: When operating in back up control the full up limit switch is inactive making it possible to jam the hook into the cable wire housing.
- Q: Max altitude for DMB deployment?
A: 500′ AWL, 12′ water depth.
- Q: Range of altitude/airspeed for SLDMB v.3 deployment?
A: 100-10,000’ and 45-120 KIAS
- Q: SLDMB v. 3 warning?
A: The mast is spring-loaded and will extend 16.5 inches, if released may cause personal injury (abbreviated).
- Q: SLDMB v. 3 note and caution?
A: Minimum water depth is 10’ to avoid SLDMB contact with the bottom. The SLDMB should exit the aircraft non chute side first (to avoid tumbling and tangling in the chute – abbreviated).
- Q: Max altitude for indirect pump deployment?
A: Below 25′.
- Q: Procedures for indirect pump deployment?
A: The weight bag is connected to the weak link. Standard trail line delivery. After the trail line is payed out, the non-weak link end is connected to the D- rings on the bridle then FM reports “READY TO DEPLOY THE PUMP.” The pilot descends to a low hover then directs the FM to “DEPLOY THE PUMP.” Once the PF reports “CEASE COMMANDS” the FM shall report “HOIST COMPLETE.”
- Q: Max altitude for a mass rescue raft deployment?
A: Below 25′.
- Q: Procedures for mass rescue raft deployment?
A: FM pays out 3′ of trail line at each end of the trail line. The weak link is attached to the inflation cable of the raft. A weight bag is connected to the other end. After “RESCUE CHECKLIST PART II COMPLETE…”, the pilot calls “CONN ME IN.” FM conns helo upwind of survivors to an altitude less than 25′. Pilot commands “DEPLOY THE RAFT.” FM clears the helo to move back and left. When the line becomes taught, the FM pulls sharply, inflating the raft, then discards the line.
- Q: Requirements for a free fall?
A: Day, below 15′ AWL, min. water depth of 12′.
- Q: Check swimmer altitude, free fall?
A: Less than 30′.
- Q: During a free fall or harness deployment, the FM will position the helicopter so that the survivor is just outside the rotor wash but no less than ______ from the helicopter?
A: 5-10′.
- Q: Free fall and harness deployment in calm seas, the survivor will be at the_______ position?
A: 2-3 o’clock position.
- Q: When delivering the litter to the swimmer in the water, the litter shall be placed _______ from the swimmer?
A: 5-10′.
- Q: When is a trail line used to deliver the litter to the water?
A: The trail line shall not be used to deliver any device to a rescue swimmer in the water.
- Q: During a direct deployment, the FM will position the helicopter so that the swimmer can be deployed within _________ of the survivor?
A: 2-3′.
