OverviewOverview
• Site location is critical.
• Need NLT 2,000’ Alt. Launch. (4,000’ Rwy)
• If less, can’t meet O flight objectives

• Winch launches--when things go wrong, they can go wrong in a hurry
• Communication and procedure is critical to Safety.
• Modified role of Supervisor of Flight and implementation of a scripted launch procedure.

• Installed Equipment-Winch:
• Air-band radio; PTT switches, headphones each seat.

• SOF role differs in Winch Launches SOF role differs in Winch Launches vs. Aero Tow in critical waysvs. Aero Tow in critical ways
• Similar to Aero Tow:Similar to Aero Tow:
• Assures conditions on ground and in the air are conducive to safe launch
• No launch commences except under No launch commences except under supervisory control of the SOFsupervisory control of the SOF
Key Role of the Supervisor of Flight Key Role of the Supervisor of Flight (SOF) in Winch Launches(SOF) in Winch Launches
Role of SoF, ContinuedRole of SoF, Continued
• Different from Aero Tow:
•SoF is the conductor of a strictly structured, scripted launch procedure
• Script is practiced by key participants at the start of the launch day
• Script cards are in Glider & Winch
• Process is critical to Launch Safety
SOF: “CAP Winch Ops Prepare To Launch”
Glider: “Winch, 8BA comm check”
Winch: “8BA, loud & clear, how me?”
Glider: “Loud & clear”
Glider: “Dual launch, target speed 55-60 KTS”
Winch: “Dual launch, target 55-60 knots”
Glider: Area clear to launch
SOF: Area clear to launch
1. Establish Communication
Scripted Launch ProcedureScripted Launch Procedure
--SOF sees glider wings level
SOF: “Winch, You are cleared for launch”
Winch: “Cleared for launch”
Glider: “Glider ready”
Winch: “Winch ready”
Glider: “Take-up slack”
Winch: “Taking up slack”
Glider: “Go—Go—Go”
--Winch applies take-off power
2. Launch Sequence
Scripted Launch ProcedureScripted Launch Procedure
Glider: (after rotation) “50”
Glider: (mid profile) “58”
Glider: (approaching round off) “60”
Winch: (top of arc) “Powering Back”
(release)
3. In-Flight Communications

Emergency Calls:

• Training: How to accomplish• Winch Drivers• Glider Pilots
• Winch Mobility must be matched with available crew at each site utilized.
• If multiple sites are used, how will CG gliders be relocated between sites.• Aero Tow• Disassembled, Packed, Trailered,
Unpacked, Assembled• Just because the winch is mobile does not
mean the program is
Program Manager ConsiderationsProgram Manager Considerations
Site Selection
• New and different technology spooks traditional airport operators & users
• Cross rwy locations are likely out
• Using 10 gal of diesel fuel per day, winch does not return income to the field
• Friend raising is important
Program Manager ConsiderationsProgram Manager Considerations
Site Selection
• Maximize rwy length
• Height dependant on length
• Winch location can exceed rwy length if area is clear, supports retrieval vehicle and has good lines of sight
• Turf is fine for launch,
• But limited use after rains, esp. if line retrieval vehicle is heavy.
Program Mgr. ConsiderationsProgram Mgr. ConsiderationsSite Selection
Long single rwy - Low traffic environment.
Winch and glider package. With no Tow Plane available.
• Forces team to maximize capabilities of the winch, not rely on aero for high tows.
• Focuses training on winch operations; pilots and winch drivers.
