Review: Weight and Balance Charts

1. If you weigh 200 lbs in the front seat, and your instructor weighs 120 lbs, are you in limits to fly this glider?

2. If you weigh 190 lbs in the front seat, and your instructor weighs 160 lbs, are you in limits to fly this glider?

3. If you weigh 110 lbs in the front seat, and your instructor weighs 100 lbs, are you in limits to fly this glider?

4. What is the maximum payload of this glider?

5. What is the empty weight of this glider?

6. If you weigh 130 lbs, can you fly this glider solo? What about if you weigh 95 lbs?

7. If you weigh 200 lbs, what is the maximum weight that your instructor can be?

8. If you weigh 90 lbs and your instructor weighs 130 lbs, are you in limits to fly this glider when the ballast is not installed? Why or why not?

pre take off checks bcistrsc

402.04 Launch Procedures, Checks and the Circuit

Pre-take off checks (BCISTRSC)

  • (B)allast. Weight limitations and ballast.
  • (C)ontrols. Controls functional; rudder pedals adjusted. (I)nstruments. Instruments checked; radio and altimeter set.
  • (S)poilers. Operation, then close and lock.
  • (T)rim. Trim set for takeoff. Trim shall be set full forward for aero tow and winch. Trim shall be set full aft for auto tow.
  • (R)elease. Operation and security.
  • (S)traps. Straps secure front and back seat.
  • (C)anopy/Door. Canopy, rear window and door closed and locked. Confirm security of canopy latch by touch.
hook up procedures and signals

402.04 Launch Procedures, Checks and the Circuit

Hook Up Procedures and Signals

Once the checks are done, and the pilot(s) are strapped in securely, the “ready for hook up” command can be given.

You will be shown how to do hook up in the first few days of the course.

launch signals wings level take up slack all out

402.04 Launch Procedures, Checks and the Circuit

Launch Signals, Wings Level,Take Up Slack, All Out

Before beginning the launch, the pilot looks for traffic everywhere in front of and above the glider. The pilot then asks the person standing at the wing, “All clear above and behind?” to learn if there is traffic that they cannot see. Then the launch signals can be given.

Launch Signals, Wings Level,Take Up Slack, All Out

“Level Wings” (thumb up) -in Comox, wait for radio clearance for take off before next step.

“Take up slack” (thumb up and index finger)

“All out” (thumb up and index and second fingers)

Tow plane gives full power.

stop signal

402.04 Launch Procedures, Checks and the Circuit

Stop Signal

The “STOP” signal can be given by anyone.

Raise both hands (if practical) above your head and yell “STOP” loudly and repeatedly.

pre release check

402.04 Launch Procedures, Checks and the Circuit

Pre-Release Check

  • shall be completed prior to releasing the glider from the tow aircraft:
  • (A)rea. Ensure glider is approaching the pre-briefed release point.
  • (A)ltitude. Ensure glider is at or is approaching the pre-briefed altitude.
  • (A)ttitude/Position. Ensure glider is in the proper attitude, i.e. wings level/high tow.
  • (T)raffic. Check for conflicting traffic in the practice area, especially at the release point.
  • (C)all. In Comox, you must add a “C” for “Call”, and make a pre-release radio call.
pre spin spiral stall check

402.04 Launch Procedures, Checks and the Circuit

Pre-spin/Spiral/Stall Check

  • shall be completed before executing either stall, spin or spiral dive exercises:
  • (A)ltitude. Ensure entry altitude will permit recovery by the required altitudes that follow.
  • (S)traps. Straps secure front and back.
  • (C)anopy. Canopy, rear window and door closed and locked. Confirm security of canopy latch by touch.
  • (O)bjects. Ensure no loose objects.
  • (T)raffic/Terrain. Check for conflicting traffic and ensure clear of built-up areas. Complete at least two 90 degree turns or one 180 degree turn, looking for traffic (especially below)
pre landing check swartsc

402.04 Launch Procedures, Checks and the Circuit

Pre-Landing Check (SWARTSC)

  • shall be completed prior to reaching a point abeam the touch-down point:
  • (S)poilers. Check operation and position.
  • (W)ind. Assess wind speed and direction.
  • (A)irspeed. Fly downwind at 50 mph Indicated Airspeed (IAS). Calculate the approach speed (50 mph plus wind speed, including any gust factor.)
  • (R)adio. Call Downwind/Base, as required.
  • (T)rim/Traffic. Set trim as required, and check for conflicting traffic.
  • (S)traps. Check front and back seat harness security.
  • (C)anopy. Canopy, rear window and door closed. Confirm security of canopy latch by touch.
acgp circuit including minima

402.04 Launch Procedures, Checks and the Circuit

ACGP Circuit Including Minima

The circuit is the way that we prepare to land.

-we plan to be at the initial point by 1000 feet Above Ground Level (AGL). That is 1100 feet indicated or Above Sea Level (ASL) in Comox.

-abeam at 800 AGL (900 ASL)

-turn base by 500 AGL (600 ASL)

-turn final by 300 AGL (400 ASL)

402.04 Launch Procedures, Checks and the Circuit

Review

  • 1. What are the steps of the Pre-Release Check?
        • Ballast, Controls, Instruments, Spoilers, Trim, Release, Straps, Canopy
  • 2. How do we signal “ready for hook up”?
  • fingers and thumbs of both hands make interlocking circles
  • 3. What are the launch signals?
  • wings level= thumb up
  • take up slack = thumb and index finger
  • all out = thumb, index and second fingers
  • 4. If you see something dangerous, what signal do you use?
  • stop signal = both hands in the air, yell “stop!”
  • 5. What signal does the glider give if it cannot release the tow rope?
  • moves to the left of the tow plane and rocks the wings

5. What does it mean if the tow plane waggles its rudder?

check that the spoilers are closed

6. What is the pre-release check?

Area, Altitude, Attitude, Traffic, Call (in Comox)

7. What is the downwind (pre-landing) check?

Spoilers, Wind, Airspeed, Radio, Trim/Traffic, Straps, Canopy

8. What are the minimum circuit altitudes in Comox?

IP: 1100 ASL, abeam: 900 ASL, base turn: 600 ASL, final turn: 400 ASL
