What is the effect of rain on the flying characteristics of the 2-33A? Water build-up on the upper surfaces of the wing can raise stall speeds by 1-2 mph. Water around the static ports of the pitot-static boom can affect position error and raise the indicated airspeed at which stall occurs by an additional 1-2 mph.
Glider launches shall not commence or continue during periods of precipitation that are in excess of “light”. “Light Precipitation” is defined as: a. Individual rain drops are easily seen; b. Hardly any spray over hard surfaces; and c. Puddles form very slowly.
What is the minimum allowable distance for hazardous weather before operations must cease? In no case shall ACGP air operations commence or continue if weather hazardous to gliding operations is within 5 miles.
What is the maximum allowable gust differential? The maximum permissible gust differential is 10 knots or 12 mph.
When does a gust condition exist? Firstly, the main gust peak is 15 knots or greater and secondly the peak gust speed is at least 5 knots higher than the two minute average speed. Additionally, gust conditions normally include rapid and repeated changes in wind direction.
When must an LCO be on duty? An LCO shall be on duty when conducting ACGP glider familiarization and/or glider training operations that involve multiple launches.
Which parts of the glider shall be reviewed on a Limited Pre-Flight Inspection (Walk Around) immediately before a flight? a. Wing leading edges; b. Wheels and skid; c. Elevator pushrod assembly (including bolts); and d. Pitot/static assembly.
What is the minimum recovery altitude for stalls? Stalls shall be recovered above 1500 feet AGL.
What is the minimum recovery altitude for spins? Incipient and full spins shall be recovered above 2000 feet AGL
What is the minimum recovery altitude for spriral dives? Spirals shall be recovered above 1500 feet AGL
What is the minimum altitude for forward slipping? Forward slips shall not be continued below 150 feet AGL, except in an emergency
What is the minimum altitude for completing turning final? 300 feet (plan to be established on final by 300' AGL)
What is the minimum altitude for completing turning base? 500 feet (plan to be established on base by 500' AGL)
What is the minimum length for a vehicle tow rope for ground movements? The minimum length of rope between a tow vehicle and glider shall be 30 feet.
What is the maximum number of gliders that can be towed by one vehicle, with ropes joining each one to the one in front? To prevent structural damage to the lead glider, a maximum of six gliders are to be towed at once and this number is to be reduced when rough terrain or winds dictate.
What is the minimum length of an ACGP air tow rope? The minimum length of an ACGP air tow rope shall be 200 feet.
Why has a minimum length for the air tow rope been established? The risk of tow aircraft upset increases as rope length is decreased
If personnel or objects are in front of the nose of a glider about to take off, where must they stand? All personnel and support equipment positioned forward of the nose of that aircraft must be at least 50 feet away from its nearest wingtip. This does not apply to runway and taxiway markers, or fire extinguishers.
What is the normal air tow speed for the 2-33A? Normal air tow speeds shall be 65 to 70 mph. During transits, airspeeds may be increased to 90 mph IAS for the 2-33. If turbulence is encountered during transits, airspeed should be immediately reduced.
What are the three ways that slack can be (accidentally) created while on air tow? a. Climbing, followed by the sudden descent, causes excess speed & results in a slack tow rope b. Over-banking in a turn & moves rapidly to the inside, it will accelerate relative to the tow plane c. In a descent the glider may catch up to the tow plane
What are four hazards of slack rope on air tow? The hazards of a slack tow rope include entanglement, an inadvertent back release, a rope break, or damage to the canopy from a released tow rope and ring.
What steps should you take if the canopy inadvertently opens in flight? a. safely fly the aircraft b. Assess, considering the phase of flight, position and altitude; c. If able, close the canopy. If unable, plan for sufficient altitude and airspeed to compensate for the increased drag when returning for landing
How might the tow pilot visually signal that the spoilers are open on the glider? The tow pilot (time permitting) will vigorously move the rudder from side to side
What steps should you follow in the case of a premature release while on tow? (G)lide - Set or maintain normal gliding attitude; (A)ssess - Altitude and location; (S)elect - Appropriate response and landing area; and (P)ull - Release twice.
If you have a launch failure (premature release) at 100 feet AGL or below, what are your options? a. The glider pilot should attempt to land straight ahead making minor deviations to avoid obstacles. b. If the tow aircraft lands straight ahead, the glider shall be manoeuvred to its right
If you have a launch failure (premature release) between 100 feet AGL and 200 feet AGL, what are your options? a. Attempt to land straight ahead making minor deviations to avoid obstacles b. If the tow plane lands straight ahead, the glider shall move right c. turns up to 90 deg may be made above 100' AGL. Altitude & runway remaining are critical factors
If you have a launch failure (premature release) between 200 feet AGL and 500 feet AGL, what are your options? Select the best option from the following: a. Straight ahead landing; b. Downwind landing; or c. Crosswind or alternate runway landing.
If you have a launch failure (premature release) above 500 feet AGL, what are your options? Select the best option from the following: a. Modified circuit b. Crosswind or alternate runway c. Downwind landing d. Straight ahead landing
