Airframe 2

What is the effect of too tight or over-tensioned control cables?. Slack in controls. Heaviness and hard movement. Faster control response.

What is the effect of broken control cable pulleys?. Smooth movement. Worn pulleys and hard movement. Reduced lift.

How to fix spongy brakes?. Replace brake pads. Bleed the brakes. Increase fluid pressure.

What is the purpose of torque links on oleo struts?. Increase landing gear travel. Maintain correct wheel alignment. Reduce hydraulic pressure.

35. What does the nose gear centering cam do?. Helps steering on ground. Centers nosewheel before entering wheel well. Locks nosegear in place.

36. What happens if landing gear fails to retract fully?. Insufficient hydraulic fluid. Engine failure. Tire overinflation.

What absorbs most impact upon landing?. Tires. Wing structure. Oil being forced through metered opening in struts.

Effect of broken piston return spring in master cylinder?. Brakes drag. Brakes lock. Fluid leaks.

Effect of restricted compensator port?. Faster brake release. Slow brake release. No effect.

Purpose of de-booster?. Increase brake pressure. Reduce pressure to brakes. Lock brakes.

How long after flight before checking tire pressure?. Immediately. At least 2 hours (3 hours in hot weather). 30 minutes.

What happens if a tire melts its fusible plug?. Tire must be scrapped. Reinflate tire. Replace valve.

Which component allows flow in one direction only?. Relief valve. Check valve. Selector valve.

Which valve has the highest pressure setting?. Check valve. Thermal relief valve. Flow control valve.

Purpose of surge chamber?. Increase flow. Absorb pressure shock. Reduce temperature.

Purpose of booster in control system?. Aid pilot in moving controls. Lock controls in place. Reduce hydraulic fluid.

Chattering of hydraulic pump during run-up indicates?. Low fluid. Air in the system. Pump failure.

Purpose of pressure accumulator?. Maintain system pressure. Increase pump speed. Cool hydraulic fluid.

Strut fluid level checked by?. Hydraulic gauge. Deflate strut and fill to filler plug flush. Visually inspect only.

Hydraulic system using mineral oil uses what type of seals?. Neoprene or synthetic. Natural rubber. Metal gaskets.

Proper inflation of strut determined by?. Mark on inner sleeve. Manufacturer chart. Feel test.

Snubbers at pressure gauges prevent?. Pressure drop. Rapid gauge fluctuations. Fluid contamination.

Cabin pressurization modes?. Isobaric, differential, unpressurized. Low, medium, high. Slow, fast, emergency.

In isobaric mode, cabin pressure maintained by?. Regulator bellows movement. Manual valve. Engine speed.

In differential mode, reference pressure is vented by?. Outflow valve. Differential metering valve. Air-cycle turbine.

If cabin rate of climb too high?. Outflow valve closes faster. Open emergency valve. Reduce engine power.

Air-cycle cooling system produces cold air by?. Extracting heat via expansion turbine. Cooling fins. Engine bleed air only.

Evacuation of freon system purpose?. Remove moisture. Remove gas. Add lubricant.

Pressure controller controls pressurization in?. Differential mode. Isobaric mode. Unpressurized mode.
