• Turn on electric instruments if applicable. 

• Check gauges for proper ranges (oil pressure, revolutions per minute (rpm), charging voltage, engine temperatures within ranges, etc.) 

• Continue to monitor area and shut down engine if any person or animal approaches. 

A relatively low rpm setting is recommended immediately following engine start. This is typically a slight increase in the throttle to keep the engine running smoothly. It is not recommended to allow the rpm to race immediately after a 

start with a cold engine, as there is insuffi cient lubrication until the oil pressure rises on four-stroke engines, and unequal heating on two-stroke engines. In freezing temperatures, the engine is also exposed to potential mechanical distress until it warms and normal internal operating clearances are reached. 

On four-stroke engines, as soon as the engine is started, the oil pressure should be checked. If it does not rise to the manufacturer’s specified value, the engine may not be receiving proper lubrication and should be shut down immediately to prevent serious damage. 

##  Taxiing 

Since an aircraft is moved under its own power between the startup area and the runway, the pilot must thoroughly understand and be proficient in taxi procedures. When the brakes are first released and the aircraft starts to roll, the brakes should be tested immediately for proper operation. Applying power to start the WSC aircraft moving forward slowly, then retarding the throttle and simultaneously applying pressure smoothly on the brake may be needed to accomplish this. If braking action is unsatisfactory, the engine should be shut down immediately. 

When yellow taxiway centerline stripes are provided, they should be followed unless it becomes necessary to deviate to clear aircraft or obstructions. [Figure 5-65]

An awareness of other aircraft that are taking off, landing, or taxiing, and consideration for the right-of-way of others is essential to safety. When taxiing, the pilot’s eyes should be looking outside the aircraft, to the sides, as well as the front. The pilot must be aware of the entire area around the aircraft to ensure that it clears all obstructions, people, animals, and other aircraft. If at any time there is doubt about the clearance from an object, the pilot should stop the aircraft and check
