1. Where is the flow meter of the fuel dispenser located? Flow meters are usually installed at the bottom of the fuel dispenser. The flow meters commonly used in domestic fuel dispensers have their inlet located on the top cover. When the pressure oil enters the distribution chamber, it will directly impact the distributor, resulting in uncertain factors such as turbulence and affecting the measurement accuracy. Requirements for using fuel dispensers. Before using the fuel dispenser, check if it is operating normally and if there are any leaks, and keep the dispenser clean. Refueling machines without a certificate of conformity issued by the technical supervision department, or measuring instruments without lead seals from the technical supervision department, or with incomplete lead seals, are not allowed to refuel users. After turning off the car, open the fuel tank cap before starting the fuel dispenser. When refueling, the fuel gun must not be handed over to the customer to refuel on their own. During the refueling process, attention should be paid to the working condition of the machine (sound, etc.) and the display of oil products. If any abnormalities are found, the machine should be stopped for inspection and the fault should be eliminated before continuing to use. The oil gun should be handled with care, and the refueling hose should not be twisted or forcefully stretched. The oil gun should not be used to support the body to prevent damage to the equipment.

2. What instruments do airplane pilots need to check when operating?

When operating an airplane, pilots need to focus on monitoring six types of core instruments and dynamically adjust the priority according to the flight phase.

1 Basic

flight instruments • Airspeed gauge: displays current ground speed (GS) and indicated airspeed (IAS), with a ± 5 knot error during cruise phase. J-lift range • Altimeter: uses millibars (hPa) and feet dual units, with an error requirement of ≤ 50 feet during approach • Attitude gauge (ADI): real-time display of pitch/roll angle, abnormal attitude will trigger a red warning box • Heading indicator (HSI): integrates magnetic heading and VOR/ILS navigation signals. 2. Engine instrument cluster • N1 tachometer: Contemporary turbofan engine cruising N1 is usually maintained at 85-92% • EGT gauge: LEAP engine limit temperature of A320neo is 950 ℃ • Fuel flow meter: B787-9 during transoceanic flight The typical fuel consumption is 5.8 tons/hour Navigation system display • Primary Flight Display (PFD): integrates all basic flight parameters, Airbus A350 adopts a 38cm LCD screen • Navigation Display (ND): switchable compass/plan/approach mode, Boeing 787 supports 360 ° panoramic display • Terrain Warning (TAWS): automatically updates surrounding terrain data every 6-15 seconds Aircraft status monitoring • Hydraulic system pressure gauge: A380 is equipped with 3 independent systems, with a normal working pressure of 3000psi • Cabin pressure altimeter: An alarm will be triggered when the cabin altitude exceeds 8000 feet • Flap position indicator: B777 maximum flap extension angle is 30 degrees 5 Alarm device • Main warning light (red): Serious malfunction requiring immediate action • Main warning light (amber): Attention required but not emergency • ECAM/EICAS: Airbus/Boeing adopt graded alarm logic 6 Auxiliary instruments • Time Potato Virtual Clock (UTC): ICAO requires cockpit clock error ≤ 30 seconds/month • Temperature gauge:
