737 NG

The NG engine instruments are normally displayed on the center forward panel upper and lower display units. The choice of gauges displayed is a customer option.. Many NG's operators choose to have most of the parameters hidden after engine start. If an abnormality arises, it will automatically display thereby alerting the crew to the problem.


737-3/4/500

Most of the 737-3/4/500's had this Engine Instrument System (EIS) primary and secondary panel made by Smiths Industries. The primary panel had the usual N1, EGT, N2 and Fuel flow/used. The secondary panel had the oil pressure, temperature and quantity (digital only), vibration and also included the hydraulic pressure and quantity (digital only) from the F/O's instrument panel.

Early 737-300

This "Round Dial" 737-300 is distinguishable from a -1/200 by not having an EPR gauge and the inclusion of a vibration gauge. The hydraulic quantity and pressure gauges are still outboard of the gear lever.

 


737-200dv

The 737-1/200 had JT8D engines, placarded here as -9A's. EPR was used for power settings instead of N1 and the panel on the right is where EPR was set for the autothrottle along with A/T mode - CRZ / CLIMB / CONT / GA. The sequence of primary engine instruments was: EPR, N1, EGT, N2, Fuel flow. The secondary instruments were oil pressure, oil temperature, oil quantity. Notice that there was no vibration gauge and the hydraulic pressure gauge was to the right of the gear lever. The Reverser Unlocked lights were grouped with the other engine warnings.

The two INOP stickers are for the GRAVEL PROTECT lights which blew bleed air from a probe ahead of the engine cowl to stop vortices lifting debris into the engine. See unpaved strip kit.

 


727-200Adv

Even older is this 727-200Adv panel with N1, EPR, EGT, N2, FF and no oil or hydraulic gauges.
