Virtual Museum - P-40 Instrument Panels and Instruments

Ref. No. 931.  ORIGINAL CURTISS WARHAWK P-40N-1 INSTRUMENT PANEL.  The P-40N-1 series was the fastest production model P-40 ever built.  This was on account of a weight reduction programme.  One of the items to be trimmed was the instrument panel, which had the Artificial Horizon and Directional Gyro removed.  With these gone, there was no need for a suction instrument either and all three of these gauges were deleted from the panel (see above).  The RNZAF used this batch of aircraft in air-to-air combat over the Solomon Islands and New Guinea (see Chris Rudge's book Air-to-Air here for an account of these combats).  Without the blind flying instruments, the P-40N-1 wasn't popular with pilots, who found their usefulness on operations limited.  As a result,  the blind flying instruments were reinstated in the P-40N-25 block aircraft but the RNZAF were never issued with this variant. A sub-panel was located below the B-16 compass in the space shown (see above) and consisted of an oxygen pressure gauge and oxygen blinker.

ORIGINAL P-40E INSTRUMENT PANEL. This instrument panel came from an RCAF aircraft that was scrapped in Vulcan, Canada in 1946.   Most of the instruments shown here were with the panel when it was scrapped.   This instrumentation combination is mostly the same as was called for in the Curtiss technical drawings for the British-Commonwealth P-40E's.   Most of these instruments were manufacturered by Pioneer.  Notice the millibar altimeter, as used in British-Commonwealth aircraft.   D Collier

Ref. No. 899.  P-40 KITTYHAWK UNDERCARRIAGE INDICATOR.  Data plate reads “Indicator. Position.  Type A-3. Order No. AC-25808. Mfrs. Part No. Model 8DJ17AAL Sub 4. Serial No. AC42-428277. Spec. No. 27375. 24 volts. General Electric.”

P-40N WING FUEL TANK GAUGE:  87-44-536.    This fuel gauge design is typical for most P-40 models, the obvious difference between the various models being the fuel quantity amount given on the face of the gauge.  This gauge mounted on the top of the wing, which was the cockpit floor.  Attached to the backside is a  mechanical float that rides in a 12-inch-long tube which had a spiraled slot cut in it.   In the slot rode a tab that rotated the indicating needle around the face of the gauge.  D Collier
