(b) A cylinder head temperature indicator for each air-cooled engine.
(c) A fuel pressure indicator for each engine.
(d) A fuel flowmeter or fuel mixture indicator for each engine not equipped with an automatic altitude mixture control.
(e) A means for indicating fuel quantity in each fuel tank to be used.
(f) A manifold pressure indicator for each engine.
(g) An oil pressure indicator for each engine.
(h) An oil quantity indicator for each oil tank when a transfer or separate oil reserve supply is used.
(i) An oil-in temperature indicator for each engine.
(j) A tachometer for each engine.
(k) An independent fuel pressure warning device for each engine or a master warning device for all engines with a means for isolating the individual warning circuits from the master warning device.
(l) A device for each reversible propeller, to indicate to the pilot when the propeller is in reverse pitch, that complies with the following:
