Huckerby}16.11.33 re AERO ENGINE FUEL TO SPECIFICATIONS D.T.D.224 & 230 ---------------------------------------------------- With reference to your memo BY/EM3/J.15.11.33, when special fuel is used for type test it is possible, and we will arrange accordingly, to specify the purpose for which the fuel is required. In quite a number of cases, however, type tests are run on standard fuel, which is now D.T.D.224, and we shall be using this fuel for type tests and production tests concurrently. In view of this it would appear that all standard D.T.D.224 fuel should be within the range of + 1 of the octane value, which is specified for type tests. EP{G.
