† The essential difference between the Lancaster Marks I and III was in the power units, the former incorporating Merlin XX engines, the latter Merlin 28 (identical with the XX) built in America by Packard.

† Performance data in this table relate to the aircraft operating in a short-range fighter role. When bombs, rockets or drop tanks were added these figures were reduced. The bomb weights are those which could be carried when the aircraft operated as a fighter-bomber.

(i) MAXIMUM SPEED was only possible for an extremely limited period. Apart from tactical manoeuvring, bomber and fighter aircraft, in the main, flew at speeds between ‘most economical cruising’ and ‘maximum continuous cruising’. Varying with the different aircraft, these speeds were respectively between 55-80% and 80-90% of the maximum speed.
(ii) SERVICE CEILING. The height at which the rate of climb has a certain defined low value (in British practice 100 feet per minute) . Ceilings quoted are for aircraft with full load.
(iii) RANGE AND ASSOCIATED BOMB LOAD. The main purpose of this table is to give some idea of the relative performances of the various aircraft. The figures quoted relate to aircraft flying at ‘most economical cruising’ speed at the specified height, i.e. the speed and height at which the greatest range could be obtained. Allowance is made for take-off but not for landing, the range quoted being the maximum distance the aircraft could cover in still air ‘flying to dry tanks’. Furthermore in the planning of operations a reduction of range of about 25% had to be made for navigational errors, tactical manoeuvring, weather conditions and other factors.
(iv) ENDURANCE. The time an aircraft can continue flying under given conditions without refuelling. This being a vital factor of Coastal Command operations an economical cruising speed, consistent with maximum safe endurance as determined under normal operational conditions, is quoted.
(v) A number of Liberators Marks III and V were modified to achieve a performance similar to that of the VLR Liberator Mark I.
(vi) The Catalina Mark III (amphibian) was known as the Canso.
(vii) ABBREVIATIONS. (N/F) Night-Fighter; (L/F) Low Flying; (R.P.) Rocket Projectile; (F.B.) Flying Boat; (T/B) Torpedo-Bomber; (VLR) Very Long Range.
