Available for floatplanes and landplanes
, the prop delivers enhanced performance in both configurations.
Only three examples of the Potez 540 TOE, the colonial version of the Potez 540 bomber, were built and apart from a small number of standard Potez 540s retired from bomber units there were no other military landplanes
stationed abroad capable of carrying substantial loads either of personnel or of freight: it was only in September 1940, after France's surrender, that the Armee de I'Air established its first dedicated transport units.
Ironically it had been landplanes
serving in the Fleet Air Detachment, Atlantic Fleet--their operations consisting of flights from makeshift wooden platforms constructed on battleships--that helped point the way toward construction of the Navy's carriers.
1935: Shannon is chosen by the Government as a "suitable base for the operation of seaplanes and landplanes
on a transatlantic service".
Since speed had already been discounted, the selection of a design type inherently slower (and therefore less efficient) than landplanes did not matter.
The flying boats, wrote Johnston, could never be more efficient than landplanes, and they were no safer.
These typically range from $0 to $2500 for landplanes
and are substantially more for amphibians, frequently as much as 10 percent of the airplane's value.
Its problem was that by the time it was developed much smaller landplanes
could be built to do that, too.
When the navy risked denuding the Solomons of everything except for floatplanes and a handful of landplanes
it could assemble as many as forty-five medium bombers and over sixty Type Zero fighters for operations from Rabaul and Kavieng for short periods.
Planned for delivery starting in 2015, the new aircraft will be configured as standard 19-passenger commercial landplanes
and put into operation as domestic carriers across the Seychelles archipelago.
In 1917, of 168 sightings by British aircraft of German submarines, twenty-eight were by naval airships, sixty-eight by flying boats, sixty-six by floatplanes, and only six by landplanes.
Floatplanes and flying boats making sorties from coastal bases were, from the nature of their construction, fatally inferior in speed and maneuverability to landplanes flying from bases a little further inland.
