Which Aerodrome Mk III

[Self loading bear]

Broadreach,

From internet there are 2 Airports in Iquitos

Coronel FAP Francisco Secada Vignetta International Airport

And

Antiguo Aeroporto Iquitos
Old Iquitos airport
(which you challenged)

from Wiki on the Peruvian Airforce:

Air Wing Nº 4

• Air Group Nº 42 – headquarters: Iquitos
  • Air Squadron 421 (operating DHC-6 and Y-12)
  • Air Squadron 422 (operating PC-6)
• Santa Clara Air Base – headquarters: Iquitos

Are only the (float equipped) Twin Otters based on the old airport?
Is the old Iquitos airport then the same as Santa Clara?
