Length of hose remaining out of ar pod, runway surface and likelihood of snagging hose on landing, location and rigging of the arresting gear, usable runway length, stability of hose and drogue, and location of landing if hose was guillotined
Aerial refueling procedure warnings:
-Dont transmit on hf radios when receiver is in contact or attempting to plug——dont select master power or hyd power off during hose transitions (hose may depart a/c)—-if you let low speed drogues out above 120kts they may depart the a/c reduce speed rapidly
Special considerations IRT fuse tank with less than 20,000lbs of fuel?
If it has less than 20,000lbs of fuel the external tanks must be empty. IF the external tanks are not empty you can only fly straight and level
