single-frequency approach

A service provided under a letter of agreement to military single-piloted turbojet aircraft that permits the use of a single UHF (ultrahigh frequency) frequency during the approach for landing. Pilots will not normally be required to change the frequency from the beginning of the approach to touchdown, but those conducting an en route descent are required to change the frequency when control is transferred from the air route traffic control center to the terminal facility.

Detecting point-like sources of unknown frequency spectra

I thought i was prepared

Consider the different scenarios that may be happening at the same time: GCA or TACAN traffic (on single-frequency approaches); field-carrier-landing-practice (FCLP) aircraft (usually on their own frequency); overhead or straight-in traffic on the normal tower frequency, VFR transition aircraft on VHF; and rotary-wing aircraft, at fixed-wing bases, flying their own VFR course rules.

I almost hit a dolphin: while I leveled the wings, I saw the helicopter pass down our right side. He still was in a hover at the approach end of the runaway, and I was at eye level with his main rotor
