Some more 'eye glazing' material re G/S angle.
COMCARAIRWING SEVEN INSTRUCTION 1520.1N | Subj: LANDING SIGNAL OFFICER TRAINING/CARRIER LANDING SAFETY PROGRAMhttp://www.cvw7.navy.mil/inc/cmodules/dms/download-rel.php?secid=99&id=0&filesystem_id=7199(4) Glide slope. When using the FLOLS/IFLOLS, under normal conditions the following basic angles will be used.
BASIC ANGLE Relative Head Wind
3.5 degrees <33 kts
3.75 degrees 33-37 kts (Hornets 33Klbs)
4.0 degrees >37 kts sustained (Hornets 33Klbs/half flaps)

(5) Wind. During normal operations wind calls will be made periodically. During “ZIP LIP,” wind calls will not be made if WOD is 25-30 knots. It should be emphasised that ARB 33-12 Series for MARK 7 MOD 3 arresting gear states that “recovery headwinds” (RHW) are based on 59 degrees Fahrenheit. For temperatures above 59°F, RHWs shall be increased using the density altitude tables in the 33/34 series. ARB 33-12 Series also recommends that 6 knots be added to RHWs to compensate for variations in WOD velocity and direction, pilot technique, approach speeds, turbulence, and to minimize loads on the aircraft and/or arresting system.

(9) Groove length. Proper groove length is 15-18 seconds, 19-21 seconds will be grades as “little long in the groove.” If it is required to waveoff a LIG aircraft it will be grades as 2.0 points (WOP).
-
(10) Hook skip bolters. Hook skip bolters may or may not count against boarding rate. If the hook skip was pilot induced i.e., fast nose down or dropped nose to land, then the hook skip shall be graded as a bolter and count against boarding rate. If the hook skip was not pilot induced, the pass will be graded as a "no-count" and shall not be counted against boarding rate.
-
m. TRENDS. Squadron LSOs shall keep current trend data on all squadron pilots. Trends may be recorded by hand using OPNAV form 3760/71 (Rev. 7-71) or by trend output from the APARTS computer program. At a minimum, Squadron LSOs shall debrief pilot trends prior to each at-sea period during work-ups. On extended deployments, trend debriefs shall be done at least monthly. Pilots shall initial and date the trend sheet each time they are reviewed. Trend files shall be maintained on each pilot. The file should include FRS trends (for nuggets) and contain all at-sea trends for the duration of the pilot's squadron tour.

k. FCLP. ...Test line-up and waveoff shall be initiated at least once per pilot per FCLP period.”
