9.5. In-flight Checks.

p. 173

9.5.1. Objective. Ensure the formation conducts periodic checks of aircraft systems IAW T.O. 1T-6A-1.

p. 173

9.5.2. Description. Number 1 and number 2 perform the checklist appropriate for the phase of flight (Ops Check, Descent Check, etc.).

p. 173

9.5.3. Procedure. Use the intraflight radio to initiate checks if practical. Use visual signals if formation spacing allows or if radio traffic inhibits the use of the intraflight radio. If forced to turn during a check, number 1 should call the turn and ensure number 2 is attentive before turning. Number 2 resumes the check after the turn is complete. In-flight checks are normally accomplished in the following manner:

p. 173

9.5.3.1. Number 1. Direct the check (visually or via radio call). To confirm the check has been accomplished, wingman will mimic lead by responding visually or on the radio. If using radios, both members will transmit call sign and OBOGS status (for the Climb Check) or call sign and total fuel (for the Ops Check and Descent Check).”

p. 173

9.5.3.1.1. Example: “Texan, climb check.” (“2”) “Texan 1, OBOGS good” or “Texan, ops check.” (“2”) “Texan 1, 800” (“Texan 2, same”)

p. 174

9.5.3.1.2. It is permissible to combine multiple checks into a single directive or radio call.

p. 174

9.5.3.1.3. Example: “Texan, climb check, ops check.” (“2”) “Texan 1, OBOGS good, 800” (“Texan 2, OBOGS good, 700”)

p. 174

9.5.3.1.4. “It is also permissible to perform a check individually before directing the formation to accomplish the check. If the status of the completed check is known, number 1 may include it in the radio call.

p. 174

9.5.3.1.5. Example: “Texan, climb check, Texan 1, OBOGS good” (“Texan 2, OBOGS good”)

p. 174

9.5.3.2. Number 2. Number 2 will acknowledge number 1’s visual signal or radio call to initiate checks, consider loosening the formation spacing (up to route) and perform the appropriate checklist items. If in fingertip and weather prevents loosening spacing, inform number 1 (e.g. “Texan 2 unable, weather”) and accomplish checks as soon as VMC conditions permit. Once check is complete, resume fingertip spacing (or as directed by number 1). Accomplish checks expeditiously, checking position on number 1 frequently. Prioritize tasks appropriately: maintain position first and accomplish checklist items as workload permits. During turns, consider maintaining position and resuming the check after the turn is complete.
