07 - APPROACH / LANDING / GO AROUND

SR-71-A NORMAL PROCEDURES

ABBREVIATED CHECKLIST



APPROACH
  1. Display mode select - SET (ANS/TACAN/ILS)
  2. Defog - SET
  3. Altimeter - SET
  4. INS altitude - UPDATE (RSO)
  5. Crossfeed - OPEN
  6. Brake switches - SET, ANTISKID ON
  7. Below Mach 0.5, Limiter - PULLED & LIGHT OFF
  8. UHF power - SET
  9. Defog - SET
  10. Landing light - ON

BEFORE LANDING
  1. Approach and landing speed - COMPUTED
  2. CG - CHECKED (between 17%-22% for all subsonic operations)
  3. Gear - 5-10 miles from the runway, MAX 300 KIAS -DOWN & CHECKED
  4. Hydraulic pressure - CHECK
  5. Right refrig - OFF
  6. Ckpit air - OFF (fwd, RSO).
  7. Annunciator panel - CHECKED



LANDING
  1. Chute - DEPLOY
  2. Steering - ENGAGE
  3. Brakes - CHECKED
  4. Chute - JETTISON (over 55 knots)

TOUCH AND GO
  1. Final approach - 190 KIAS
  2. Touchdown - 170 KIAS

GO AROUND
  1. Throttles - MILITARY THRUST (Maximum thrust is necessary)
  2. Landing gear lever - UP (after positive rate of climb is established)

NOTE I:
The excess thrust available to perform a go-around varies with airspeed, gross weight, airplane configuration, field elevation and ambient temperature. As extremes of these variables are approached, the ability to perform a successful go-around with military thrust decreases, thus requiring afterburner. Refer to appendix for charts showing variation in performance to be expected with changes in these operating conditions.

NOTE II:
Fuel required for a missed approach and instrument go-around (typical GCA pattern) is approximately 3,000 pounds. A closed pattern go-around requires approximately 1,000 pounds.

WARNING
DO NOT ATTEMPT A GO-AROUND AFTER DRAG CHUTE CONTROL HAS BEEN ACTUATED.
