How do you determine if Non Standard Take off procedures are applicable to your departure aerodrome? Look in the TLA. 23 Let’s go there now. Vol 14. Table of Contents NON STANDARD TAKE OFF PROCEDURES
24
Determine if IFR take off Minima is Non- Standard for Birmingham, ALDetermine if IFR take off Minima is Non- Standard for Birmingham, AL Non-standard T/O minima does exist at Birmingham, on pg. XXIV Refer to the TLA to determine if Non- Standard Take off procedures apply. 24 Vol 14, pg III. TABLE of CONTENTS XXIV
25
Another method to determine if an airport has Non- Standard Take-off procedures is look for a symbol in the Pilot Briefing Section of any IAP At your departure airfield. If there is a symbol you must refer to the TAKE OFF procedures listed in the front of this FLIP for specifics. T T 25 Vol 14 Let’s go there now. Pg. XXIV
26
26 What are T/O minimums if you are departing from RWY 6 at Birmingham?
27
27 What are T/O minimums if you are departing from RWY 6 at Birmingham? You must have at least 300 – 1 ¾ with min climb of 282 ft/NM to 1800. UNLESS..*.. Or std if your climb gradient is at least 421 ft per NM to 1800. If your gradient is at least 421 ft/nm then your take off minima is STD, which is: 100 - 1/4 or 0 – 0. Let’s review E6B procedures on how to convert feet per nm to feet per min.
28
Use E6B to compute Rate of Climb, given Gradient and Ground Speed 1. Set speed index at 80 GS G/S: 80kt Gradient: 421 f/nm 2. Locate 421 f/nm on inner ring 3.Determine FPM. It’s on the outer ring opposite 421 f/nm. 560 FPM
29
29 What are T/O minimums if departing from RWY 24? There is no non-standard T/O minimums published for RWY 24 therefore T/O minimums are 100-1/4 or 0-0. Note there is a published minimum altitude before making turns. 2200 feet.

73
Factors that can raise visibility requirements Height Above Touchdown (HAT) Final Approach Course Runway Alignment Effect of Obstacles Length of final approach
74
Approach Light Systems (ALS) Authorized Approach Light System will permit an approach to be certified with visibility minimums below the basic design requirements.
75
Inoperative Components When the approach lights are out of service all approaches will normally revert back to the minimums that would have applied had the lighting system never been installed. Therefore, we as the pilot must adjust the weather planning visibility using the Inoperative Component Chart or follow the instructions in the Pilot’s Briefing section.
76
76 INOP Components minima Adjustments. Page XX. Page A1 in the TPP DoD FLIP p. XX
77
77 SCENARIO: When planning an IFR mission, you check NOTAMS, and determine that the ALSF 1 approach lights are inoperative for the runway that you plan to execute a VOR approach to.
78
78 The INOP Components Table requires an adjustment to Minimums when the ALSF-1 lighting system is inop. 1. Locate the Table that applies to the type Approach to be flown. VOR in our example 2. Locate the Line that applies to the INOP component, ALSF-1, and your approach category A. 3.Determine the amount to Increase Planning Minimum Visibility In this instance we will add ½ mile visibility to our planning minimums
79
79 We determine from the IAP that the published planning minimums for the VOR approach we intend to fly is listed as: (500 – ¾) We determined that we need to increase planning visibility by ½ mile from Table (3) Next we will add ½ to ¾. ½ + ¾ 1 ¼ Final step, we will reduce 1 ¼ by 50% to determine our new HELICOPTER planning minimum visibility. 1 ¼ reduced by 50% = 5/8 sm. Adjusted planning minimums are (500 – 5/8) due to inop ALSF-1
80
80 CAUTION Add the value determined in the INOP components Table to your planning minima before you reduce by 50% ! ! ! ! ! ! ! Ref. AR 95-1, 5-2, c., (5)
81
81 In this IAP CATs A&B increase vis to 1 sm when the ALS (approach lighting system) is inop. If the minima adjustment procedure is listed in the PILOT BRIEFING section it is not necessary to refer to the INOP Components Table.
