AOM Procedure
Example 1: AOMP can MEET the SID climb gradient requirement
Given: 1.SID required minimum climb gradient 5.9 % to 3,000 ft, 2. TOW: 420,000 lbs, 3. TFLEX: 55 °C (ISA+40 °C),
4. Airport pressure altitude: 1,000 ft,
check whether meet the SID requirement?
Solution:
Use table 1 to check average climb gradient > SID requirement.
1. Use Table 1, input TOW: 420 klb =>the average climb gradient 8.1 %,
2. Apply TFLEX correction(-0.2* = -0.8) and airport pressure altitude correction (-0.3* =-0.3),
3. 8.1-0.8-0.3=7.0% >SID5.9% =>Follow AOMP can meet SID requirement.
Example 2: If Table1 can’t meet SID, Adjust Acceleration Altitude
Given: 1.SID required minimum climb gradient 6.5 % to 4,000 ft, 2. TOW: 507,000 lbs, 3. OAT: 35 °C(ISA+20°C) & TOGA Power 4. Airport pressure altitude: 1,000 ft,
check whether meet the SID requirement?
Solution:
1. Use Table 1, input TOW: 507 klb => the average climb gradient 5.7 %,
2. Apply OAT correction (-0.1* =-0.2) and airport pressure altitude correction (-0.2* =-0.2),
3. The result is 5.7-0.2-0.2=5.3 % < SID requirement 6.5%.
4. SID requirement is up to 4,000 ft, then check Table 2 & consider to Accelerate until 4,000 ft.
5. Use Table 2, input TOW: 507 klb & Acc alt 4,000’ => gradient 8.1 %,
6. Apply OAT correction (-0.1* =-0.2) and airport pressure altitude correction
(-0.2* =-0.2),
7. The result is 8.1-0.2-0.2=7.7 % > SID 6.5 % => acceleration at 4,000’ can meet the SID requirement.
NADP1
Example 3: If AOMP can’t meet SID, try NADP1
Solution:
Given: 1. SID required minimum climb gradient 9.0 % to 3,000 ft, 2. TOW: 500,000 lbs, 3. TFLEX: 35 °C (ISA+20 °C),
4. Airport pressure altitude: Sea level
check whether meet the SID requirement?
1. AOMP(BothTable1&2)can’tmeetSID,thentryNADP1procedure.(1,500 Climb Power/ 3,000 Acceleration)
2. Use Table 3, input TOW: 500 klb => gradient 9.7 %, and apply TFLEX correction(-0.1* =-0.2),(Sea level =>No Alt correction)
3. 9.7-0.2=9.5% >SID 9.0 % =>Conduct NADP1 can meet the SID requirement.
Example 4: If AOMP & NADP1 can’t meet SID => Advise ATC
