Quid,
I have to say that I dont agree with you. For your situation, can you explain what you are going to do on an engine out approach when the single runway before you gets blocked? Or if you havent become visual at the MAP?
We use the following rules prior to takeoff. Landing weight must be based on:
1: Certificated Structural Landing Weight.
2: Approach Climb/ Landing Climb Limit Weight.
3: Field Length Limit Weight using the 60%/40% rule.
If the crew need to return after landing, they only need to comply with:
1: Approach Climb/ Landing Climb Limit Weight.
2: Field Length Limit weight using 100% of the runway length.
These rules allow for a landing without running off the end of the runway and also allow for a missed approach if needed.
Obviously these rules dont apply to the MUST GET DOWN NOW situation, but in general they work.
Can I ask what others are doing?
Thanks.
