Dave has received his weather information  for an afternoon flight, and finds the winds  are forecast to stay above 7 mph until just  before sunset. He goes ahead with planning  the flight, believing the winds will decrease,  and will soon be going out to the launch site  to start preparations for launch. In this example, Dave is in the  Observe part of the decision cycle. He will continue  to  Observe  until he detects a condition that  would cause him to cancel the flight. Dave  has completed a full cycle of the OODA  Loop, but has returned to the  Observe node to continue to monitor the weather. Upon reaching the launch site, Dave checks  the winds using a pibal and finds that winds  are decreasing. He believes a flight can be  safely conducted, and goes ahead with his  launch plans. After launch, Dave finds that  the winds are in a direction that is not quite  what was forecast, and are taking him into  an area with few good landing areas. He  continues the flight, and watches the  direction closely to detect any further  change of direction. In this example, Dave has completed an  OODA decision-making cycle, and has  returned to the  Orient node. He will  continue to monitor the situation, being  aware of changes, and is prepared to make  a decision when the situation warrants. Twenty minutes into the flight, Dave notices  frost forming on the outside of the fuel fitting  leading to the burner. Since he cannot  tighten the fitting (it is a fixed fitting), he  decides to shut off the fuel on that side, vent  the line, and land as soon as practicable in  accordance with the established “emer- gency” procedure. Here, Dave has completed an entire  Decision  cycle in a very short time due to  the circumstances of the situation. He will  now move to the  Act node, and will take  action to resolve the issue before it causes  danger to him or his passenger. While making an approach to land, Dave’s  passenger, Pat, alerts him to powerlines  running across the near side of the small  field. Dave evaluates his approach and  Acts to land accordingly, knowing that  winds may shift somewhat as he descends.  He touches down well past the powerlines,  never having put him or his passenger at  risk, and has an uneventful deflation. Dave again completed an OODA Loop  decision-making cycle. Had there been an  indication that the approach could not be  safely completed, Dave could have made a  decision to abort the landing  (Decide),  and  then performed an  Act  to effect a change.

While these examples show a sequence, this is not always the case; the OODA Loop cycles may overlap in any stage of  execution. 1-12
