5 - Equations 7 - 1 and 7- 2 approximate the distance from the threshold to the first exit.
D= Dtd +De (7-1)
Where: D = the distance from the runway threshold to the exits.
Dtd = distance from the runway threshold to the point where the
aircraft touches down.
De = the distance from the touchdown point to the exit.
De = 푽풕풅
ퟐ−푽풆ퟐ
ퟐ풂^ (^7 - 2)^
Where Vtd = aircraft speed at touchdown
Ve = exit speed of the aircraft
a= deceleration of the aircraft on the runway.
6 - To determine a preliminary location of the exit taxiways that accommodate all aircraft
under the ADG VI; the location requirements for the largest and smallest aircraft in the
design group were approximated using Equations 7 - 1 and 7 - 2. Table 7- 17 summarize the
properties of design aircraft of the exit taxiways.
