Sa chás sin, le haghaidh chéim an éirí de thalamh, is é V1 an luas tosaigh, is é V2 luas an éirí de thalamh, is é nTO líon na ndeighleog um éirí de thalamh agus is é sTO fad coibhéiseach an éirí de thalamh.
In this case, for the takeoff phase, V1 is initial speed, V2 is the takeoff speed, nTO is the number of takeoff segment and sTO is the equivalent takeoff distance.
Le haghaidh fhad coibhéiseach an éirí de thalamh sTO (féach Aguisín B) agus luas éirí de thalamh V1 agus luas éirí de thalamh VTO is ionann líon nTO na ndeighleog don rothlúchán talún agus
For equivalent takeoff distance sTO (see Appendix B) and takeoff speed V1 and takeoff speed VTO the number nTO of segments for the ground roll is
Sampla: Le haghaidh fad éirí de thalamh sTO = 1600 m, V1=0m/s agus V2 = 75 m/s, tugann sé sin nTO = 8 ndeighleog d’fhaid idir 25 agus 375 méadar (féach Fíor 2.7.g):
Example: For a takeoff distance sTO = 1600 m, V1 = 0m/s and V2 = 75 m/s, this yields nTO = 8 segments with lengths ranging from 25 to 375 metres (see Figure 2.7.g):
Sa chás sin, le haghaidh chéim an éirí de thalamh, is é V1 an luas tosaigh Vinit, is é V2 luas an éirí de thalamh VTO, is é n líon na ndeighleog um éirí de thalamh nTO, is é s an fad coibhéiseach an éirí de thalamh sTO agus is é sk fad sTO,k na deighleoige k (1[Siombal]k[Siombal]n).
In this case, for the takeoff phase, V1 is initial speed Vinit, V2 is the takeoff speed VTO, n is the number of takeoff segment nTO, s is the equivalent takeoff distance sTO and sk is the length sTO,k of segment k (1[Symbol]k[Symbol]n).
