Ladder Pipe Reach

Aerial geometry combined with master-stream forward reach.

Run the calculator

Example

You enter

Set angle (degrees) 70
Extension (ft) 100
Nozzle type smooth_bore_1_75
Nozzle pressure (psi) 80

You get

Horizontal ladder reach 34.2 ft
Vertical ladder reach 94.0 ft
Stream reach 90 ft
Horizontal stream (ft) 77.94
Total horizontal reach 112.1 ft

Details, formula, and sources

Effective reach = aerial-tip horizontal projection + master-stream forward reach (from master-stream tile). Combines aerial-ladder geometry with NFPA 1965 nozzle reach.

NFPA 1901 + NFPA 1965 by name; NFA tactical-aerial training materials.
