David W. Wragg classifies air services as medium-haul being between 1,600–4,000 km; 900–2,200 nmi; short-haul as being shorter and long-haul as being longer. [11] David Crocker defines short-haul flights as shorter than 1,000 km (540 nmi), [ 12 ] : 208 and long-haul as the opposite.
The logarithmic term with weight ratios is replaced by the direct ratio between / = where is the energy per mass of the battery (e.g. 150-200 Wh/kg for Li-ion batteries), the total efficiency (typically 0.7-0.8 for batteries, motor, gearbox and propeller), / lift over drag (typically around 18), and the weight ratio / typically around 0.3.

The airport has three intersecting runways - 1/19 (7169' x 150' / 2185m x 46m), 15/33 (5204' x 150' / 1586m x 46m) and 4/22 (5000' x 150' / 1524m x 46m). All aircraft typically use Runway 1/19, although Commuter and General Aviation aircraft sometimes use Runway 15/33, when requested by ATC due to traffic volume or when winds favor that runway.
An aircraft with drop tanks will have a greater radius of action than the same one without. In military aviation, the combat radius of an aircraft is often given with its mission profile (without in-air refueling). For example: The F-16 Fighting Falcon's combat radius is 550 km (340 mi) on a hi-lo-hi mission with six 450 kg (1,000 lb) bombs.
If a pilot is flying a 120-mile leg and finds after 30 miles that he is two miles left of track, then he has flown 4° left of his intended track, i.e. 2 × 60/30. left of track. Changing the heading four degrees right will now bring him to parallel the intended track. At that point he still has 90 miles to his next waypoint.
