§ 91.1039 

(2) The airplane is landed on the most 

suitable runway considering the prob-
able wind velocity and direction and 
the ground handling characteristics of 
that airplane, and considering other 
conditions such as landing aids and ter-
rain. 

(c) A program manager or other per-

son flying a turbine engine powered 
large transport category airplane on a 
program flight may permit that air-
plane to take off at a weight in excess 
of that allowed by paragraph (b) of this 
section if all of the following condi-
tions exist: 

(1) The operation is conducted in ac-

cordance with an approved Destination 
Airport Analysis in that person’s pro-
gram operating manual that contains 
the elements listed in § 91.1025(o). 

(2) The airplane’s weight on arrival, 

allowing for normal consumption of 
fuel and oil in flight (in accordance 
with the landing distance in the Air-
plane Flight Manual for the elevation 
of the destination airport and the wind 
conditions expected there at the time 
of landing), would allow a full stop 
landing at the intended destination air-
port within 80 percent of the effective 
length of each runway described below 
from a point 50 feet above the intersec-
tion of the obstruction clearance plane 
and the runway. For the purpose of de-
termining the allowable landing weight 
at the destination airport, the fol-
lowing is assumed: 

(i) The airplane is landed on the most 

favorable runway and in the most fa-
vorable direction, in still air. 

(ii) The airplane is landed on the 

most suitable runway considering the 
probable wind velocity and direction 
and the ground handling characteris-
tics of that airplane, and considering 
other conditions such as landing aids 
and terrain. 

(3) The operation is authorized by 

management specifications. 

(d) No program manager or other per-

son may select an airport as an alter-
nate airport for a turbine engine pow-
ered large transport category airplane 
unless (based on the assumptions in 
paragraph (b) of this section) that air-
plane, at the weight expected at the 
time of arrival, can be brought to a full 
stop landing within 80 percent of the 
effective length of the runway from a 

point 50 feet above the intersection of 
the obstruction clearance plane and 
the runway. 

(e) Unless, based on a showing of ac-

tual operating landing techniques on 
wet runways, a shorter landing dis-
tance (but never less than that re-
quired by paragraph (b) or (c) of this 
section) has been approved for a spe-
cific type and model airplane and in-
cluded in the Airplane Flight Manual, 
no person may take off a turbojet air-
plane when the appropriate weather re-
ports or forecasts, or any combination 
of them, indicate that the runways at 
the destination or alternate airport 
may be wet or slippery at the esti-
mated time of arrival unless the effec-
tive runway length at the destination 
airport is at least 115 percent of the 
runway length required under para-
graph (b) or (c) of this section. 

§ 91.1039

IFR takeoff, approach and 

landing minimums. 

(a) No pilot on a program aircraft op-

erating a program flight may begin an 
instrument approach procedure to an 
airport unless— 

(1) Either that airport or the alter-

nate airport has a weather reporting 
facility operated by the U.S. National 
Weather Service, a source approved by 
the U.S. National Weather Service, or a 
source approved by the Administrator; 
and 

(2) The latest weather report issued 

by the weather reporting facility in-
cludes a current local altimeter setting 
for the destination airport. If no local 
altimeter setting is available at the 
destination airport, the pilot must ob-
tain the current local altimeter setting 
from a source provided by the facility 
designated on the approach chart for 
the destination airport. 

(b) For flight planning purposes, if 

the destination airport does not have a 
weather reporting facility described in 
paragraph (a)(1) of this section, the 
pilot must designate as an alternate an 
airport that has a weather reporting 
facility meeting that criteria. 

(c) The MDA or Decision Altitude 

and visibility landing minimums pre-
scribed in part 97 of this chapter or in 
the program manager’s management 
specifications are increased by 100 feet
