The Learjet 40 matches the 45 exactly where it matters most to a charterer in a hurry — 465 kt, the highest top speed in this category, a figure the two of them share and nothing else here reaches. What it gives up is size: 212 in of cabin against 237, and seven seats against nine. What it gains is runway. Takeoff is 4,680 ft against the 45's 5,040, which is not a dramatic saving but is enough to change which airfields appear on a shortlist. Baggage is 65 cu ft across six bags, the same as its larger sibling.
The cabin is 61 in wide and 58.7 in high, so the cross-section is the 45's as well; only length and seat count separate them. For a party of seven that is often the correct trade, because two empty seats on a nine-seat aircraft buy nothing and the shorter field requirement buys something on every leg. Production has ended. Set against the CJ line, the Learjet 40 answers a different question: the CJs are chosen for the runway and the operating simplicity, the 40 for the speed, and at 465 kt it is quicker than every Citation in this class.
