This might help, written for microlights but equally applicable to a light aeroplane such as a C150.
C150 TODR: 419m / 1375 ft; LDR 328m / 1075 ft; climb rate 670 fpm (D-G models)
PA38 TODR: 445m / 1460 ft; LDR 471m / 1544 ft; climb rate 718 fpm
I can't help think for for a 2-seater, low-ish hour pilot, and a short field, he'd be much better off with a microlight anyhow. For example:
MXP 740 Savannah with a Jabiru engine: TODR: 198m / 650ft; LDR 140m / 460 ft; climb rate 740 fpm
Sky Ranger 912: TODR: 254m / 833ft; LDR 250m / 821ft; climb rate 860 fpm.
(Not to mention that most microlights are years ahead of most Cessna-singles in terms of comfort, performance, utility and operating costs).
